The rise in global temperatures is not only having a negative impact on climate change, but also on human health. According to scientists, a decrease in air humidity can cause serious damage to the respiratory tract. Prolonged exposure to dry air increases the risk of asthma, chronic cough, and allergic rhinitis.
Dry air and the effects on the respiratory tract
Scientists studied bronchial epithelial cells that line the respiratory tract in laboratory conditions. They found that in drier air, the cells produced less sticky mucus and activated cytokines that cause inflammation. This leads to inflammation of the respiratory tract.
Experiment and results in mice
The researchers also conducted an experiment on mice. They exposed healthy and respiratory disease-prone mice to dry air for a week. As a result, immune cells that protect their lungs accumulated and an inflammatory process occurred. This shows that dry air is dangerous not only for humans, but also for animals.
Climate change and future threats
Climate forecasts indicate that by 2030, air humidity on Earth will decrease further. This can lead to drying out of the respiratory tract and an increase in the spread of related diseases. People who use air conditioners a lot are especially likely to face this problem.
What recommendations do scientists give?
The authors of the study emphasize that special attention should be paid not only to the cleanliness of the air, but also to its humidity. According to them, maintaining normal humidity levels can play an important role in preventing respiratory problems.
Therefore, experts recommend regularly humidifying your home and office, spending more time in nature, and drinking enough water. This will not only help protect your respiratory tract, but also improve your overall health.
