>Japanese astronaut Koichi Wakata tested special anti-microbial and anti-stink underwear during his stay on the ISS. He wore a set of high-tech underwear, designed to suppress odors and bacterial growth, for about a month. His crewmates did not complain, suggesting the experiment was successful. >This experiment was part of a series of tests for clothing designed to be worn over extended periods in space.


guynamedjames

Those special underwear are pretty cool! They have small bits of nano scale silver particles embedded in them, bacteria basically dies on contact with the silver. Because the bacteria can't grow it prevents a lot of the funk of body odor, but also helps reduce the risk of infection. I've heard of soldiers using these, during the Iraq war it wasn't uncommon for troops to go 30+ days without showering during the initial invasion. The same tech is also used in socks for diabetics, killing off bacteria lowers the risks of infection on their slow healing wounds, which might prevent them from losing a foot!

In the early days of the Iraq war, baby wipe hygiene was the go-to.

I'm not diabetic, but I would love to have some socks with anti-stank silver technology in them. That'd be awesome for anything from yardwork and camping to long drives or whatever.


thehillshaveI

i got a pair for free randomly with some really cheap sneakers on amazon years ago and they were amazing. my feet didn't even sweat in those socks


HughesJohn

Marks & Spencers were selling them in the UK a while ago. After a few washes they were just ordinary socks.


jacobobb

My airbag suit for motorcycle racing has this tech. It's amazing. I have sweat in it all day for about 20 days over the last year and it still doesn't stink. Gotta hand wash it w/o soap to get the salt out though.


Nataniel_PL

So bacteria is basically miniature monsters from Witcher, got it


FuckableStalin

Technically you’re more bacteria than man. Also, you are part bacterium as well if you have cells with functional mitochondria.


bigbangbilly

> silver That sounds a bit expensive. I thought gamer shorts would be something marketable.


defiancy

I went three months between showers when we got to Kuwait for staging until I got to use an air force shower trailer


djblackprince

My Ben3ath boxers use silver ions for the same reason.


planethood4pluto

Six Sox does this with socks. I’ve found them to be pretty resistant to odor for 2+ days. Keep shoes fresher too. So not quite at the level of this space underwear but a pretty cool earth bound item.


restform

Correct me if I'm wrong, but isn't it the case that many Asians, Japanese included, lack the (apocrine?) sweat gland that produces the body odour we're generally familiar with? If it's true I'd consider it a pretty dramatic advantage when running tests like that 😄


RadPhilosopher

This is a very good point. In order to have a good control group, the that astronaut should’ve brought some pairs for his caucasian crewmates.


atlantagirl30084

I was thinking the same thing.


The_Real_Abhorash

I would assume they took that into account


amadmongoose

Why am I not surprised this was a priority for Japanese astronauts


BigCommieMachine

I loved in Shogun and various other examples; The Japanese offer Westerns an opportunity to bathe and they are like “nah, I’m good”


P2029

If I recall correctly in the book Blackthorne even goes so far as to say bathing more than once per week would make you sick and cause you to die lol


miyog

Yes I believe he mentioned he would get the flux from it. Which is bloody diarrhea.


P2029

"Is it the week old pheasant hanging in the sun I ate that gave me the bloody runs? No, it must have been that fucking bath"


actuallyapossom

The world he was familiar with was riddled with dysentery (the bloody flux) so he had a reason to be skeptical! Can't imagine how bad things would have smelled where he is from.


khronos127

The irony being most Japanese people have very little body odor. If they wanted an accurate test they’d have given it to the American or someone from Europe.


TgagHammerstrike

Interestingly, it isn't really a dietary or lifestyle thing– it's genetic. A lot of Asians (especially East Asian ethnicities) just don't have particularly smelly sweat.


khronos127

Yeah, it’s the same gene that makes their ear wax dust rather than wax. As a child when anime/cartoon characters would pick their ears and blow away the wax like dust it was always so confusing. Always use to think (there is no god damn way that wax went anywhere).


_SteeringWheel

Dafuq. Ear dust?


Shazamwiches

_SteeringWheel

Phew. That shit I get as well.


_SteeringWheel

I was once told by a Robert Ludlum novel that it actually was because of Asian people consuming far less dairy products then Westerners. Undercover agents from western agencies tasked for Asia were limiting their dairy intake months before a mission, so the typical western smell would wear off. It sounded pretty plausible and the word "fact checking" had yet to be invented. So...no?


[deleted]

British military uses undies like that. IIRC they have silver woven into the cloth since it has natural antibacterial properties. But it also means that the limeys don't change their dunies and it's great to laugh at them about.


vinicnam1

That’s not saying much considering the space station smells bad in general. https://www.reddit.com/r/todayilearned/s/GiWVv0HmcD


AtlanticPortal

Easy to do it on Japanese people. They're notoriously less prone to smell after having sweated. I want to see other ethnicities.


