Two, why is it so hot after the volt

1. direct sunlight to the Northern Hemisphere

The earth has been leaned his around the sun, and the day and night hours; the earth revolves around the sun also, so there are four seasons of. By the summer solstice (20 or 21 or 22 days of the Gregorian calendar), the sun will reach the northernmost position of the earth (Tropic of cancer) in June. So the weather will begin to heat up.

2. subtropical high impact

In the subtropical zone of the northern and southern hemisphere, due to the impact of land and sea, the high pressure zone often breaks into several high-pressure monomers, forming a discontinuous high pressure belt along the latitude circle, which is called the subtropical high.

(1) under the influence of the subtropical high, the air flows down and the sunlight hits the ground. With the increase of the ground radiation temperature, the surface heat loss will gradually decrease, and the weather will become hotter.

(2) when the subtropical high controls a region for a long time, it often causes drought in the area. Rainfall is reduced, which is also an important factor in the heat.

Three, after the volt to health

1. refuse to be lazy

Summer is very easy to make people do not want to move feeling, the sun is too strong outside, do not want to go out; eat without appetite; nap, sleep will not think of and so on.

Therefore, even if the weather is sultry, we should also maintain a good state of mind, and give ourselves some recreational activities to relax and relieve anxiety.

3. refused to stay up late for a long time

Throughout the summer, the whole night is shorter than in the daytime, which makes many people develop the habit of sleeping late and getting up early. Of course, compared with other seasons, this is no problem, but it shouldn't be too late. Because when sleeping, the human body needs to secrete hormone, in order to maintain the normal operation of the body, if long-term sleep late, it is easy to cause endocrine disorders.

4. do not Tanliang

When the weather is hot, many people choose to blow air conditioners or eat cold drinks. However, everything should have a degree, this season is the best time for sweating cold, if blindly Tanliang, since the cold winter gathering will be "locked" in the body, it is easy to cause the body cold.

5. prevent moisture

It's easy to rain in summer, and the humidity in the air is great. If you always sleep on the floor, the bath is not dry, after the rain is not timely change clothes, it is easy to make the body moisture accumulation, which can cause edema, indigestion, fattening, listlessness and so on, so we should pay attention to prevention.
