Extended data:
High humidity in winter will accelerate heat conduction and make people feel cold. When the indoor humidity is too low, people will feel thirsty, even sore throat and nosebleeds. And it is easy to catch a cold because of the large loss of water in the upper respiratory mucosa. In summer, the indoor humidity is too high, which will inhibit the heat dissipation of the human body and make people feel very stuffy and irritable.
For people who need to go out frequently, if the room temperature is too high, the temperature difference between indoor and outdoor will increase, which will reduce their resistance, make the indoor air unusually dry, destroy the warm and humid environment in the body, and affect the secretion of body fluids, which will not only make people feel hot and dry, but also make people feel difficult to breathe, and the eyes, ears, eyes, mouth, nose, throat and skin are unusually dry.
If the indoor temperature is too low, the metabolic function of human body will be reduced, pulse breathing will slow down, subcutaneous blood vessels will contract, skin will be excessively tense, and respiratory resistance will be weakened, which will easily induce respiratory diseases. Remind friends to properly open the window and ventilate to ensure the comfort of living. It is best to put a basin of water indoors or use a humidifier to increase indoor humidity.
