1.Sweat Does Not Smell
Body odour 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 odour.

2.Your Body Odour May Indicate a Health Problem
Everyone has its individual body odour, but some types of smell may reveal certain health problems. It is known that if your sweat smells like bleach, it may indicate akidney or liver disease, while fruity body odour often points todiabetes. Also a rare genetic disorder, called trimethylaminuria, makes a person produce fish-like body odour.

3.Men's Body Odour is a Turn-on for Women
Researchersat 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 androstadienonein 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 odour also activates certain brain areas, improving woman's mood and sexual arousal.

4.Men and Women Choose Partners by Odour
If you do not like your new partner's body odour, you may think twice before having long-term relationships with him or her. Scientists say that body odour is a significantfactor in human sexual attraction. Men and women choose partners through their body odour and are attracted to partners with a different immune systemto their own. This probably has an evolutionary benefit of maintaining diverse immune system for their children.

5.Your Body Odour 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 odour they give can persist up to 24 hours after eating them.

6.Women Smell like Onions while Men Smell like Cheese
A curious study conducted by researchers at Firmenich, a company in Genevarevealed that women's body odour 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 containhigh levels of fatty acid, which when mixed with bacteria from the underarm, produces the smell, resembling cheese.

7.Asian People Produce Less Body Odour
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.

8.Your Body Odour is Unique as Fingerprint
Your body produces one of its kind odour, irrespective of what you eat. Individual odour types are genetically determined odours of each person, containing volatile organic compounds(VOCs) that give you an odour different from others, just like fingerprints or DNA sample. Scientists are working at creating special devices to identify individual odour types to find criminals, terrorists or missing children.

9.Kids Do Not Stink
Smelly armpits are not a problem for kids. Normally children do not need to mask their body odour until puberty. The pungent body odour 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 odour.

10.Women Detect Body Odours Better than Men
Women are better at recognizing body odours and appear to identify differences in odour quality. Scientists from the Monell Centersay that it is easy for women to sniff out under arm odour even if it is masked with antiperspirants. Researchers claim that women's sensitivity to body odour is explained by its biological importance.
