Air humidity is a measure of the amount of water vapor present in the air. The ideal air humidity should be between 30% and 50%. Human health is affected by moisture in the air. The humidity should not be too high because it creates favorable conditions for many pathogenic microorganisms to grow and should not be too low because it causes dryness of the skin and irritation of the respiratory mucosa.1. What is air humidity?
Air humidity is a concept that refers to the level of water vapor present in the air. Some other in-depth concepts related to air humidity include:
Absolute air humidity is the amount of water vapor present in a unit volume of air. Relative air humidity is a quantity commonly used in daily life, indicating the percentage of water vapor in the air. When the relative humidity reaches 100%, the air is saturated in terms of water vapor content. Proportional humidity indicates how much humidity varies with different temperatures. Measurements related to air humidity have many important roles in many different areas of life such as agricultural, forestry and fishery production, health, mobility, ...
Earth's surface Covered by more than 70% of water comes from oceans, rivers, lakes and ponds. Under the action of wind and sunlight, this amount of water can evaporate and fly into the air. The higher the temperature, the faster and more chaotic the water molecules move, causing more water vapor to be released into the air. This is the main mechanism of moisture formation in the air. Air humidity is influenced by ambient temperature, pressure and wind. When the air temperature rises high in the summer months, the air humidity will drop to low.
In contrast, in the winter months, the air humidity is high and saturation can be reached. Thus, temperature and humidity are two quantities that have a close relationship with each other. People apply this by adjusting the temperature if they want to change and controlling the humidity at the right level.

2. What is the ideal air humidity?
For humans, the ideal air humidity should range from 40% to 70%, especially for babies it should be from 40% to 60%. At this level of air humidity, harmful microorganisms are usually kept under control, without overgrowth.
In large buildings or in hospitals, the air humidity is set and maintained at an average of about 55%. When the air humidity is too low or too high, it can be harmful to human health.
3. Effects of too high air humidity on human health
Air humidity is said to be high when it exceeds the 70% value threshold. The humidity in the air increases too high to the point of saturation, which is the cause of many disease problems, adversely affecting human health, especially children and people with weakened immune systems. Disadvantages caused by too high air humidity: Causes mold, destroys clothes and household items Difficulty in maintaining medical equipment Accumulation of fluid on walls and floors, the surface becomes slippery, easy to fall Bacteria, mold and other microorganisms have the conditions to grow. They are the allergens of respiratory diseases such as pneumonia, bronchitis, bronchial asthma, chronic obstructive pulmonary disease and some other skin diseases.
