Is there any simple and practical way to make a cold and humid room warmer?

First, when you say that the house is cold, you mean that the direction of the house is not good, and it is difficult for the sun to shine directly, resulting in a slightly heavy yin and insufficient yang. The temperature will naturally be low.

Second, when you say wet, it means that the house is either poorly ventilated or low-lying, or there is something too wet in the house.

Solution, 1, open a window facing the sun, if not, there is no condition, you can install an electric heater.

2. Pay attention to ventilation. If the external environment is not very humid, keeping ventilation can make the house dry.
