American shower heads suck. Everyone in Europe have "hold in your hand" shower heads, which makes it much easier to clean it up. I wonder why this is not a thing in the US.
Those can be had for 10 bucks at home depot. They simply screw on with some plumber's tape.
Not sure why you're being buried, because this is absolutely true. Takes about 5-10 minutes to install, with most of that time spent cutting them out of the clamshell packaging.
Can we stop with the 'everyone in Europe' thing? It's almost never true. I live in rented accommodation in London and have the same style of shower heads as in the article.

Here's a fairly prominent seller of bathroom stuff in the UK, with a wide variety of different shower fittings: http://www.bathstore.com/products/showers/shower-fittings/sh...

I think you are taking the statement too literally. The expression does is not meant as an authoritative statement that every single person does X but that in general X is the most common. I understand it is often used as an underhanded method of supporting ones argument, but the statement itself typically isn't literal. Likewise, in situations like this, counter points often fall prey to exception does not make the rule.

Living abroad in Russia and traveling across Europe, the parent is true that handheld shower heads are by far more common. In Russian apartments at least I suspect it's because showers tend to be very small so the angle for a fixed shower head wouldn't be possible except for straight down, which is also not how most showers are installed to deal with. Again in Russia at least many building are renovated USSR built ones, and the apartments were built to last - redoing plumbing is a challenge, so it's easier to just attach a handheld shower head to the existing faucet than it is to add plumbing to concrete walls.

The UK is the exception to a lot of rules when talking about "Europe".

The hand-held shower thing is by far the norm in Germany, Italy, etc. And yeah, it's great because it's so much more usable, and really easy to replace.

Actually, I'd say that even in the UK the detachable shower heads that can be attached to a fitting are most common - at least in my experience.

What you do get in nicer showers is both a large fixed shower head and a detachable shower head.

I have a good quality "water saving" type detachable showerhead. It's perfect for everything except filling the kids' plastic Ikea bathtub. So I installed (with a bit of hacking) the quick-connect system used on garden hoses on the shower head, and now we have the best of both worlds: using less hot water for showers, but quick filling of the bathtub.

If any of you entrepreneuring types want to make a kit and throw it up on Kickstarter, the idea is all yours.

Don't know the name, but there is an amazing faucet ending that looks like a normal one (not that plastic/metal bulge) and then you just slide in and out the different tubes. I was living in a house that had a roof terrace but no water supply, so only way to clean/water the plants that was ok, was to use one of these on the bathroom sink, looks almost like the original one, but when we needed, we slided the water hose there easily.

I can't find it now, don't remember the name, but I purchased it a couple years ago from Amazon, so I should be able to get the name if you are interested with a bit more time.

Funny. I have one of these in my home and never detach it.
Detachable shower heads are very handy when cleaning.
> I live in rented accommodation in London and have the same style of shower heads as in the article

I live in Germany for 30+ years and I also have lived in the US for a year. I can tell you from my own experience that US-styled showerheads (ans those horrible temperature selection thingies) are virtually unheard of in Germany. Every single shower I have ever used here in Germany had a detachable shower head.

Generally, everyone has a "hold in your hand" showerhead, except for hotels and rentals, cause the fixed ones are cheaper. I've got a "hold in your hand" one that I took from apartment to apartment, and is now sitting in my master bath, cause the one that was in the house was fixed as well!

It is. Lots of people have them, anyone who wants one can easily get one.
I have one and I only handle it when I am cleaning my shower. Coincidentally, I cleaned my shower head last month as more than a few ports had clogged up. I soaked it in vinegar for an hour, pushed a pin through the calcium encrusted ports and scrubbed it with an old, HARD bristled toothbrush. No crustaceans were observed.

One note: Hard bristled toothbrushes(stiffer than 'Firm') are THE BEST for cleaning small parts. Not so good for brushing your teeth unless you don't like enamel.

How would a hold in your hand shower head be much easier to clean up since the gunk mentioned in the article was located in the interior?

