If you know these few common sense, you will no longer be afraid of hot weather.

1. Which is better, fan or air conditioner? What is the most suitable air conditioner temperature? Air conditioning will quickly lower the indoor temperature, thereby making people feel comfortable. However, air conditioning will affect people's normal perspiration function, which will reduce people's ability to regulate temperature and central adjustment ability, causing various discomforts. The temperature of the air conditioner should not be lower than 26 degrees, and the temperature difference between indoor and outdoor should not exceed 7 degrees. In addition, indoor ventilation should be maintained.

Therefore, the editor suggests that it is best to use a fan. In addition, do not blow the air conditioner or fan directly at people at night. This can easily cause people to squint their eyes and cause facial paralysis.

2. What is the best way to protect yourself from the sun?

My friend joked: Don’t fall when you go out, as you may get burned easily! The fiery sun does not know how to be "reserved" like the moon, especially in the summer of July. But we still have to go out, so what is the most effective way to protect yourself from the sun?

There are traditional sun protection tools on the market, such as: sun protection clothing, sun hats, sunscreen, sunscreen spray, sun umbrellas, etc. Of course, these are very safe and effective ways to protect yourself from the sun. If you want to avoid getting tanned by the hot sun, try to go out between 6:00-11:00 in the morning and 16:00-21:00 in the afternoon. In addition, try to choose light-colored cotton clothes that are loose and loose. The reasons are: cotton materials can absorb discharged sweat and quickly take away the heat in the body; loose clothes can allow sweat to leave the body surface quickly; light-colored clothes absorb less heat and are more durable. Dark colors are more suitable for summer.

3. The temperature remains high, so pay attention to safety when charging your mobile phone

Many friends like to charge while playing with their mobile phones, especially before going to bed. In the hot summer, the temperature of the mobile phone will be relatively high. If you play while charging, the heat generated during the operation of the mobile phone plus the heat generated by the battery charging will be hotter than usual. This not only harms the body, but also greatly reduces the service life of the mobile phone. Therefore, the editor recommends that you do not use your mobile phone in high temperature environments.

4. How to escape if you encounter a fire?

In high-rise buildings, if you encounter a fire, you should immediately call the fire hotline: 119 and tell the location, fire floor, fire intensity and other information so that firefighters can arrive at the fire scene in time.

When you are on the lower floor of the fire floor, you should find the fire escape as soon as possible and run down. Never take the elevator! When you are on the upper floor of the fire floor and the fire is relatively strong, do not think about rushing down. Cover your mouth and nose with a wet towel first, then quickly run to a room on the upper floor with a window, water, and near the main road. Close the door and open the door. Broken glass, waving colorful things to attract attention. If it is at night, turn on the flashlight to attract attention and get help. Don't choose to jump easily.