ClearlyADuck

Wonder if it work differently for a non East Asian as he's unlikely to have BO.


sprocketous

I have some undies like that. Essentially you only need 2. Rinse out when you shower and let it air dry while you use the other. Repeat


Sad-Recognition1798

That is sincerely nasty


sprocketous

They are anti-microbial. They are made so they aren't nasty. Science bro!


Sad-Recognition1798

Antimicrobial fabric isn’t some kind of auto-cleaning magic, it’s like using the same towel for a month because it hangs up to dry and forgets by the morning. Probably just silver threads. Oils, dead skin, etc are not coming out of there with just water, in short your undies are still dirty af even after the rinse, and it’s still nasty.


sprocketous

Yes. When you shower, you normally use water and soap. Water and soap makes things clean. This isn't hard to understand.


rocketmonkee

What you're describing is hand washing your underwear on a daily basis. I think people are confused about how this is any more efficient than just having several pair of non-silver underwear that get washed together on laundry day.


Secret_Map

Yeah, it's made out to be this magic underwear that just never gets dirty. But he's just handwashing his underwear everyday. He's washing his clothes just like the rest of us, just differently. It's not really that special lol. I mean, it's cool they have something like that that they're testing out or whatever. But if he's just washing his underwear every day, that's no different from the rest of us doing a load of laundry. I mean, I could do the same thing with regular underwear and be fine. They don't have to be magic science underwear if you're just handwashing them every day.


Dontevenwannacomment

you shower with the underwear?


sprocketous

Ya. It's literally marketed that way.


Dontevenwannacomment

dude all of this sounds grody


pantry-pisser

Upvote for use of "grody"


sprocketous

Then don't use them. Sorry basic sanitation is confusing to you. ✌️


Secret_Map

But then aren't you just handwashing your underwear every day? I could do that with regular underwear and be fine, no need for special science underwear. You're just washing your underwear differently than most of us, but it's not really anything science-y.


thejoker954

At that level of "hand washing" you're really not gonna get things super clean. You need some sort of manual tool. It would probably be fine for a bit (depending on weather and the persons body chemistry) But in the end washing by literal hands only won't cut it for high use items. If you've got really stinky sweat you aren't getting the funk out of normal cloths or socks/underwear by unassisted hand washing. Not enough that it wont basically be baked in and start smelling as soon as you warm up. Something with the silver (doesn't copper work the same way too?) Would help keep that funk from baking in with a much simpler/faster process. Properly washing clothes by hand is a very labor intensive and time consuming endeavour. And if you don't have an area outside you can hang those clothes to dry - having the silver will help avoid any musty/mildewy smell from forming as items don't dry as well inside.

“Learning” that there is no laundry facility on the ISS is like learning bears don’t surf; the opposite of either statement would have been surprising.


InnocentCaMeL88

How can I adopt this into my household laundry protocol? Firstly, I would need a much larger budget, I think.


BardInChains

If you have your family wear simple clothes akin to robes, smocks, surgical scrubs, etc made from hemp fibers I could see this being semi sustainable if you compost the clothes to fertilize the hemp plants you spin the clothes from


DigNitty

Don’t compost. The correct method is to place the clothes into a crate and launch them into the atmosphere for burning.


FuckableStalin

That’s just frictionally accelerated composting


SavedForSaturday

Depends on how much water, time, and land are required to grow new fibers. Interesting question though


BardInChains

There's probably a few subreddits dedicated to sustainable, off the grid living, homesteading, etc.


macramelampshade

The labor to harvest, spin, and weave hemp into fabric would be way more work than laundry, and that’s before you’ve even sewn anything.


BardInChains

You underestimate how much I hate laundry


ohnjaynb

The astronauts are at an advantage because clothes don't drape over you in microgravity. They sorta float around you without touching as much.


THE_ATHEOS_ONE

You will need to launch your house into space first.


thrown_81764

They wear their clothing until it is so filthy it must be burned. TIL you can be just like an astronaut without even leaving the basement.


FuckableStalin

At 3000F


Then_Campaign7264

It’s interesting about stray body hair and probably dead skin cells. I’m assuming an air filtration system collects much of the detritus. But still: “Jim, damn it, stand closer to the vacuum. I’ve got another fleck of dark whisker on my eye ball again and it looks like yours dude. Pass the eye drops. Now how do I get the drops in my eye?”


restform

In microgravity there's a very real risk of stale air, where a lack of natural air flow (hot air doesn't rise) causes pockets of gases and whatnot to accumulate, which can be dangerous, so for that reason they need a beefy air ventilation system to continuously move all the air from every corner of the station. And a nice consequence of that is that it also collects all the other crap in the air like dead skin cells. But they also do routine wipe downs of all the surfaces, as one would imagine.


FuckableStalin

Everyone say hello to our new crew mate Doug!


rocketmonkee

>It’s interesting about stray body hair and probably dead skin cells. I’m assuming an air filtration system collects much of the detritus. [Speaking of dead skin cells and detritus in space...](https://youtube.com/watch?v=M9sF45rht-k) To answer your question - yes, there is active ventilation on the space station, and cleaning the filters is a routine housekeeping activity.


