Ask HN: What tiny purchases have disproportionately improved your life?

What cheap yet very useful things have made a substantial change and improvement to your life?

For me it has always been USB flash drives. I'm scared of getting ransomware'd one day, but I am safe in the knowledge that I'd have to have every thumbdrive I own plugged into my PC for some real damage to happen. They are a lifesaver, and they get cheaper every year too!

Light sensor outlet covers! They're pretty handy for walking around the house at night and not stubbing a toe.
Seconding these. I put them in the hallway between my bedroom and bathroom. They automatically shut off when it gets light.
A dedicated tool created to cut through cardboard boxes, roughly $20-30. When you have gigantic boxes to break down, using a straightedge or knife isn't going to "cut" it. Saves a LOT of time for me as it's significantly faster to use.

Using cooking vinegar in place of liquid softener in the clothes washer to remove moldy / gym sock smell from the drum and clothes. Only need to apply once every few washes and is less than $1 worth of vinegar to do the trick. I just fill the softener compartment with it. I've spent a lot of money on products that claim to remove the smell, but vinegar has consistently done the trick.

If your car's AC also smells moldy / gym socky, you can buy a foam spray that's designed to remove it that you put into your AC vents for around $35 that will clear it up immediately. I've watched youtube videos suggesting lysol but it did not work out for me on two cars. This did.

Can you share the name of the tool for cardboard boxes? I would love to buy, I've damaged many surfaces trying to cut down a box using a box cutter.
I used to be a kitchen manager and we would break down hundreds of boxes in addition to our regular duties. I would knuckle-punch (frog?) the tape, rip the flaps, and fold a box in one motion. These would be stacked in the recycling dumpster. What is the knife used for?
Cutting can save a bit of the space that the fold adds to the stack.

If you don't need the extra space, probably not worth the effort.

Is also nice if you are dealing with mixed sizes of boxes. Cut them to roughly the same size for stacking.

(Not the op, so I could have the wrong motives...)

I got one called "Worx ZipSnip Cordless".

Pretty happy with it.

I got one too and love it. CANARY Corrugated Cardboard Cutter from Amazon.
what type of vinegar do you use on laundry?

For cars, sometimes it is as easy as changing the cabin air filter.

I'm not them, but I use distilled white vinegar. You just want mild acetic acid with no contaminants.
Vinegar works great on gym clothes! I just discovered that too.
What is the name of this foam spray and/or what should I search for?
this isn't super cheap, but relative to the competing products, it is very cheap - A 43" 4K monitor from TCL is ~$300 (they used to be like $220, but I think a new model has supports 120Hz instead of just 60Hz).

It's the equivalent of having 4, 23" 1080p monitors, all smooshed together with no bezel. You can see sooo much. It's not as high of a dpi, but I switched to it from a 39" ultra curved widescreen that was over $1000 and I can see even more.

Another tiny set of purchases that makes life easier - buy different colored and patterned cables instead of just black. I can actually find what I need so much quicker instead of trying to trace a single black cable through the rat's nest.

> I can actually find what I need so much quicker instead of trying to trace a single black cable through the rat's nest.

Another way I've solved this with standard black wires is to get multi-color tape and then put tape around both ends of the wire. You can get a 10 pack of assorted colors for like $10. It's handy if you have a rats nest of black computer wires.

I used to do the same thing for years until I got tired of Windows' horrid handling of a mixture of 4k and HD monitors (I thought they would fix it but things just got worse). I went with an AOC 2560 32" curved gaming monitor...zero issues.
you're talking about the DPI scaling between the TV and a laptop monitor? I agree it's annoying. I've solved it in two ways - I got a second 43" "montior", the other is I just keep my laptop closed. I feel you though.
I bought a little Epson label printer, and I print tags for both ends of a cable. Same idea, but sometimes it's hard to get a variety of colors, depending on the cable.

Also works magnificently for trying to figure out what's plugged into the multi-outlet next to the entertainment center. "This is the TV plug. This is the amplifier. This is the NAS. This is the switch." It's so much easier when the switch's power adapter has a big "SWITCH" label on it.

a weighted blanket. now i sleep like a baby :)

I got my wife one of these and was surprised when she was away how well I slept under it
What a great question!

* A very long USB-C cable from an Apple store. I get jealous looks when I break it out to charge my phone.

* Scented candles from Aldi. It's such a quality of life boost to have the place smelling nice. They last ages and cost nothing.

