What is heat stroke?
Every year, runners end up in the hospital with heat stroke during events such as (half) marathons or races of 10 to 16 kilometers. In some cases, this leads to lasting health problems or even death. Despite these risks, there is still much unknown about heat stroke— a condition that occurs when the body retains too much heat during physical exertion, causing body temperature to rise above 40°C.
Although heat stroke is often associated with extremely hot summer days, overheating can also occur at lower temperatures. This happens when the body cannot release enough heat. The risk applies to everyone, including young and well-trained runners.
Signs of heat stroke
Possible symptoms of heat stroke during exertion include:
- An extremely warm feeling during the activity
- Headache
- Dizziness or blurred vision
- Loss of coordination, such as difficulty walking or staggering
- Red skin without sweating
- Nausea
Because confusion and reduced concentration are common, it can be difficult to recognize heat stroke in yourself. Overheating can be severe and even life-threatening, so it is crucial that someone who is overheating receives immediate help. If you notice that a runner is not responding well or is deteriorating, act immediately or call for help.
