Getting overheated in summer can have serious consequences, such as getting a heat stroke. Danger signs and symptoms to recognize include high temperature (>40⁰C), irritability, confusion, bizarre behaviour, seizure and coma etc. This is a truly life-threatening emergency. If you suspect someone to be suffering from a heat stroke, call 911 right away. In the meantime, remove the affected person from the sun, remove some clothing, and spray cool water over most of the person’s body surface while waiting for help to arrive.
