Let’s talk about sweat

Is sweating a good indicator of a healthy workout? According to David Jenkins, exercise physiologist, it’s not that easy - there are several factors that determine whether you sweat.

To begin with sweat glands are all over our body and they help us to maintain a regular body temperature. These glands secrete sweat onto the surface of our skin when we get hot and as the sweat evaporates we cool down.

For many years we have been told you need to sweat or you’re not working hard enough but Dr Jenkins says external temperature and humidity levels will affect how much we sweat and how long it stays on our body. Jenkins says the simplest way to tell if you’re doing moderate intensity exercise is to do the ‘talk test’. If you’re exercising but are still able to converse comfortably then this is considered moderate intensity exercise and you need to do this for at least 30 minutes every day to keep yourself healthy.
