Experts suggest that people should limit going out in the sun in hot weather. Especially between 10 a.m. and 4 p.m. (depending on your country).

Those who are in air-conditioned rooms should not go out suddenly, but need a period of time to adapt themselves to the outdoor environment, such as increasing the temperature of the indoor air conditioner, or sitting in the shade to rest before going out.

Wear brightly colored, breathable, sweaty clothes.

You can eat more vegetables and fruits. If you don’t particularly hate soup, drink it once a day.

You need to take in and drink enough water, and on average at different times of the day, rather than drinking too much at once.

Training your body can strengthen your resistance and endurance.

Apply sunscreen before the sun goes down, and pay attention to choosing healthy products without side effects.