* A creme brulee hand blowtorch. Surprisingly useful! Excellent for lighting aforementioned candles instantly, without burning your knuckles.

* A real P3 respirator with replaceable filters. I've seen the rate that people go through disposable masks. Replacing the filters every few months is vastly cheaper than that! And bonus, it's at least an order of magnitude more effective.

> Scented candles

Generally candles emit fine particulates which is unhealthy.

If you're really concerned, just use a candle snuffer to blow it out and don't huff the fumes
That's not a problem as long as they're wearing the P3 respirator!
Often a real P3 respirator has a valve to prevent fogging with doesn't filter what you exhale though so you're not helping the pandemic.
It's not ideal of course, but I don't think it's fair to say I'm not helping. Almost nobody wears a mask that truly filters what they exhale - their main functions are to trap moisture and stop you projecting droplets with your voice. My mask does capture a lot of moisture, as evidenced by the condensation inside, and the valve redirects my exhalation sideways, so I think that's likely at least as good as the cheapy surgical-style masks which are common.

Also, I tend to take the view that the best tool available to me to not spread Covid is to not catch Covid. It's apparent to me that relying on the people around me to wear masks and be sensible is not a viable strategy for avoiding transmission events. When the prevailing attitude is that the pandemic is over, I do not feel it is selfish to protect myself to the best of my ability.

3M is now making a high-quality respirator that has an optional exhalation filter attachment. I forget the model number but you can find it on the grainger website.
> A creme brulee hand blowtorch.

Seconded. It's absurdly nice to have a focused torch when you need one. And most are refillable, making them better than most lighters.

Could you make s’mores with that ?
Yeah without a doubt
a phone case wallet, I love having one less thing in my pockets

back in the day it used to be

1) phone

2) small digital camera

3) keys

4) wallet

Now it's just phone & keys. Lovely!

Link? I'm curious to see what yours looks like.
On a similar note I can recommend a key case. I have a model that is a leather pouch with a zipper and a small key chain inside (I think I tried one with hooks before but the hooks broke quickly). Much more comfortable than having keys in my pocket. No more holes either.
I also love minimal stuff in my pockets.

In addition to the phone wallet case, I installed electronic locks on my home, so I could stop carrying keys around.

My second hand Netgear Nighthawk router is the best $100 I've ever spend. Never had connectivity issues ever again.
Which model? Did you get it from eBay?
I have the netgear nighthawk r7000. It's a legendary model and has passed the test of time.
Model would be nice, I have Nighthawk too - R7960P - and it's buggy as heck, refuses to upgrade and very flaky. Very disappointed.

Upd: I see you specified the model below, didn't notice that, sorry. Will check that one out, maybe it's better?

Cheap attachable toilet bidet
I've had the Tushy bidet for a couple years now and it's great! Overall it has made me feel a lot more hygienic and I only use a small amount of TP to dry off now.
Squatty Potty is good too and has hilarious ads :)
How is that any better than just spreading the cheaks before sitting and resting the elbows on the knees?

Serious question. I just think good toilet etiquette/hygiene is not being taught. For example, wipe any sweat and hairs off the seat before putting the lid down (or seat up if no lid) before flushing.

Is there some issue with the cold water? If you live in a cold climate? Asking for a friend :D
You can just ask for yourself, this is HN not Reddit. You get used to the cold after a few uses, but there are luxury models that allow temperature control.
You would think having cold water applied to your underside would be uncomfortable, but it's not really. Sure, its a bit of a shock sometimes but you get used to it. And honestly, not having to wipe (and wipe and wipe) is 100% worth it.
Where I live, the ubiquitous variant is attached to the faucet on your washbasin, so you get to set any temperature you want. (Most lavatories have the washbasin close enough to the throne that you only need to lean forward a bit; can get awkward in handicap toilets though.)
Mail processor. I spend $20/month, they receive all of my mail, open it, and digitize it. They discard the junk mail if I want. I never have to visit a mailbox again. I can even register it as my address on my driver's license and for my vehicles.

EDIT: The service I use is https://www.sbimailservice.com/.

Can you share the mail processor that you use? Or how you went about finding one?
https://www.sbimailservice.com/

Found them because they cater to the RV and cruising (sailing/motoring around the world) folks, and that's my circle of friends.

