Do men sweat more than women? Turns out that, in general, men do sweat more. And, at a faster rate to boot. From an evolutionary perspective, men developed a more efficient way to cool off given that they were more physically active (don't get me wrong here - we are talking way back in time). For example, they were more likely to be outdoors involved in activities such as hunting. Greater exposure to heat and a more active lifestyle helped develop a more efficient means of reducing body temperature when needed.
On the other hand, women tended to be engaged in relatively less physically demanding activities (e.g. rearing of children, etc.) and as a result evolved to sweat less then men. While this may seem more appealing to some, sweating less does come with a few drawbacks. Women tend to be at greater risk of heat stroke or exhaustion. Their smaller body size/surface area along with a less efficient cooling mechanism makes them at greater risk of dehydration.
