Top 10 Amazing Facts About Your Body Odor
- Sweat Does Not Smell
Body odor does not come from sweat itself because sweat is odorless. Your body produces two types of sweat: the eccrine sweat and apocrine sweat. The eccrine sweat represents a clear sweat, consisting mostly of water that does not smell and plays an important role in regulating our body temperature. The apocrine sweat that is produced by the glands is thicker and is located mainly near hair follicles, on the groin area, in the armpits and on the scalp. When bacteria contacts with apocrine sweat on the surface of the skin, the release of chemicals produces your body odor. - Your Body Odor May Indicate a Health Problem
Everyone has its individual body odor, but some types of smell may reveal certain health problems. It is known that if your sweat smells like bleach, it may indicate a kidney or liver disease, while fruity body odor often points to diabetes. Also a rare genetic disorder, called trimethylaminuria, makes a person produce fish-like body odor. - Men's Body Odor is a Turn-on for Women
Researchers at the University of California, Berkeley, discovered that a compound found in male sweat can cause a number of emotional and physiological changes in women. The male chemical androstadienone in sweat was found to regulate menstrual cycle and increase the release of luteinizing hormone, which plays an important role in stimulating ovulation. The male underarm odor also activates certain brain areas, improving woman's mood and sexual arousal. - Men and Women Choose Partners by Odor
If you do not like your new partner's body odor, you may think twice before having long-term relationships with him or her. Scientists say that body odor is a significant factor in human sexual attraction. Men and women choose partners through their body odor and are attracted to partners with a different immune system to their own. This probably has an evolutionary benefit of maintaining diverse immune system for their children. - Your Body Odor Tells About Your Diet
Spicy foods like garlic, onion, curry and cumin contain compounds that can remain in sweat. If you ate large amount of these foods, the strong body odor they give can persist up to 24 hours after eating them. - Women Smell like Onions while Men Smell like Cheese
A curious study conducted by researchers at Firmenich, a company in Geneva revealed that women's body odor contained high levels of sulphur compound, which together with bacteria, feeding on sweat, produces chemical compound thiol that has a smell of onion. According to their findings, men's sweat was found to contain high levels of fatty acid, which when mixed with bacteria from the underarm, produces the smell, resembling cheese. - Asian People Produce Less Body Odor
Excessive sweating is a more common problem for Caucasians and Africans, who tend to have more hair follicles, where apocrine glands come from. East Asian people appear to have less and smaller apocrine glands, which explains why they might not need to use deodorants as often as populations of Africa and Europe. - Your Body Odor is Unique as Fingerprint
Your body produces one of its kind odor, irrespective of what you eat. Individual odortypes are genetically determined odors of each person, containing volatile organic compounds (VOCs) that give you an odor different from others, just like fingerprints or DNA sample. Scientists are working at creating special devices to identify individual odortypes to find criminals, terrorists or missing children. - Kids Do Not Stink
Smelly armpits are not a problem for kids. Normally children do not need to mask their body odor until puberty. The pungent body odor appears when a child enters adolescence between the ages 8 to 14 years. During puberty, the androgen hormones activate sweat glands, leading to production of body odor. - Women Detect Body Odors Better than Men
Women are better at recognizing body odors and appear to identify differences in odor quality. Scientists from the Monell Center say that it is easy for women to sniff out underarm odor even if it is masked with antiperspirants. Researchers claim that women's sensitivity to body odor is explained by its biological importance.
Facts about Farts
Where does fart gas come from?
The gas in our intestines comes from several sources: air we swallow, gas seeping into our intestines from our blood, gas produced by chemical reactions in our guts, and gas produced by bacteria living in our guts.What is fart gas made of?
The composition of fart gas is highly variable.Most of the air we swallow, especially the oxygen component, is absorbed by the body before the gas gets into the intestines. By the time the air reaches the large intestine, most of what is left is nitrogen. Chemical reactions between stomach acid and intestinal fluids may produce carbon dioxide, which is also a component of air and a product of bacterial action. Bacteria also produce hydrogen and methane.
But the relative proportions of these gases that emerge from our anal opening depend on several factors: what we ate, how much air we swallowed, what kinds of bacteria we have in our intestines, and how long we hold in the fart.
The longer a fart is held in, the larger the proportion of inert nitrogen it contains, because the other gases tend to be absorbed into the bloodstream through the walls of the intestine.
A nervous person who swallows a lot of air and who moves stuff through his digestive system rapidly may have a lot of oxygen in his farts, because his body didn't have time to absorb the oxygen.
According to Dr. James L. A. Roth, the author of Gastrointestinal Gas (Ch. 17 in Gastroenterology, v. 4, 1976) most people (2/3 of adults) pass farts that contain no methane. If both parents are methane producers, their children have a 95% chance of being producers as well. The reason for this is apparently unknown. Some researchers suspect a genetic influence, whereas others think the ability is due to environmental factors. However, all methane in any farts comes from bacterial action and not from human cells.
What makes farts stink?
The odor of farts comes from small amounts of hydrogen sulfide gas and mercaptans in the mixture. These compounds contain sulfur. Nitrogen-rich compounds such as skatole and indole also add to the stench of farts. The more sulfur-rich your diet, the more sulfides and mercaptans will be produced by the bacteria in your guts, and the more your farts will stink. Foods such as cauliflower, eggs and meat are notorious for producing smelly farts, whereas beans produce large amounts of not particularly stinky farts.Why do farts make noise?
The sounds are produced by vibrations of the anal opening. Sounds depend on the velocity of expulsion of the gas and the tightness of the sphincter muscles of the anus. Contrary to a popular misconception, fart noise is not generated by the flapping of the butt cheeks. You can see proof of this in the close-up video footage of Carl Plant's fart on Mate-in-a-State .Why are stinky farts generally warmer and quieter than regular farts?
(Question submitted by many, many people!) Most fart gas comes from swallowed air and consists largely of nitrogen and carbon dioxide, the oxygen having been absorbed by the time it reaches the anal opening. These gases are odorless, although they often pick up other (and more odiferous) components on the way through the bowel. They emerge from the anus in fairly large bubbles at body temperature. A person can often achieve a good sound with these voluminous farts, but they are commonly (but not always!) mundane with respect to odor, and don't feel particularly warm.
Another major source of fart gas is bacterial action. Bacterial fermentation and digestion processes produce heat as a byproduct as well as various pungent gases. The resulting bubbles of gas tend to be small, hot, and concentrated with stinky bacterial metabolic products. These emerge as the notorious, warm, SBD (Silent-But-Deadly), often in amounts too small to produce a good sound, but excelling in stench.
How much gas does a normal person pass per day?
On average, a person produces about half a liter of fart gas per day, distributed over an average of about fourteen daily farts.Whereas it may be difficult for you to determine your daily flatus volume, you can certainly keep track of your daily numerical fart count. You might try this as a science fair project: Keep a journal of everything you eat and a count of your farts. You might make a note of the potency of their odor as well. See if you can discover a relationship between what you eat, how much you fart, and how much they smell.