(no affiliation other than as a customer)

Wow I’d be far too paranoid about them leaking things
Why? That's a federal offense in the USA at least. If you're afraid of that, you may as well fear any mail delivery person.
The fear is understandable, as mailmen don't open and digitize your correspondence. It's a new risk, however small, that you have to consider.
They have controls as most of these folks have to have (background checks, access controls, physical security, etc [1]). Still better than randos pulling your mail out of the mailbox in front of your residence imho. Its a shim until the last of need for paper mail gets deprecated, as I still need to receive correspondence of importance via snail mail (business filings, IRS, etc).

[1] https://www.sbimailservice.com/security/

(all commercial mail processors you consider should have similar controls in place, make sure you ask!)

Some people in my area use these services and I've considered it because mail theft is a big problem in my area. Organized rings doing package theft, identify theft, and all that. So for us at least, it seems significantly safer than having it delivered directly. Personally I just go paperless as much as possible and have the post office hold my mail (another popular response).
PO box?
The problem with PO boxes, besides being in short supply, is all the places that can't accept or ship to PO boxes (DMV, voter registration, private parcel services, insurance companies, ...)
While it cannot be used as an option for "your physical residence.... in legal documents" -- voter registration or the DMV -- the USPS does offer "Street Addressing Service." It provides a street address you can use with UPS, FedEx, and others. P.O. Box 59 would be 500 Main Street #59 (for a Post Office located at 500 Main Street). The service is free. (I just filled out the form two days ago.)
(comment deleted)
If you want a less expensive 'lite' option, you can sign up with the USPS and they will scan your incoming envelopes and email you the images. This at least alerts you when something that should have made it into your mailbox, doesn't.
I've never heard of this kind of service. It sounds like something I want ASAP. Any downsides?
With any mail processor, you're sort of married to them once you start giving out the address. I spent months agonizing over who I was going to tie myself to (and did quite a bit of research from HN folks [1] [2] providing their recommendations). In the end, I picked the vendor I did because I only get a few pieces of mail a month, they're responsive, and I can use them for residency purposes [3] (as my long term plan is to bounce from the US and be an expat). And unlike a startup, they have some longevity track record and are likely to continue to exist into the future, which is important when everyone is going to have them as your mailing address.

I had such a service for a while. The only two issues I ran into was:

- Getting the physical mail out of them was hard. In theory they kept main for some number of days if I needed it physical for some random reason, but the two times I needed to have them forward me some important document, it had already been shredded. All in all, this was a minor edge case really.

- One company, All State, could not for the life of them realize that I did not live in some PO Box in a different state. They kept changing my rates to the state of the service, and I had a confusing call with a CSR each time where I tried to explain my mailing address and my residential addresses were unrelated. All State was the only company I ever encountered with this issue, everyone else that needed my home address had no trouble with this concept. I solved this by ditching All State.

I only stopped using them because they got bought out and only kept business accounts. I should look for a replacement company, it was very useful.

From what I’ve heard the addresses for these services are being tagged as “not a residence” in some database. Then some services aren’t accepting them as a valid address.

Similar to how phone numbers can be tagged VoIP and won’t be accepted for 2-factor authentication.

Yeah, I use the same. Super convenient for when I work on the road, never have to worry about not getting my mail. For those who are asking I use TravelingMailbox.com, it was recommended by people when I moved onto my boat years ago and even now that I'm back on land I still keep it up.
I might need to do this when I start my vanlife. What service are you using?
(comment deleted)
I use VirtualPostMail and like them for a couple of reasons: - Easy to set up autoscanning so I just get PDFs with all incoming email. - Easy to get things mailed to me. - Can be a registered agent for my business (at least in CA). - Can handle check deposits for me.
what happens when your bank sends you a new atm card when the old one expires?
They priority mail me the envelope, international mail if out of the country.
I tried to priority mail the keys to a mailbox slot back to someone last year so it would go to their doorstep and not the mailbox slot. Post office put it in the slot anyway ostensibly due to covid. Had to get new keys made. I should have pushed for a refund.
Wow, I never knew this was a thing.
That's interesting. Seems like an expensive /dev/null

Varying length of phone charging cables.

Bought a couple of bundles of iPhone charging cables from Amazon that were 3ft/6ft/10ft in length with charging attachment from my old iPhones.

It's such a great feeling to use the phone from any part of my place without having to worry about length of the cable.

I keep a couple of the longer cables in my car too just in case someone wants to charge on a long trip.

> Varying length of phone charging cables

For me it's Varying lengths of USB-C charging cables, and a bunch of USB-C -> Micro and USB-C -> Lightning adapters so no more looking for the right cable.

