What is the impact of air humidity on people

When it comes to air humidity, many people may not know what it is. Air humidity is something that people cannot see or touch, but it does exist, and it does have a great impact on people. Air humidity has a normal range. When the air humidity is higher or lower than the normal range, it will have a certain impact on people's health.

Too much or too little air humidity is harmful to human health. When the humidity is too high, the pineal gland in the human body secretes a large amount of pineal hormone, which makes the concentration of thyroid hormone and adrenaline in the body relatively lower. The cells will become "lazy" and people will feel listless and sluggish. Working or living in humid places (such as mountains and islands) for a long time can also make you more susceptible to rheumatic arthritis, rheumatoid arthritis and other rheumatic diseases. However, when the humidity is too low, evaporation speeds up and the dry air can easily take away moisture from the human body, causing dry and cracked skin, irritation of the oral and nasal mucosa, and symptoms such as thirst, dry cough, hoarseness, and sore throat. It can easily induce pharyngitis, tracheitis, pneumonia and other diseases. Modern medicine has also confirmed that air that is too dry or too humid is conducive to the reproduction and spread of some bacteria and germs.

Scientists have determined that when the air humidity is higher than 65% or lower than 38%, germs multiply fastest; when the relative humidity is between 45% and 55%, the mortality rate of germs is higher. It is precisely because air humidity affects human health that people in their daily lives should not only pay attention to temperature and whether it is sunny or rainy, but also pay attention to the air humidity and its changes around them at all times.

The above is the relevant content about the impact of air humidity on people. If the air humidity is too high or too low, it will pose a threat to human health, so people still need to pay attention to air humidity in their daily lives. Especially in winter, if you want to go out, it is recommended that you wear a mask to avoid inhaling some bacteria or germs.
