Symptoms of Heat-Related Illness

Excessive sweating is one of the first signs of heat-related illness, especially during physical activity.

Feeling unusually weak, tired, or exhausted can indicate your body is struggling to cope with the heat.

A throbbing headache can occur as a result of prolonged exposure to high temperatures.

Feeling sick to your stomach or vomiting can be signs of heat exhaustion or heat stroke.

Painful muscle spasms, particularly in the legs or abdomen, can occur during or after exertion in the heat.

A fast and strong pulse may indicate that your body is working hard to cool down.