Oh yeah. My friends really appreciated it when I upgraded to two 10ft cables snaking out from behind the couch. Finally they could charge while lounging anywhere.
Same, but Anker cables with lifetime warranty. One dies and without much more than an email and I get a replacement.
A vacuum insulated water bottle. It reminds me to drink more water and it stays cold the entire day.
Came here to post this. Also, vacuum insulated mugs and tumblers for hot/cold drinks as well.
Thermos sells a $30-33(?) one in two different shades of silver — the one with with green rubber(silicone?) grommets.

After performing the research, I can confirm you'll struggle to find better in any category you've been disappointed in previously.

Agreed entirely. Mine is a Yeti Rambler with the "chug cap". Absolutely amazing and indispensable.
I was chronically dehydrated for much of my life because I can't tell when I'm thirsty - my mouth doesn't send me the right signals. About 8 years years ago I bought a 48-oz Nalgene bottle which I fill up in the morning. It's big so I have a constant visual reminder right there on my desk in front of me, and I have no problems finishing it off and often refilling it in the early evening. It's absolutely improved my health.
Target sells a Zulu Ace water bottle that I really enjoy. The bottom screws off, so it's incredibly easy to clean.
I remember leaving mine in my car in the middle of summer. After work, I tried to pick it up, but the metal on the outside was so hot I couldn't. Inside, though, the water was cold and there was still ice sloshing around. It really impressed me.
A Koshi chime. It makes a simply lovely sound.
I’ve used an $8 gerber shard keychain tool for over 10 years.

It opens cardboard boxes, pries open covers, cuts strings, and drives the occasional screw. All without worrying about losing a Swiss army or leatherman, and it’s airport and government building friendly which is big for me.

> opens cardboard boxes [...] cuts strings

How does that work? I looked it up and it doesn't seem like it has a knife. (Not that you'd want something that sharp in your pocket unprotected anyway.)

The little “v notch” that they call a wire cutter is sharp enough to go through packing tape. Not sharp enough to bother you though, any more than a house key on the same ring.

It’s not a tool I’d use to break down 1000 boxes a day, but it’s fine for an Amazon box or two.

For the same reason I keep a Swiss+Tech ST53100 Multitool on my keys. It's as long as a key, and like your tool it doesn't have a blade so is airport- and government building-safe.
Modern pressure cooker saves 50+ hours of my time per year in cleaning and cooking time, not to mention gas costs.

Not "tiny," but the cost/benefit ratio is significant.

My wife and I got one this spring and use it for most dinners now and love it. Quick, easy to clean, and the kitchen doesn't get near as hot as compared to the oven.

One of my favorite things we make with it is refried beans. Makes canned refrieds taste like dog food.

I don't know what it is but I find pressure cooking brings out the good flavour in beans, and less of the flavour people describe as "beany" - like a raw bean from the pod would taste.

They also have a smoother texture than cooking in a pot. It's my favourite way to cook them too.

A dog.

Overall for around 100 bucks a month in food/trifexis the value a dog brings to your life is massive.

People will constantly talk to you so youre socializing.

There's a creature that loves you unconditionally which is a really cool feeling.

Theyre a ton of fun so it's hard to be bored.

They're good for getting exercise as they always want to play.

And more.

Theres studies that say owning a dog increases your lifespan as well.

I get what you're saying but quite a few of my neighbors have dogs that they leave to roam the garden during the day whilst they're out... And said dogs will bark at everyone and everything, which causes me stress (noise pollution). Please only get a dog that you can spend a lot of time with.
Yeah, dogs are pack animals.

If the owner has to leave every day ,they should be bringing their dogs to doggy day care or have another dog to keep it company.

I personally view leaving a dog alone all day as abuse.

What breed of dog? How much is the insurance?
I got an Aussie. No insurance.

I would just pay the 40 bucks for the vet visit if I need it which I haven't in two years of dog ownership so far.

Not sure what your financial situation is, but emergency procedures at the vet can get very expensive very quickly. I would very much recommend insurance even if it is hardly ever needed. Also, starting with insurance later will get you exclusions on the policy for age related issues.

I'm paying USD600 a year per dog in insurance. It already paid for itself for several years with one stomach bug gone bad that needed somewhat intensive care at a vet hospital for several days.

Thanks for the tip. I have to think about it. I don't know anyone who has gotten it out of a handful of people. But it's def f something to think about.

Glad your pooch is ok!

As someone with experience in the veterinary industry I highly recommend pet insurance unless you can afford paying out-of-pocket for surprise procedures. It can be expensive.

