1, timely replenish water and balance nutrition.

Drink a small amount of water for many times, each time 100 ml is appropriate. It is not advisable to drink cold drinks during or after strenuous exercise. If you want to spend the summer safely, you should eat as many miscellaneous grains, coarse grains, fruits and vegetables as possible.

2, indoor and outdoor temperature difference should not be too large.

The temperature difference between indoor and outdoor air conditioners should not exceed 5 degrees. Even if the weather is hot again, the indoor temperature of the air conditioner should not be lower than 24 degrees. The room should be kept quiet, clean, ventilated and cool.

It is good to take a nap, but it should not be too long.

Sleepy in summer, it seems a good choice to take a nap in the middle of the afternoon, but many people encounter the embarrassment of "not getting up". Taking a long nap will deepen the inhibition of the central nervous system of the brain and lead to more fatigue after waking up. But you can't stay up late, you must ensure adequate sleep quality.

4. Avoid "rapid cooling" after heating.

When you go out or come back from work in hot summer, avoid turning on the electric fan and taking a cold bath immediately. This will make the pores of the whole body close quickly, but the heat in the body is difficult to dissipate. It will also cause insufficient blood supply to the brain due to the rapid contraction of blood vessels in the brain, which will make people dizzy.

5. Prepare sun protection equipment.

When going out in high temperature, you should take protective measures, such as umbrellas, sun hats and sunglasses. It is best to apply some sunscreen products to minimize outdoor activities.
