Avoid going outside during the hottest days, and avoid vigorous activity and exercise if possible to prevent heat stroke.
Direct exposure to sunlight should be minimized and drinking plenty of water can also reduce the risk of heat stroke. Also, try to stay in the shade when you go out.
Healthy people should avoid caffeinated drinks and sweets or tea, as they can increase dehydration.
In hot weather, eating salty foods and using an umbrella, covering the head, wearing light-colored clothing, and bathing can also help.