Also, be sure to take your pet to a vet at least once a year for annual checkups and preventative care. Do not wait for a reason to go in. So many people call in to have their pet looked at when some weird symptom appears, only to discover that their pet now has an issue that could have been prevented if they had been visiting regularly.

God, I've low-key been wanting to adopt a husky...
Huskys are awesome. I see them at the dog park. They're gorgeous dogs and have a ton of personality.

I don't know if I would get one if I lived in a tropical climate though. Like the southern U.S. states.

West Coast or New England...hell yes!

I've read they adapt okay to tropical climates!

I live in PR and I know quite a couple husky owners, the key according to them is to just try to keep them hydrated, cool and off hot pavement.

Yeah I live in Louisiana in southern U.S. and see tons of huskies at the dog park and they're playing as hard as the other dogs and seem very happy so they're probably fine!

I read the double coat protects from the cold AND the heat.

I shave my Aussies top coat every spring just for posterity and he does fine in the summer.

You should get one! Huskys are totally zany wonderful critters!

They were bred for pulling a load for many hours, day after day for hundreds of kilometres. So, they need a lot of exercise or they get bored and will find their own way of getting stimulation (i.e indulging in what we could consider mischief). They are also excellent diggers and can jump over surprisingly high fences/walls. So, they are excellent escape artists too.

If you are experienced with dogs, it shouldn't be an issue and it will be a lot of fun as they are clever and to a degree independent too. On the other hand, if you aren't really clear about what you are getting into, it might spell trouble.

In any case, I wish you luck and hope that you find a suitable canine companion.

Libby - I used to buy so many Kindle books and had an expensive Audible subscription a year ago but all that stopped when I discovered Libby. I can read ebooks and audiobooks right in the app using my local public library card for free and the entire UX of the app is just beyond awesome. I can now read/listen to 5-7 books a month using Libby.
Does this work with the eink Kindles?
You can transfer your ebooks you borrowed from Libby to Kindle eReader for sure but you can't do that with Audiobooks though.
The e-ink eReaders from Kobo have an integration with Overdrive, which is by the same company as Libby. Kindles are designed to sell you more books from Amazon.
Yes. You check out a book in Libby and tap “read with kindle.” Then it shows up in your kindle library like any other book.
I do this with the Overdrive app and my local library. I think they have Libby also. I prefer the audit books during my commute to work.
Libby is pretty much same as Overdrive just in a nicer package. In fact it's developed by the same company that created Overdrive so you can easily switch from OD to Libby. And I'm sure you won't regret as Libby has such a great polished UI compared to OD.
The winning combo for me is Libby + Hoopla + Library Extension for Chrome. Anytime I see something I'm interested in on Amazon, Goodreads, etc. - I immediately see (and can store for later reading/listening) if it's available via my local library. Can't count how many books I got this way, totally free.
A webcam I bought for a girl who had no money to spare and lived abroad, so that we could see eachother regularly. We eventually became a couple and moved together.
I have a similar story about buying a parking space in a garage near my place when I lived downtown because my then girlfriend was always bothered by trying to find parking. It worked pretty well, now she's my wife.

Best $40 / month I ever spent.

Eye Mask - I sleep so much better and longer with one on. I recommend one that doesn't sit on your eyes directly (has a bit of concavity).
I second this. I sleep so much better with it on. But I do need one with concavity, otherwise it hurts my eyes after a while.
May I ask why you don't manage to make your room completely dark instead of wearing a mask?
Eye masks are far cheaper than new black-out curtains.
I strongly recommend the Manta Sleep mask (no affiliation, just really like them). Adjustable non-contact eye cups, plus you can get different eye cup "mods" like cool (keep in freezer) or warm (microwave) cups that feel amazing. Amazon, or mantasleep.com.
Can second this, I got a Manta a few months ago and I love it. I sleep better when it's pitch dark and the sleep mask helps ensure that it is.

The only nitpick is that if you're a side sleeper (I am) it can be a little uncomfortable depending on what kind of pillow you use. I use shredded memory foam pillows and they're pretty firm.

The Manta has thicker materials compared to other masks, so when I turn my head on my pillow, the mask is often pushed off my face slightly. You can tighten it of course, but then its a comfort tradeoff. I wouldn’t recommend manta for this reason.
Huge water bottles- mine is 40 oz.

