According to Japanese researchers, men are more efficient at sweating, while women who aren’t used to physical exercise have the worst sweating response, which could mean women suffer more in hot temperatures (sweating helps the body cope with heat). In the study, researchers asked 37 people to cycle continuously for an hour in a controlled climate; intensity intervals were increased. Participants were grouped into four categories: trained and untrained females, trained and untrained males. The rate at which they produced sweat was measured. Physical training boosts sweating in women and men, but more so in the latter, they said. It’s known to help the body perform longer while exercising.
