10 Facts About The Human Body You’d Rather Not Know

10 Facts About The Human Body You'd Rather Not Know 10 SNOT-EATER The average human swallows mucus around twice a minute, even when they’re sleeping at night

So that means about 15 pints of snot are ingested every single day For reference, that’s about 192 teaspoons This might sound gross, but mucus serves a very important purpose When you breathe in air through your nose, it contains lots of tiny things, like dust, dirt, germs, and pollen

If these made it all the way to the lungs, the lungs could get irritated or infected, making it tough to breathe Luckily, snot helps trap it, keeping it in the nose and out of the lungs Whilst we’re on the subject of snot, it's possible that eating your boogers may help your immune system University of Saskatchewan biochemist Scott Napper conducted studies showing that eating boogers is good for teeth and overall health 9

FORESKIN BEAUTY According to the BBC, every 30 seconds a baby boy is circumcised in America But have you ever thought about where all that spare skin goes? Well, to labs mostly It takes a mere 21 days for a postage-stamp sized piece of circumcised human foreskin to be lab-grown into a size large enough to cover three basketball courts Once grown, researchers have found ways to put foreskin to good use in the medical field, for example it can be made into a skin graft for burn victims It’s also used as a key ingredient in a whole variety of beauty products

Many people – including Oprah – are using facial creams made with human foreskin This is because foreskin is full of fibroblasts, or cells that produce collagen Collagen is a protein that holds connective tissue together – and it plays a big part in maintaining smooth, youthful-looking skin 8 SWEATY FEET Most of us have suffered from foot perspiration and odor from time to time, yet for some people, having sweaty feet is a persistent problem

But why does it happen? Well, there are around 250,000 sweat glands in your feet and these glands can excrete as much as a pint of moisture a day The sweat itself isn’t at all smelly, the bad odor is caused by bacteria on the skin that thrive in sweaty conditions The exact cause of persistent odor is unknown but doctors believe it mainly happens due to overactive sweat glands In some cases, the cause can be genetic Possible other causes include stress on the foot sometimes caused by a structural problem, or because the foot is under strain or tired, for example, when you have been standing on your feet all day 7

FART ATTACK The average person produces about half a liter of farts every single day, and even though many women won't admit it, ladies do it just as often as men In fact, studies have proven that when men and women eat the exact same food, women tend to have even smellier gas than men But there’s one place where both men and women cannot control their flatulence: on a plane As a plane climbs ever higher, the air pressure changes and the gas in your abdomen expands, leading to a severely bloated feeling A feeling that most of us deal with by sneakily letting one rip and hoping that other passengers don’t notice

Excessive farting while flying has gotten so bad that airlines now use super smell-absorbent charcoal filters in the air conditioning and are considering placing charcoal in the seats themselves 6 EYELASH INVADERS Did you know that you have animals living on your face? That’s right, thousands of microscopic mites call your eyelashes home, living on old skin cells and the natural oil produced by human hair follicles Don’t worry though, they are usually harmless, although on rare occasions they can cause an allergic reaction in some people Typically the mites grow to a third of a millimeter and are near-transparent, so you are unlikely to see them with the naked eye

But if you put an eyelash hair or eyebrow hair under the microscope you may find them, as they spend most of their time right at the base of the hair where it meets the skin 5 THE NOT-SO-NAKED APE It was Charles Darwin who first taught the public that humans are descended from apes He also wondered why humans have so little hair, considering his findings But technically humans aren’t really hairless at all

Per square centimeter, human skin has as many, if not more hair follicles as that of other great apes The difference is not in the number, but in the fineness of the hair that grows from those follicles These fine human hairs do not perform the same functions of their counterparts in other species- insulation or camouflage- so what are they for? Well this question was addressed by Isabelle Dean and Michael Siva-Jothy of Sheffield University, in a paper in Biology Letters They concluded that humans have fine body hair to serve as an alarm system to protect us from the attentions of hostile insects 4

BELLY BUTTON BACTERIA There’s so much bacteria in your belly button that you could be uniquely identified by the ecosystem of germs you're harboring In 2012, after two years of quite literal navel gazing, US researchers found 2,368 species of bacteria from swabbing the navels of just 60 people, and 1,458 of the species ""may be new to science"" In the same study, one man was found to harbor bacteria that had previously been found only in soil from Japan, despite the fact he’d never been there

Another individual, who hadn't washed in several years, hosted two species of so-called extremophile bacteria that typically thrive in ice caps and thermal vents But don’t worry too much, because these bacteria are rarely harmful to us 3 BROKEN HEART Have you ever gone through a devastating break up or lost someone close to you? Most of us who have done know that it hurts in a way that physical pain cannot compare In some cases, the feelings can become so overwhelming that you might have even felt like you were going to die

This might seem like an overreaction, but it is scientifically possible to die from a broken heart Extreme emotions—including fear and grief—can trigger stress-related heart attacks that are sometimes fatal caused by Broken Heart Syndrome One famous example occurred in 1986 A 44-year-old Massachusetts woman was admitted to the hospital, suffering the classic symptoms of a heart attack But doctors found no evidence of coronary heart disease

Later, they determined that the woman’s “heart attack” was likely brought on by the news that her 17-year-old son had committed suicide Although that was an extreme case, there are many other examples of sudden, stress-induced heart attacks—and not all are related to grief During the Persian Gulf War in 1991, the stress of being a possible Iraqi target caused Israeli heart attack rates to spike dramatically 2 POOP VOMIT It’s depicted in South Park as a hilarious quip, but vomiting poop can actually happen

Fecal vomiting occurs when the bowel is obstructed and the intestines push the waste back up and out of the mouth instead The vomit, however, doesn't actually contain what we recognize as poop, which comes from the colon It contains liquid from the small intestine, ejected upwards with the help of powerful, reverse contractions of muscles in the small intestine and esophagus Although, to those suffering from the condition, this probably won't make them feel any better After all, liquid from the small intestine can be darker in color and doesn't exactly smell nice

In fact, fecal vomiting leaves a distinct odor of feces on the breath and can cause abdominal pain and dehydration 1 OLD PEOPLE SMELL The truth is “old people smell’- while arguably not the kindest way to talk about our elders – is a real thing In a study published in 2012, blindfolded volunteers reliably recognized the aroma of the elderly by sniffing sweat-soaked armpit pads, although they had a much harder time correctly matching pads to the young and middle-aged Interestingly, the smell wasn’t disgusting though

In contrast to the popular notion that old person smell is disagreeable, volunteers in the study rated the odors of the elderly as much less unpleasant and intense than those of the middle-aged and young Combined with earlier research, the new findings suggest that people retain an ability to gauge someone's age based on their odor This talent is thought to be inherited from evolutionary ancestors that might be linked to the ways animals recognize the sick and dying So while it may smell pleasant enough, it’s pretty gross that the degradation of your body has a distinct smell So that’s 10 Facts About The Human Body You'd Rather Not Know, which one of these shocked you most?