I figured out that I pretty much always drink 2 or three bottles of water per day, no matter what size of bottle I use. So a big old water bottle doubles the amount of water I drink in a day

I just borrow the kids' used softdrink PET bottles for a while. No need to wash them out or anything, just rinse out the few leftover drops of Coke or 7-Up first time you fill it up, and switch to a fresh one after a while, let them recycle the old one.
Food scale I got at Target for like $20.

Over quarantine, I started getting fluffier than I'm comfortable with and reached my highest weight ever. I eat healthy, so my only guess was that I was eating too much. Simply adding a food scale made me cut 15 pounds in a couple months.

How do you know how much you should eat?
(Not OP, but went through a similar process)

The best way (for me at least) was to track my calories, using the food scale to weight things and nutritional labels (or looking things up in Google) to figure out the calories. MyFitnessPal for logging everything.

If you're asking how to know how many calories you need - search for TDEE calculator online, which will give you an estimate number of calories needed for maintenance, or how much for weight loss, given your height, bodyweight and activity level. But - these are just estimates! Track food intake for a month, see if you went down, if not, start targeting fewer calories (or more if you went down too quickly for your needs).

This is a great question! This was something I was stuck on for a long time.

I used to think this would be an extremely time-consuming thing that would be very annoying to learn. What really struck me is how easy this actually turned out to be. In fact tracking what you eat will save you time. Here's how.

People talk about "counting calories". But here's the problem with that: you can eat nothing but donuts throughout the day and stay within your calorie limit, yet it's still unhealthy. What gives? How do we know what is healthy and what isn't?

Enter macros. Calories in food are made up of three "macros", which are: fat; carbs; protein.

So just forget about calories. What you want to know is how many macros you need per day; how many grams of fat, grams of protein, and grams of carbs. The calories will work themselves out.

Okay, how do you find out? Super easy. You can use a calculator like this one: https://www.bodybuilding.com/fun/macronutrients_calculator.h...

For me, every day I aim for:

154g Carbs

150g Protein

32g Fat

Now you might be thinking "Wow that sounds like a pain in the ass to track. How is it even possible to track that?"

There are apps that do this for you. My favorite app is called "Macros" https://play.google.com/store/apps/details?id=com.josmantek.... and there are a lot of other good ones out there.

Here's how it works:

1. Look at your food nutrition label (for example, fat-free Greek Yogurt)

2. Find the serving size (170g) and enter that into your app.

3. Find the macros grams (0g Fat; 7g Carbs; 17g Protein) and enter those into your app.

That's it. Your app will now have the nutrition facts of that food item saved forever and you only need to follow this process for new foods / new ingredients. Over time, you will gradually build a library of foods you like to eat.

Whenever you're ready to eat, you select one of your saved food items like "Greek Yogurt", and it will simply ask you the weight of your food. Enter in any weight you want, and it will automatically calculate how many macros/calories it will provide you. If it's too much, adjust the weight down, and if it's too little then adjust the weight up.

Once you decide on the perfect weight / macros, then you use your food scale to get exactly what you need.

To wrap things up, this also saves you time because now it enables you to plan ahead exactly what you want to eat and how much you want to eat. When it's time to eat, you just open up your plan and follow the instructions, no more staring blankly into the fridge.

1. If you don't do any sports, you need 50 grams of protein daily (roughly, you can adjust somewhat if you are taller/shorter). If you do some sports, 100 to 200 grams of protein daily. Those are numbers from scientific papers, do your research if you don't believe me. Fats and carbs can vary and you can experiment depending on how you feel.

2. Start to measure and write down the weight and macronutrients of everything you eat.

3. Measure your weight every morning and adjust calories every week by 100-200 depending on your weight gain/loss. But do not fall below the desired protein amount. You should learn to do it reliably within a month.

4. Take your average daily weight every week and try to not lose more than 1-1.5% of your body weight weekly (increase calories if losing faster).

5. When you reach your desired weight, start increasing by 100-200 calories daily, until you reach equilibrium for your weekly average weight. That is your optimal calorie intake.

6. Start learning patterns and you'll figure out how (what and how much) to eat in order to maintain your body weight. After several months of daily calorie tracking, you should be able to eat within reasonable margin of error without measuring anything. At this point you can stop measuring calories.

7. Every now and then, when you gain several extra kilos, repeat the above process for a month or two.

A sous vide circulator. $100-200. Never eat dry chicken again, extremely consistent results, flexible (I'm making yogurt in it right now), and stupid easy.

