Study: Men, Women Sweat Differently

OSAKA, Japan, Oct. 8 (UPI) — Women need to work much harder than men to build up a sweat when exercising, Japanese researchers say.

Scientists at Osaka International University and Kobe University discovered that men on average start perspiring much more quickly than women and then twice as much when they are in the middle of exercising, Britain’s Daily Telegraph reported Friday.

Men are more efficient at sweating, meaning their bodies are working more effectively, while women required a much higher body temperature before they started losing moisture, the researchers said.

One researcher said there may be an evolutionary reason why men and women have evolved to sweat differently.

“Women generally have less body fluid than men and may become dehydrated more easily,” study coordinator Dr. Yoshimitsu Inoue said.

“Therefore the lower sweat loss in women may be an adaptation strategy that attaches importance to survival in a hot environment, while the higher sweat rate in men may be a strategy for greater efficiency of action or labor.”
