Sweat comes from special parts in our skin called glands. You might be able to see them if you have a very strong magnifying glass.
Tennis Australia recommends suspending play when the “wet bulb globe temperature”, which accounts for sun, air temperature and humidity, exceeds 34°C.
It seems obvious that a game should be suspended if it's too hot to play, but it's not as easy as implementing a maximum temperature.
Sweat creates evaporative cooling for your body, with the amount required determined by your size and shape, not your gender.
They say 'men sweat, while women glow'. But new research shows gender is not the reason for different levels of sweating.
Refreshing – or a sentence to sweat?
Here's the science.
Per litre of sweat produced, we can dump around half a million calories of heat from our bodies.
Our success as a species is 5% inspiration and 95% perspiration.
Blood is just one of the body fluids we need to survive.

By learning a bit more about these body fluids, we can develop a deeper appreciation for the beauty and complexity of our own biology.
Hyperhidrosis or excessive sweating affects around 3% of the population.
Everybody sweats, some more than others. It’s a physiological reaction to heat and the body’s mechanism to regulate core temperate. Individual sweat rates vary and are influenced by factors such as ambient…
