Body odour [can be] caused by sweat and bacteria when left too long without showering.
When you exercise, your pores open to drain sweat from your sweat glands. These same pores can become clogged with leftover skin or sweat cells if you don't clean your body right after you sweat a lot. Clogged pores can lead to acne known as “sweat acne,” as well as blackheads and whiteheads.
All that sweat from your workout will cause bacteria and yeast to build up, so if you don't shower, you don't rinse those bugs off and may have an increased risk of irritation and infection, Deirdre Hooper, M.D., a dermatologist at Audubon Dermatology in New Orleans, LA, previously told Shape.
Post-workout cleansing is a must to wash away sweat, stink, and blemish-causing bacteria. When you can't shower, wipes are the next best thing.
Unsurprisingly, a person would develop quite a funk after 365 showerless days. Rokhsar said your stench likely would come as a result of the bacteria and dead skin accumulating on you. After a year, he said, you'd have a build-up of skin stratum corneum, or dead skin on top of your skin.
Showering destroys these happy bacterial colonies; they're completely wiped out by all of our frequent rubbing and scrubbing. And when the bacteria washed off by soap repopulate, they tend to favour microbes which produce an odor – yes, too-frequent showering may actually make you smell more.
Hair is another place where bacteria like to hide. If you still smell a strong body odor after a shower, consider shaving the hair in your armpits, groin, and chest. The hair's surface is a perfect place for bacteria to call home, and it's harder to eliminate them from the hair than your bare skin.
If you're worried you're one of these people, one trick is to lick your wrist, wait ten seconds, then sniff the patch you licked: If it smells, chances are, so does your breath. An even more reliable method, of course, is simply to ask someone.
Ideally, once you stop sweating profusely-- in about 20-30 minutes--you can go right ahead with your shower. Tip: While it may feel really frustrating to wait, you can use this time to rehydrate your body, by drinking lots of water or juice.
It would be amazing if you could sniff yourself and immediately pick up on any emanating odors, but alas, life isn't so simple. According to Lifehacker, it can be quite difficult to detect your own body odors because the receptors in your nose shut down after smelling the same scent for too long.
ODOR AFTER A SHOWER IS DUE TO LINGERING BACTERIA
In addition to bacteria, oftentimes there is deodorant residue and other impurities that are trapped in the underarm pores and within the hair if you have armpit hair.
Use scented body wash and lotion.
Using scented body washes whenever you give yourself a sponge bath, and scented lotions after you wash up, is a great way to stay smelling good for longer. Rub your entire body with a scented lotion after you dry off, and carry scented lotion with you to reapply throughout the day.
Great Britain has the lowest rate of showering per week, at 83 percent. However, the English do love their baths: they have the most baths out of every country, with 32 percent of people bathing each week. Germany comes at a far second, at just 20 percent.
Putrefaction (4-10 days after death) – Autolysis occurs and gases (odor) and discoloration starts.
“If you're a heavy sweater, then a good rinse is great to remove the excess sweat,” says Lopez. “Too much sweat can give the hair a dry appearance.” That said, if your hair isn't drenched in sweat (think: you did pilates, yoga or lifted weights), then it's totally OK to forgo washing your hair.
While there is no ideal frequency, experts suggest that showering several times per week is plenty for most people (unless you are grimy, sweaty, or have other reasons to shower more often). Short showers (lasting three or four minutes) with a focus on the armpits and groin may suffice.
So, when you are sweating, your body is still in the process of controlling the body temperature. At this point, it is not recommended to take a shower as it causes a sudden change in body temperature [3], which is not good for your overall health.
"Sweat and sebum help to facilitate detoxification, which is good, but when these toxins reach the surface and aren't cleansed away, they'll reabsorb back into the skin." "When these toxins reach the surface and aren't cleansed away, they'll reabsorb back into the skin."
Allowing sweat to dry on the skin can clog pores and cause acne. Dorf explains that sweating is a necessary way for your body to release toxins. With your system detoxified, your skin will be brighter and healthier -- this is one of the reasons spas use steam treatments.
