In the late 1980s a new idea surfaced called the "hygiene hypothesis". According to this new idea, early exposure to certain bacteria is extremely beneficial to the developing immune system of a child.

If my food fall on a not too dirty ground, I eat it, I don't wash my hands every single time I touch something dirty/pets, I walk barefoot and guess what ? It's been almost 8 years since i've been sick and I think it's cause my immune system is well trained.
Since being diagnosed with Ulcerative Colitis and possibly severe case of it, I've had skin rashes that would only heal with use of steroids. After becoming majorly depressed I moved home and haven't gone out pretty much at all, but in my depression I slowed my washing schedule down greatly. Suddenly I noticed that reducing my number of showers(used to be daily) my skin has been able to heal better.
You can put lots of herbs in your home; eating/drinking the tea of the herbs prevent cancer, depression, allergies, the leaves eat dust from the air, you can bury food scraps inside the potting soil to make more soil which after a while will go into the air helping your immune system.
IMO, most of our modern hygiene habits are all due just to product marketing. You see toothbrushes with a kilo of toothpaste on TV, but you need just a 1/10 of that to effectively clean your teeth. And Im not even going to mention how the shampoo industry has made women use like 19 different products to wash their hairs. Or anti-bacterial soaps which make kids get sick with higher frecuency because they kill all the bacteria which would be used to train their inmune systems, etc. Please stop watching TV guys, read and watch youtube instead (:
I think it does. I used to shower twice per day and wash my hands so much they bled lol, and I got sick ALL the TIME. It was frustrating. When one cold was gone another one would start up. Now, I shower twice per week, and I haven't got sick in like ...4 years. I found if you make yourself too sterile it makes there like no shield for the bad bacteria. You literally kill off your first line of defense if you shower too much and you make yourself weak. Sometimes I think that soap companies know this....so you will keep buying soap to clean away the constant colds xD
It should be noted that it's not only hot water which removes the sebum, soap does the same thing, and both deplete the good bacteria which take 24 hours to rebuild their population. Shower with cool water, i.e. body temperature or lower, and only use soap daily on 3 areas--underarms, groin, and the gluteal fold (and maybe feet). Other than that, water pressure and manual agitation will remove the days' accumulation of bacterial waste products (which is what actually causes odor) and dried perspiration, and that only takes about five minutes. Use soap on your whole body only when needed, generally about once a week.
I am 22, haven't been sick since the age of 8. A singular sneeze or cough here or there, but that is everything. I have a strong immune system~
I grew up running bare footed, playing with dirt, and having many pets throughout my life. I have hay fever and intense allergies to many things, including cats and dogs. Bad luck for me, I guess.

Thank you! I've always been annoyed by germaphobes (like my dad), who constantly wash themselves and use antibacterial soaps. The only times I am wary of germs is when I handle raw meats or gross rotten foods etc. My immune system is fantastic, and I have very few problems with allergies...

You said it's anecdotal, not fact that you're less likely to be ill than a lot of folks who didn't play in the dirt. A dear friend told me, after I had my first child, "Every kids going to eat a pound of dirt." Now that country wisdom that seems to have a balance in fact. I ran around in bare feet, I played in dirt and as a child, I had major asthma and many infections, mostly upper respiratory. As an adult, I rarely get sick, but still have to deal with allergens and mild asthma, so maybe I played in the wrong dirt. ;) Anyway, love the series.
I have asthma and allergies; then again my entire family values cleanliness.
When I worked in an assisted living facility they only used anti bacterial soap. We were required to wash our hands constantly. Well I got a rash on my hands and arms due to the anti bacterial soap. Of course it had Triclosan in it. My hands and arms got to be so bad that I had to buy just regular soap to use. I couldn't use hand sanitizer either. I noticed a lot of coworkers calling in and having antibiotic resistant infections. Now that I don't work I refuse to be too clean. I think that the more bacteria and viruses we expose ourselves too, the better. Wouldn't it be awesome to have a sky high immune system so that if we ate some food containing bad bacteria and didn't get sick at all? And we were able to be exposed to Ebola and hepatitis and our immune systems would be able to just fight them off and we wouldn't get sick? And we didn't have to get vaccinated against anything because our immune system fought everything off? I believe that it's highly likely. You know how anti bacterial soap creates super bugs that are resistant to antibiotics? Well I think that we should create an all natural environment that is super resistant to bugs and have super immunity to all bad bacteria and viruses so we'd never get sick. We can make it a reality.
I once drank water out of the gutter when i was a kid lol, im pretty unhygienic and I rarely get sick

What this is really saying We get exposed to bacteria regardless of what We do. We will get sick from the stress alone!