I got this one (https://www.chefsteps.com/joule) but Anova is much more popular (https://anovaculinary.com/anova-precision-cooker/)

I got a deal on one with WIFI and I love it. I use mine in a insulated cooler with a hole in the lid. I usually don't know what time I will get home till after lunch. I can throw in frozen meat before I leave for work, and then start the thaw and cook process whenever. If its going to be a long day I will add ice to the water bath.
Love my Joule. Been using it for years now it feels like for an amazing amount of things. Also the size and waterproof aspect of it is unbeatable. Good customer service too now that breville owns em.
I am not sure if cooking food inside a plastic bag is healthy.
For what it's worth, you can get reusable, resealable silicone bags which work well and are less likely to leach into your food.
An electric toothbrush and floss. Brushing with a regular toothbrush doesn’t give me the clean/fresh feeling my electric toothbrush does. The model I have was maybe $25 or $30.

Using the electric toothbrush and flossing before bed every night, I feel like in my morning my mouth actually still feels fine. Of course I would never start my day without brushing, but my mouth doesn’t feel icky when I wake up in the morning. Sorry if that’s TMI.

Brushing after breakfast, rather than before, is recommended for maximum cleanness.

If you only brush once a day, brush last thing before bed.

I remember hearing a long time ago that brushing before eating is better. Sugar reacts with plaque to form acids and brushing temporarily removes plaque. So eating straight after brushing doesn't really do anything.
I've heard this also but it doesn't make much sense to me. If you brush after you eat, wouldn't it remove the plaque, sugar, and any possible acid? Any plaque that remains will have little to nothing to eat.

If you brush before eating, there will still be some plaque left and once you eat there should be copious amounts of sugar and food for it to snack on and quickly multiply + produce acid.

The way I understood it the acids in the food make the enamel softer. Brushing while the enamel is softened can result in brushing away the outermost layer of enamel. Waiting until 45-60 minutes supposedly allows the saliva to normalize the pH level so that the enamel is at full strength again.
Brushing after you eat is not recommended because you're a lot more likely to damage your enamel that way, especially if you've eaten anything acidic.

Acidic foods temporarily weaken your enamel to the point that even light brushing can damage it.

It is, however, disgusting.
I'm the opposite: I think it's disgusting people brush before breakfast, just to dirty their mouth right up again with breakfast and walk around un-brushed afterward
Do you brush your teeth after lunch?
Yes, why wouldn't I? I brush at least 2-3 a day, with flossing, after every meal. I've never understood people who can't afford 6 minutes a day to properly care for one of the most important parts of our bodies (ie teeth).
It’s the other way around. Food doesn’t make your teeth bad. It’s bacteria in your mouth, eating your food and shitting out enzymes that soften and damage your teeth. So before you eat, make sure those bacteria are wiped away by brushing your teeth.

If you brush immediately after eating, you’re partially brushing their enzyme shit into your teeth…

I was interested in a Waterpik but I thought it would be too difficult to maintain. I found out about both a toothbrush and an oral irrigator that you hook up to your shower which are really cool.

There are also some tricks for oral hygiene that you don't get traditionally or when you go to the store for toothpaste. You can try putting a drop of Dragon's Blood on the toothbrush or brush with a bit of ozonated oil to help gum issues.

I purchased a generic water flosser from Amazon. Works great. I put an ounce or two of mouthwash in the reservoir when I fill it and I occasionally clean it by washing the reservoir. Very simple to maintain and an extremely effective oral hygiene tool. I have many teeth that are very close together and floss just breaks constantly (I can use those floss tools but don't like throwing them out each time).
Alright I'll bite, what brand does both? And more importantly, what in the world is Dragon Blood in this context?
Croton lechleri! It's been used traditionally for a lot of stuff and the active constituent is in an orphan drug to help GI issues with cancer. It helps wounds of all sorts and gum issues.

You can find the oral irrigator/toothbrush combos for looking for faucet oral irrigator on amazon. Maybe I'd misremembered the shower ones that are harder to find for the combos of both, but they're easy enough to find for a faucet adapter.

A plastic tongue scraper. Just brushing my teeth didn't provide the satisfactory result until I started to also brush my tongue. And the scraper does a much better job of it.
Some that come to mind.

__Health__

Melatonin. There is no other way for me to go to bed and this knocks me right out (I use 0.2 - 0.4 milligrams).

Sleep mask (no more waking up because a stray light hits my eye)

I'd say sleep earplugs but I have a sound in my ear, but otherwise earplugs

Mosquito repellent scent (for sleep as well).

