Rising temperatures and dry air: a threat to the respiratory system
The increase in temperature on Earth is negatively affecting not only climate change but also human health. According to scientists' research, a decrease in air humidity can seriously harm the respiratory system. Breathing dry air for an extended period increases the risk of asthma, chronic cough, and allergic rhinitis.
Effects of dry air on the respiratory system
Scientists studied the bronchial epithelial cells that line the respiratory tract under laboratory conditions. They found that in dry air conditions, the cells produce less sticky mucus and that pro-inflammatory cytokines are activated. This leads to inflammation of the respiratory tract.
Experiments on mice and results
Researchers also conducted experiments on mice. They exposed healthy mice and those prone to respiratory diseases 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 risks
Climate forecasts indicate that by 2030, air humidity on Earth will decrease further. This could exacerbate the drying of the respiratory tract and the spread of related diseases. Especially, people who frequently use air conditioning are at a higher risk of facing this problem.
What recommendations do scientists provide?
The authors of the research emphasize the need to pay special attention not only to the cleanliness of the air but also to its humidity. According to them, maintaining humidity levels in a normal state can play a crucial role in preventing respiratory problems.
Therefore, experts recommend regularly humidifying home and office spaces, spending more time in natural environments, and drinking enough water. This will not only protect the respiratory tract but also help strengthen overall health.