Tracy darling, that Hy Giene! joke.... so bad, srsly, so bad! Great video!
I've been avoiding triclosan for years now. I quit getting sick.... for real
so for those who take it too literally, the subject of antibacteria is meant to understand that anti-B soaps and scrubs should be repeatedly used in place of basic soaps and should not be reapeadedly used. Antibacteria is something to treat areas that need foreign material removed or wounds before treatment.
@AJGoff110

+camron reynosa no, you don't want to use antibacterial soaps for when you just want to remove foreign material. Normal soap is what does that, and it's just the normal soap components and not the antibacterial components that make antibacterial soap clean foreign materials from your skin.

The instance i was trying to refer to is when handling bottly fluids as hospitals have to, or service stores like resturaunts when cleaning human blood from wounds from kitchen work, or cleaning vomit from those who vomit at theme parks or any other situation. there certainly are times where the potential of high consecration bacteria needs to be dealth with where the means to shower or simply wash hands is not enough.

i think this hypothesis is true, i have evidence from my cousin beacause my aunt always overprotected him since he was born, she used to boil the all water that he will drink, he was not able to drink non boiled water until he was like 9 years old and also their house is always extremely clean. So now he is 15 and he is always sick. Meanwhile my neighboor has been really careless with her kids since they were born and those kids are always barefoot walking on the streets and they never get sick
This is an important topic to some extent I agree with you ! well showering once Daily or every two days is fine I grew up as a child playing bare-footed outside yet I still got Sickness but it didn't come from Being less Hygienic or not .. I actually got it from food .. much of our food is injected with all these chemical substances making them last longer or look better or taste better ! but people do not realize that these food are harmful until they take a slap on the face ! like me ... I was once super addicted to Carbonated drinks then I got poisoned and caught a chronic disease so I decided to permenantly stop these drinks so I switched to coffee and tea then i found out that coffee can also Cause the same sickness i have so now i still drink hot drinks like Chamomile and green tea but you need to learn to keep a balance the same thing applies to hygiene you've got to keep a balance ! so that's what i try to do now
So I haven't gotten sick in over a year and I had a water bottle that I didn't wash for over a year also. One day I was about to clean it, and I saw an earwig crawl out of it and bug guts. I think the fact that I didn't wash it could of possibly built up my immune system. Coincidence or not?
i used to play in dirt piles skin my knee and dirt would get in it etc etc and as an adult I never get sick like ever and I see people going round coughing and sneezing spreading disease and sickness and I never catch it
Is it possible for you to add your podcasts to Spotify as well?
Im 19 and have severe OCD towards chemicals. Not germs that much. It sucks and i have complex showering rituals.
If hot showers are bad for the skin, how about hot, long baths? Like in Japan where they have a bathing culture, whether it's public bath houses or traditional hot springs, baths seem to have a super long history. Some hot springs are even advertised to have health benefits and rejuvenating effects on skin and the body in general. Most of it has to be just another marketing ploy, but those natural hot springs with minerals and sulfur and stuff, are they at all good for the skin or overall health? Also, in bath houses, you've got all these baths, and among them are the cold bath and the super hot baths. Some people do this thing where they soak in one, then immediately soak in the other, experiencing a huge jump in temperature. I've heard it can dangerous, but I've tried it, and the tingling sensation is actually rather pleasant once I get my body used to the different baths. I've heard that it might cause shock or stress to the heart or something?... Is it really that bad?... And how about spending hours bathing. Would that be a very bad thing? I usually can't stand it for too long, but when I go to hot springs or bath houses, I wish I could stay in longer, because I find it pleasant and relaxing. Especially seeing those old ladies who seem to spend a good part of the day in the bath, I'm kinda impressed by their bathing rituals. I don't go a lot, but it's one of the things I really like about Japanese culture, but is it bad for the skin to do that too much? Does it strip the skin of too much oil? Are Japanese people just better at soaking?
Very true
I wish I had a dirtier childhood. We would run outside, barefoot with the dogs and all that, but it was always followed by a good daily scrubbing. These days I am less worried about always being "clean". My kitchen is spotless, I wash my hands when preparing food and I will pay extra attention to any sores or scratches so they don't get infected, but I generally only bath 3-4 times a week and these usually coincide with my workout days. Even then its mostly just the important bits that I clean. I also walk barefoot whenever its socially acceptable :P Disgusting? Maybe, Maybe not. I don't care. No one has said I smell which would be my only concern. The only difference I notice is that my knees and elbows are less dry and cracked, which may be related to less cleaning. I get sick less often but I really don't know that is due to the cleaning change since I have made other changes in my life.