The same gunk would probably be present in the faucets as well.

And in the pipes too! I think we ought to take apart the entire plumbing and figure out how gross it all is. They wouldn't even believe how gross the sewers get.
The inside of pipes doesn't get exposed to the outside air like a shower head does. Less likely to grow the same kind of gunk.
It is easier to unscrew.

That's not much, but it's a large step when it comes to cleaning something that get cleaned once every 5 years.

Take your pick:

1. it's a ploy to out uppity Europeans

2. they would rather have a sucky showerhead than be like the French

3. it's to annoy you... you personally

4. They use US Customary Units... need I say more?

5. FREEDOM

It's probably related to the reason American banking is so backwards: it wouldn't surprise me if we got showers first, before handheld showerheads were a thing, while Europeans were still taking baths (it's amazing when I travel in Europe how many places still are bath-only!).

That said, I'd rather have a fixed showerhead than a handheld showerhead that I must pick up to use (i.e., some handhelds can be fixed in place): half the fun of a good shower is just standing there in the heat and steam, water running down one's head, not having to do anything. Waving a showerhead over oneself might clean better, but it's too much like work.

Apparently the answer is "gross stuff". I didn't see much more usable detail than that in the article?
"Gross stuff which can maybe cause weird diseases."
Or help boost our immune systems by exposure? I couldn't tell from the article.
That's the point of the article; they know almost nothing about it, so there are currently data collection efforts so they can get a big picture. From there they can ask the detailed questions like that.
Gross stuff which is actually a collection of microorganisms. And reading further, there's the idea that our exposure to this gross stuff may be beneficial and one of the few ways we're still exposed to it. Or harmful.

Very interesting stuff in my opinion. Have studies like this been made more accessible due to cheaper sequencing?

And seeing as our bodies are colonies of microorganisms...
Oh, I thought it was going to be the flow regulators. I keep meaning to remove mine.
A staggering number of people don't have access to clean drinking water and flushing toilets in the world, I refuse to start worrying about this sort of stuff so I won't be reading this article.
Do you also forego eating because a staggering number of people in the world don't have access to food? It's at least worth considering what it's in your showerhead since it could potentially cause a weird disease or something of the sort.
Or, as the article points out, benefit your immune system by leaving yourself exposed to what's in there.
It's not meant to be something to scare you; the intent is to get people interested in helping with data collection efforts. It's very possible the results turns out to be that most of these organisms are beneficial to us in some way, but we just don't know without the data.
“You may have worms,” Dunn told me. “There’s even some evidence in the Netherlands of little crustaceans.”

Ok so I have been living in the Netherlands for 46 years and I have never heard about crustaceans in our showerheads :) I can't find any sources about this on the Internet. Has anybody ever heard about this or is this just nonsense?

The tap water in the Netherlands is in the top of the world so I really can't imagine crustaceans in my showerhead unless someone put them there.
The presence of crustaceans has nothing to do with cleanliness. New York City also has famously good water, and it has crustaceans: http://www.nytimes.com/2004/11/07/nyregion/the-waters-fine-b...
That's pretty fascinating. Basically, no one has actually been able to keep true Kosher until the advent of water filters and microscopes.
> and microscopes

All microscopic creates are kosher. It must be visible to the naked eye to be non-kosher.

According to Kosher law you are supposed to check your water after drawing it, to make sure it has no insects in it. This is the backstory for the test in Judges 7 BTW.

Now in modern times people expect drinking water to be clean. So it was quite a surprise to find visible insects in New York water.

> All microscopic creates are kosher.

That seems like an after-the-fact retcon, given folks thousands of years ago being unaware of a microscopic world's existence.

New York City also has famously good water

Not true! NYC does not have "famously good water". I found that out when I had to change my counter-top water filter after about one year of use.

It was more than gross. Imagine having to drink that water without the benefit of a water filter. By the way, I don't think water people drink in many restaurants are filtered.

