Volume of body sweat increased in both races with rate of walking; volume of hand sweat increased more in Whites than in Blacks. The Mann-Whitney test revealed that volumes of hand sweat were significantly greater for Whites than for Blacks.

There’s an even more obvious answer: Some people are just dirty. Other explanations for why human beings smell different from each other include hygiene and health. Consider one’s lifestyle. People who are dirtier than others are going to have more bacteria on their bodies — especially if they don’t shower often.

It serves no purpose, except to act as a delicious snack for the bacteria that turn it into the stink in our sweat. That means that our bodies may have evolved to produce chemical precursors, just so the bacteria could gobble them up and make us stink. If true, why would our bodies aid bacteria to make these smells.

Summary: Researchers have demonstrated the existence of an olfactory receptor in pigment-producing cells in human skin, the so-called melanocytes. They have shown that the violet-like scent Beta-Ionone can activate the receptor.

Sweat itself doesn’t smell, but body odor can be the result when skin bacteria breaks down the acids in the sweat.

Interestingly, prepubescent girls and boys sweat about the same volume. But once hormones kick in, sweating starts to vary between the sexes with men tending to begin sweating sooner and in higher volume (with activity or heat) than women.

The most common areas of sweating on the body include:

• armpits.
• face.
• palms of the hands.
• soles of the feet.

Interestingly, feet are usually the sweatiest part of the human body because each foot has approximately 250,000 sweat glands. They can produce up to half a litre of perspiration per day. Plus, they spend a lot of time wrapped in shoes and socks, increasing the amount of sweat they excrete.

Sweat literally leaves your skin glistening, but more importantly, exercise gets blood circulating throughout the body, which gives your skin a healthy glow from the inside out. Proper blood flow allows oxygen and nutrients to circulate and nourish skin cells.

Some people aren’t able to sweat typically because their sweat glands are no longer functioning properly. This condition is known as hypohidrosis, or anhidrosis. It can affect your entire body, a single area, or scattered areas. The inability to sweat can cause overheating.

Ross syndrome is a rare dysautonomia characterized by a clinical complex of segmental anhidrosis or hypohidrosis, areflexia, and tonic pupils. A very few cases (≃50) have been reported in literature since its original description in 1958.

People in great shape can actually sweat more. Your heavy sweating could be a sign that you’re physically fit. Research shows that fit individuals, especially those who train for endurance sports like running and cycling, sweat sooner and more profusely than people who rarely get physical.

Depending on the sweating symptoms, excess perspiration can be caused by anything from low blood sugar to pregnancy to thyroid issues to medication. “Certain conditions, like diabetes, thyroid conditions, and menopause may cause excessive sweating,” Dr.

The easiest way to tackle excessive sweating is with an antiperspirant, which most people already use on a daily basis. Most antiperspirants contain aluminum salts. When you roll them onto your skin, antiperspirants form a plug that blocks perspiration.
