Effects on physical health

Scientific research shows that indoor humidity in the range of 40%-60% will make people feel comfortable and is beneficial to health. The indoor humidity is related to the local seasonal conditions. For example, the indoor humidity in summer is 30%-60% that will make people comfortable, and the indoor humidity in winter is 30%-80%.

When the humidity cannot meet the needs of the human body, it is easy to induce various physical discomforts, such as nosebleeds, dizziness, dry mouth, cough, etc. Of course, when the humidity in the air is too low or even too high, many bacteria and viruses will breed, thus inducing various respiratory diseases.

Especially for babies, pregnant women, the elderly, and children, because their own resistance is weaker than other people, the resistance of the respiratory mucosal barrier is relatively poor, and an environment with too low temperature and humidity will further weaken the respiratory barrier function, making it easier for pathogenic microorganisms and bacteria in the air to invade, thereby inducing respiratory diseases.

There are also rhinitis patients, who have certain requirements for air quality. During the pollen season or smelling various odors in the air, it is easy to induce sneezing and runny noses.

When the air humidity is relatively low, dust and bacteria can easily float in the air.

When the humidity in the air reaches between 40% and 70%, the moisture can wrap up dust, viruses, bacteria, etc. and sink to the ground, thereby inhibiting the spread. It can also remove odors in the air and make the air fresher and cleaner; conversely If the humidity is below 30%, viruses, bacteria and dust can spread twice as much as if the humidity is 60%.
