**Winter, temperature is a matter of health**
In winter, your biggest concern may be whether the temperature in your home is enough.
It is important to know that the suitable healthy temperature for the human body is 45%RH~65%RH, while the indoor temperature during the winter heating period is usually 15%RH. In such a dry environment, people will have all kinds of discomfort.
In a dry environment, the resistance of the human respiratory system is reduced, which can easily cause or aggravate respiratory diseases. Practice has proved that when the air humidity is lower than 40%, the cilia movement on the mucous membrane of the respiratory tract of the nose and lungs slows down, and dust, bacteria, etc. are easy to attach to the mucosa, irritate the larynx and cause coughing, and are also prone to other diseases of the respiratory tract.
