Sweating is a very natural function to regulate body temperature. The human body has two to four million sweat glands under the skin. It is often claimed that men sweat more than women. Is this really true?
A natural process
Sweating is a natural process that performs various functions. On the one hand, excess heat is released during sweating and the temperature is regulated. On the other hand, sweat has a signaling effect on the smell. For example, an international research team has concluded in a study that welding odors can make other people happy because of certain chemical substances. Most people would rather share the opinion that sweat smells unpleasant.
Various causes of sweating
Most sweat glands are located on palms, soles, and armpits, which explains why many people complain about sweat or wet hands.
Even with nervousness, stage fright or anxiety, we start to sweat. In addition, hormonal factors, dietary habits or disorders affect sweating.
Often it is claimed that men sweat more than women. Australian researchers now report that this is not the case.
Men sweat no more than women
A study by researchers at the University of Wollongong( UOW) in Australia and colleagues from the Mie Prefectural College of Nursing in Japan showed that women sweat as much as men.
According to the research published in the journal "Experimental Physiology", the amount of perspiration is dependent on body size and not sex. Large people sweat more than small.
"We know that all objects lose heat through their surfaces," co-authored Professor Nigel Taylor in a statement from the Australian University.
"If you compare a metal plate and a ball of equal mass, both heated to the same temperature, the plate will cool down much faster when it is placed in cool air because it has a larger area."
The same principleaccording to scientists, is also for people. Smaller persons have more surface area per kilogram of body mass than larger people and can cool down more efficiently by increasing the blood flow - the heat - on the skin surface. Larger people need to sweat more to achieve the same cooling effect.
Body size comes at
In order to reach their results, the research team around Sean Notley has left 36 men and 24 women in the lab twice cycling for 28 minutes at a room temperature of 28 degrees and a relative humidity of 36 percent while their body functions measuredwere.
It is apparent that men and women could regulate their body warmth alike. At the rate of perspiration, there were hardly any gender differences in this experiment.
"We found that less than five percent of the differences in heat loss between men and women could be explained by their sex," says Taylor.
women are on average smaller than men, so an average big woman is likely to sweat less than an average big man."But that is due to their size and not to their gender," says the University's statement.(ad)
