Which is worse, dry heat or wet heat? Both, says an exercise physiologist.
If you’re itching to get back to the gym when it re-opens, here’s what you can do to protect yourself and others from COVID-19.
Sweating is usually our body's way of stopping us from overheating. But if excess sweating is a problem for you, there's help.

In his recent interview, Prince Andrew claimed that he had stopped sweating. Here’s what the research says about how and why our bodies do it.

What is the smell of sweat? An artist recreates the pungent body odor as an art installation.
Exercising in hot weather adds stress to the body and comes with risk of heat exhaustion.
You can stay fit during soaring summer temperatures — if you follow some simple precautions.
For the roughly 3% of people who have this condition, sweating can be almost constant.
When we get hot, sensors in the body tell the brain. The brain then tells the sweat glands to work, and we sweat.
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…
