What month does it start to cool down?

The temperature usually drops in September.

Depending on your area, it will be later in the south, earlier in the north after September, and in the middle and late August. Although the temperature rises after the early autumn, the high temperature will last for about half a month due to the influence of the autumn tiger. It is understood that autumn tigers usually occur at the turn of August and September, and the duration is about 7- 15 days.

The reason for the formation of the autumn tiger is that the western Pacific subtropical high, which controls China in autumn, gradually moved southward, but then moved northward. Under the control of this high pressure, the sky is clear and cloudless, the sun is strong and the temperature rises. According to previous years' experience, the solar term that China really started to cool down was the autumnal equinox. At the autumnal equinox, the sun basically reaches the equator and gradually moves south. At this time, the days are short, the nights are long, and the time for sunlight to shine on our country is gradually shortened.

Matters needing attention when the weather turns cold

Please keep enough sleep every day. After a good rest, the body's resistance will be much stronger. We usually take part in sports and just do our best. It is very important to pay attention to adequate sleep. Don't stay up late. When you are tired, you can arrange your time reasonably to ensure that you have enough energy to fight the virus.

The average human body can't accept the frequent alternation of cold and warm. This drastic change will reduce your immunity and make you vulnerable to the flu virus. What you need to do is to observe the temperature changes and add or subtract clothes for yourself. Morning and evening are the coldest time of the day, so pay special attention to them. When you sleep at night, change the quilt a little thicker to ensure that the indoor temperature is 18℃-22℃. In addition, when there is sunshine, try to let it shine into the room, which is helpful for disinfection and sterilization.
