What's the weather like in Guangzhou these days? It's too humid. The house and walls are all soda. I can't do it for several days, and I feel terrible.

This is a unique resurgence phenomenon in the south.

Reasons: the outdoor air is warm and humid, and the indoor air is lower than the outdoor temperature; When warm and humid outdoor air enters the room, the water vapor in the air condenses and adheres to walls, electrical appliances or other indoor objects, forming many small water droplets, and indoor moisture regain will occur.

Solution:

1. Avoid or reduce opening doors and windows to prevent air convection. Many people don't know the reason for the resurgence, thinking that opening doors and windows can make indoor moisture evaporate. In fact, opening doors and windows will only aggravate indoor moisture regain.

2. Turn on the dehumidifier (air conditioning dehumidification function is also available).

3. Mop the floor several times with a dry mop and wipe the wall several times with a dry rag (note: it must be dry).

4. buy some desiccant and put it in several places at home.