But couldn't that just be the pipes in your building? The water comes from the Catskills, and when it leaves there, at least, it's extremely clean.
The water towers on top of NYC buildings tend to not be maintained especially well:

  With their quaint barrel-like contours and weathered 
  cedar-plank sides, rooftop water towers are a constant on 
  the New York City skyline. And though they may look like 
  relics of a past age, millions of residents get their 
  drinking water from the tanks every day.

  But inside these rustic-looking vessels, there are often 
  thick layers of muddy sediment. Many have not been 
  cleaned or inspected in years. And regulations governing 
  water tanks are rarely enforced, an examination by The 
  New York Times shows.

That the water at the source is clean may be true, but you judge the water by its nature at the final destination, because in the final analysis, that is where the grade of quality matters to those who'll be drinking it.
The water sources to NYC are very high quality.

Anyway, all water filters get very funky after a year.

True, "all water filters get very funky after a year", that funkiness is an indication of the true quality of the water that reaches your house or apartment.

That's how you tell what you'd have been drinking without filtration.

You seem really bothered by this. What did you see in your filter after a year? Some tiny amount of algae? Some mineral deposits? Do you prefer your water taste like a chlorinated pool?

Wait until you find out what's in your food!

"more than gross" is hardly a scientific analysis of cleanliness, though I guess in line with this article (which is why I flagged it).
Did you want me to scientifically analyse my drinking water before I can comment about it on HN?

I'm talking about the water that reaches my faucet, not the one somewhere upstate NY.

> Imagine having to drink that water without the benefit of a water filter.

We don't have to imagine it. Plenty of people do.

Concentrate a year's worth of tiny impurities and you'll wind up a bit of sludge, yes. You'd probably get it even with pure distilled water from dust and microbes in the air.

Chances are you're breathing a lot more nasty in from taxi exhaust and human feces from farts than you're getting from that water.

Why the focus on showerheads only and not water faucets which people drink much more water from rather than bathe?
It's probably the fact that shower heads have so much more surface area for stuff to grow on and live in. One minute it's wet, and then it's drying for the rest of the day. A water faucet is less hospitable to growing gunk.
Hmm; I could see it being the exact opposite. The shower head, by drying out after a single daily use, could be less hospitable to organisms that need moisture. Meanwhile a faucet, used several times throughout the day, has areas which never dry completely.
They're studying human microbiome, not the health impact of drinking different stuff. Anything living in your showerhead is going to get deposited on your skin every day, so it may be a reservoir for your personal microbes, or something that interferes with them.
there's an element of aerosolisation with showerheads, so you might be breathing this stuff in.
Click bait or not, now I have to clean my shower head. Thanks a lot! :(
You can (mostly) sterilize your showerhead if you want.

Turn up your hot water tank to the highest setting (150F) and wait for it to finish heating, then just run straight hot water for about 10 minutes.

It won't kill everything, but it'll kill most things.

It sounds obvious, but this is incredibly dangerous scalding risk if someone else turns on hot water expecting it to be a reasonable temperature while you're doing this. Even if

Much easier to take your fixtures off and bleach/disinfect.

> Much easier to take your fixtures off and bleach/disinfect.

You have a very different definition of "easier" than me.

And I don't know about you, but hot water is HOT, and I never use it directly while expecting not to get burned - I always mix it with cold.

"He suggested that the female reputation for making tastier bread may derive from the fact that the skin on women’s hands is more likely to be colonized by fermentation-friendly lactobacilli from their vaginas."

This is the weirdest thing I've heard in a while and I wonder if there is even a slight possibility that this is true.

As a homebrewer who consumes the end product of microorganism processes, an unexpected infection almost always yields off-flavors that are counted as defects in the beer. That said, there are some beer types that are "spontaneously fermented" by environmental yeasts, that end up with a sour taste as a desirable characteristic, and the rest of the beer flavor profile is crafted to harmonize with it.

I think there is a slight possibility the claim is true, but only for sourdough breads.

Not really what you want to read while eating sourdough toast.
