Here are the tips for preventing heatstroke and cooling:

1. Replenish water in time but drink less drinks. Beverages contain a lot of saccharin and electrolytes. Drinking too much will cause adverse irritation to the gastrointestinal tract and affect digestion and appetite. Therefore, you should drink more boiled water or lightly salted (sugar) boiled water in summer.

2. The strongest short-wave radiation from the sun is around 10:00-15:00. You should try to avoid going out during this time. It is better to wear light-colored clothes in summer.

3. The diet should not be too light. In summer, people are active for a long time, sweat a lot, and consume a lot of energy. They should eat more nutritious foods such as chicken, duck, lean meat, fish, and eggs to meet the body's metabolic needs.

4. The nap time should not be too long. If you take a nap for too long, the central nervous system will be further inhibited, and the relative reduction of blood flow in the brain will slow down the metabolic process, causing discomfort and drowsiness after waking up.

5. Avoid "rapid cooling" after being heated. In the hot summer, when people go out or return from work, they like to turn on the fan or take a cold shower immediately. This will quickly close the pores in the body and make it difficult for the body's heat to dissipate.
