First of all, look at the orientation of the house. The north-south orientation is very comfortable. East and west face the sun that rises in the morning and sets slowly at night, so it will be very hot all day.

Then, install a device that can introduce fresh air into the window, so that the indoor atmospheric pressure is higher than the outdoor average atmospheric pressure, and at the same time increase the working time of the exhaust fan of the range hood in the bathroom or kitchen, so that the atmospheric pressure in the bathroom or kitchen is lower than the outdoor average atmospheric pressure, so that the air flows from the room to the bathroom or kitchen, thus meeting the indoor ventilation requirements.

Finally, the method of heat dissipation:

1. Mopping the floor often absorbs heat and makes the house clean.

2. Open all the windows for ventilation.

3. Buy an electric fan or air conditioner

Step 4 tidy up the things in the room

Take out things that are not commonly used and make the room empty.
