Why is it so hot at midnight?

1. The room is too small, the weather is too hot and the air is not circulating.

2. You are asleep, your organs are still working, and it is detoxification time around 3 am.

3. it has nothing to do with feng shui. Many people have been woken up by the heat this year, especially those with blood fever.

It is recommended that the meeting window be ventilated before going to bed. Of course, open the window with the air conditioner for 20 minutes, and then the air conditioner will automatically turn off for half an hour. You should sleep peacefully. It's best not to open the window. Although it is still hot after beginning of autumn, it is still cool in the autumn wind at night. Sleeping with the window open is easy to get wet and catch cold, which is not good for your health.
