How hot is too hot? Here’s what to consider when exercising in the heat |
If you like to exercise outdoors, summer gives you more chance to catch the daylight. It’s often easier to get out of bed and still light when you finish work.
But what about when it gets really hot?
Regular exercise throughout the year is crucial for maintaining good health. But in summer you might feel yourself sweating more and wonder if it’s actually risky.
So, how hot is too hot? Here’s what to keep in mind when exercising in the heat.
Normally, the body maintains a core temperature around 37°C. But exercising – especially when it’s hot and humid – can put more strain on these processes.

Mild symptoms can include headaches and feeling faint. Severe cases can lead to seizures, loss of consciousness or even death.