Some times go more than a week without showering though I'll normally clean my bits with baby wipes daily and I'm a bit OCD about cleaning my hands and use alcohol gel I know I shouldn't but I get it for free and cleaning my hands 20+ times a day for no real reason is a bit nuts .
One big problem is diet, you should stop eating meat, fish, dairy, oils. If you have a high protein high fat diet your skin will produce too many oils and sweat and your body will just be too smelly. A mostly vegan low protein low fat diet is what your body is designed for and results in much healthier skin and much less acne where you don't need soap. And the dishes in the kitchen become so much easier to wash where you don't need dish soap anymore. As far as clothing detergent, you should just use less for sure and try the more natural detergents but once your body produces less BO then the casual wash really needs very little detergent. The diet really matters.

@YiGzit

no mate, anti-b soap kills the unfit (weak) bacteria so there will be no weak bacteria left to reproduce. Hence why only the fit (strong (fit genes)) bacteria will survive and reproduce. Their DNA will be past on and one of those bacteria might contain a mutated gene to be resistent against anti-b soap.
I developed allergies after being around too many cats... so obviously exposure isn't always preventative. I never use antibacterial soap because when I was a kid, it gave me horrible rashes on my hands. That stuff is nasty. Also, for some reason I really like the way Trace says "soap."

Woah woah woah... watch how you use theory there, bud. Hypothesis and theory are two very different things.
The presenter keeps using "theory" and "hypothesis" interchangeably, but they aren't, there's an important distinction in science. A theory is well-tested and established, from what I can tell he's talking about a hypothesis.

A hypothesis is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. A theory is always backed by evidence; a hypothesis is only a suggested possible outcome, and is testable and falsifiable.
Bacteria don't "breed", they just split apart when it's time for them to multiply. There are no male and female bacteria.

Does hygiene really increase lifespan that much ? I mean, the fact that we have a lifespan that is more than 40 years old is mostly due to the decrease of infantile mortality. So does having a good hygiene really does matter in the increase of our lifespan ?

Please don't misuse hypothesis, theory, and fact. That is one of the worst hurdles for people properly understanding science. "It's not a fact, it is just a theory," is an incorrect way to state something is unknown or not settled. A Theory is an explanation of not only what is happening, but how it is happening that is backed up by all applicable data. A hypothesis is an idea about what is happening, and/or why, that has not yet been proven. It is what guides the development of analysis techniques to find out if it is correct. If enough evidence accumulates to support a hypothesis, it becomes a theory or a law and becomes accepted as a valid explanation of a phenomenon. The difference between a theory and a law is that a law only describes what will happen given certain set variables, without any explanation as to why that may be the case; whereas a theory also explains a bit as to why it happens. Newton's laws of gravity (only actually correct in very specific applications) explain how gravity works in the sense that we experience it (an apple falls to the ground with a certain acceleration that is due to comparative mass and distance to/from the earth, coming out to roughly 9.8m/s^2), whereas Einstein's theories on relativity (both general and special) add up to (among other things) explain how gravity actually is a function of the warping of space time, between objects, and therefore also has other considerations, such as relative velocity, to consider. For all practical purposes, to the extent that we are able to analyze them, theories and laws are about as factually proven as science can allow. If they are shown false by new information, they discontinue being theories and laws, and are eventually replaced by new hypothesis that account for the new information, that are then tested until they are either replaced themselves or they become new theories or laws.

If she doesn't work in healthcare, have you guys considered taking her to see a psychiatrist? Washing your hands to that point is many times a sign of OCD.

You believe that a comment gives a clear insight into somebodies psychology?

Verbux It's not a clear insight into anything, but something's usually wrong if someone's washing their hands to the point of pain.Pain typically makes people adverse to whatever caused the pain.

Have you ever thought that your body is so greasy and oily because it makes up for you constantly washing it off?
Yes it is.

So fucking true. Weird story but when I went to India, I began to puke and my body could not tolerate the bacteria. BUT, later I felt even healthier and better after my body adapted to the bacteria.
You can't classified bacteria as bad and good, because it isn't right. There is only pathogenic and non pathogenic bacteria. And I miss that you aren't mentioning molds and yeasts that live on our bodies too. So you can call them together as microbiota (microbes that lives on our body).
picking your nose?