Silicon earplugs when going out, I never thought I'd get ear/hearing damage because I didn't go out a lot. I was wrong. They protected my ears after I noticed I got some ear damage.

A dumbbell (used at times between breaks to move a bit)

__Other__

Fuet (another HN'er once posted this as such at some thread years ago I can't remember, and I agree). It's a sausage and IMO too good as a snack.

LG 4K monitor for about $350

Moving labels. Got a bunch of moving labels for a few bucks, and slap them whenever I need to label something. Apparently, I tend to label my external HD's mostly and a few boxes that have specific items in them (e.g. only USB cables or power cables, etc.).

Not a purchase but a lifehack and since I see many responses are about cables I guess it's relevant ;-) Instead of spinning your cables in a circle, spin them in a figure 8 (two circles). Somehow it's harder for them to get weirdly tangled when you store them like that. See: https://youtu.be/buVUvnM_AzU?t=104 (I don't use the other life hacks :P)

For some people, me included, melatonin can cause an uptick in very real feeling and (depending on mental state) very weird dreams. Do be mindful of that. On the other hand if you're practiced at lucid dreaming this can be a real trip.
If you are sleep deprived, anything that helps you sleep better can result in an uptick in very vivid, strange dreams. It is a common side effect of quitting caffeine and any number of other things.

Anything that suddenly and dramatically improves your sleep quality can potentially have this effect.

I've found that the "weird dream" side effect is very dose responsive. Most melatonin supplements I see include doses much higher than are required, in the 3-5 mg range. Very small doses (as the OP mentioned, in the 200-400 microgram range) should be plenty as a sleep aid and (for me anyway) avoid the enhanced dreams.

I will sometimes take 5 mg when I wake up in the middle of the night in an attempt to induce lucid dreaming, although since I've fallen off of my dream journal my LD abilities are diminished (even with the melatonin).

Melatonin is not recommended for sleep. A better combo to take would be 200mg L-theanine and 500mg Magnesium Threonate. Melatonin can disrupt your natural melatonin production and those supplements are also notoriously inaccurate in terms of dosage some containing anywhere from 0.2x to 2x the amount listed. Melatonin is probably acting more as a placebo for you now.
Melatonin also works in low dose. You don't need the popular 3mg pills. After nearly 20 years as a night owl and struggling to retrain myself to sleep at night, I finally managed when I followed the advice from this article https://slatestarcodex.com/2018/07/10/melatonin-much-more-th.... Every night I'd take between 0.1mg and 0.3mg. It worked flawlessly for 3 weeks. I didn't experience any sort of adaptation. After 3 weeks I tried to stop. Although I could sleep well without it by then, I noticed that my night sleep was still too sensitive and prone to interruption, at the slightest disruption. I ended up taking it for 6 months. It never failed. I eventually managed a proper sleep without it and completely became a night sleeper.
I'm sure it doesn't work for everyone but we blind tested it for my wife. Nights with no melatonin, but an identical pill, meant no sleep.
> sleep earplugs

Not the best practice to insert stuff inside the ear. Instead, there exist pretty flat and efficient earmuffs, e.g. from 3M, comfortable for bedtime.

Couldn't find comfortable ones for bedtime (The Netherlands doesn't have a lot of earmuffs offerings I feel), but I bought some 3M earmuffs anyway because I didn't really know about them.
> Instead of spinning your cables in a circle, spin them in a figure 8

Also known as "butterfly coiling" rope, cable or hose. The alternating turns mean that every twist has a counter-twist, so you don't end up with the tension that causes cables/ropes to tangle up.

If you have trouble sleeping have you tried a weighted blanket?

My girlfriend brought one recently and it’s weirdly relaxing having something so heavy resting over your body. I’ve found it helps me with just lying still and I think the weight subconsciously makes my body feel heavier and more tired than I actually am.

What about the warmth? I've thought about getting one of these, but what worries me is that it will be too hot.

My problem is that I can barely fall asleep if it's too hot, but I also need to have some weight on me, so can't sleep with the blanket cover only, either. Summers are a nightmare..

For those, like myself, where Melatonin doesn't work well. Try 'Calm' brand magnesium drink it relaxes me and keeps me asleep, without the need for ear plugs. I've tried the magnesium pills and they don't seam to work, the drink mixture does.
I have written down a recommendation from somewhere to take Zinc, Magnesium and Vitamin B6, 30 minutes before bedtime.