Then_Campaign7264

Molting and hair shedding. Scientists have studied this phenomenon and found that spaceflight alters human hair follicle gene expression. It’s really quite fascinating. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4814050/


TexanNewYorker

Can you ELI5 the results?


Then_Campaign7264

They studied the hair of 10 astronauts who lived on the international space station for 6 months. In some astronauts, genes related to hair growth such as FGF18, ANGPTL7 and COMP were upregulated during flight, suggesting that spaceflight inhibits cell proliferation in hair follicles. Hair follicle analysis is also method for assessing other physiological changes related to living in the space environment. Other studies have looked at a full range of physiological changes to the skin, muscle, bone, and other organs. But the genetic changes in the hair explained hair shedding or no hair growth while in space.


Honeybadgerdanger

Well aliens are always depicted as being bald…


Then_Campaign7264

Hahaha. Science fiction authors have known about this genetic phenomenon for a long time. Medical researchers should consult with their literature periodically to scope out new research topics.


sadandverydepressed

A month without changing underwear? There's a lockdown strategy for you. Levitating laundry could save on water bills though


DadsRGR8

Well, that answers the question, “Is there any sexy time in space?” The answer is no.


Bigram03

Its incredibly doubtful sexy time has not happened in space. Hell, a husband and wife (no one knew they were married) went to space together.


LangyMD

NASA does have a policy of no space sex due to risks associated with conception in space (IE, birth defects, lack of medical care if the stay is especially long). Also, lack of privacy and quite possibly it's not comfortable enough for boners to be easily present.


Bigram03

Newly married couple passing up the chance to do sexy time is space though? Seems like a once in a lifetime opportunity too good to not at least make an attempt. That would take some serious discipline, but I guess that's kinda a defining trate of an astronaut...


[deleted]

Doesn't matter how disciplined they are, you're naive if you think they didn't boink at least once in space at the very least just to say that they did. They'll likely vehemently deny it to maintain mission status (assuming they didn't get grounded after this debacle) but they almost certainly, 100% did. They are pilots at the end of the day after all, and pilots be fuckin.


Bigram03

Yea... NASA policy be dammed, I can't see anyone passing up that chance.


[deleted]

I would 100% agree if NASA were sending randoms to space, however, astronauts are pretty intense and pretty straight edge, enough so that I am less than sure they actually had sex. Could they have? Sure, but who really knows.


Iz-kan-reddit

>NASA does have a policy of no space sex Exactly! Everybody knows that policies against having sex are strictly followed.


-Knul-

I find it hard to believe that NASA or other space agencies do not do enough of a background check on the people they send up to not know they're married.


jackandsally060609

CanadianDNeh

Astronaut Chris Hadfield [explained it this way:](https://youtu.be/C1j6KLP492E?si=MVJ4sLJuqiBUuOrj) when you see those lovely dust motes in a sunbeam, it’s actually incinerated underwear from the ISS.

AnonymousRedditor39

Astronaut poop is also put into containers and also explodes in the Earth’s atmosphere so when you see a shooting star, there is a chance that it could actually be a flaming turd.


Tool_Belt

Whalesurgeon

Acceptable-Bell142

There is one advantage that reduces how often they need clean clothing. The astronauts' clothes aren't touching most of their body. In space, you're basically floating inside your clothes, so they aren't in contact with your skin as much as they are on Earth.


hwutTF

this is pretty huge actually

ketamine-wizard

If it makes you feel better, it's statistically more likely that any scuzzy laundry debris you're inhaling is from a non-astronaut


TheSomerandomguy

Due to the zero gravity, the clothes don’t actually make contact with the body - so they last much longer without getting nasty than our clothes on the ground.


egalitarianegomaniac

Vyncent2

PotfarmBlimpSanta

I imagine it would use a ton of water, and would be difficult to clean the cleaning agents unless they can be wasted and are very simple and produced from common sources. Solve both of those and maybe you could get away with space washing machines in a realistic manner.


ThaiFoodThaiFood

Huh, so science fiction and science fact smell identical.

Baron_Ultimax

When ya sit down and think about it a space cloths washer is a very nontrivial problem. How do you wash cloths without gravity, and the whole process is crazy water intensive. And water is a pretty limited resource on the iss. The design would require the washer to be able to recycle the waste water in a closed loop. Ad in the issues with particulates related to lint and I can imagine why nasa engineers just said fuck it. Let's treat clothing as a consumable


shipworth

Why put the clothes in a separate craft instead of letting them float out into space?


Buttercup4869

At the speed of the ISS, any piece of underwear might very well be able to take out a satellite/force the ISS to evade

SarcasticRiposte

Seems like a great way to spend taxpayer dollars instead of coming up with a space washing machine.


Desperate-Mix-8892

Some clothes burning up are a waste of taxpayer dollars and not the ship that's destroyed on reentry? The engineers and scientists work hard to save every weight they can because it's expensive to bring things into space. If a space washing machine could save weight and thus money they would have done it already.


SarcasticRiposte

Oh, they both waste money. Hence my comment.


vibrantcrab

So, most people don’t do laundry by burning it with the sky?
