Cleaning and disinfecting habits have become common around the world after Corona, but medical experts are warning that excessive cleaning can be harmful to the human immune system. According to new scientific research, a completely germ-free environment can weaken the body’s natural immune system. According to the scientific theory of the hygiene hypothesis, it is necessary to have adequate exposure to germs and environmental pollutants during childhood, this process enables the immune system to learn and fight diseases. Children who are exposed to fewer natural germs in early life are at higher risk of allergies, asthma and autoimmune diseases. Hand sanitizers, antibacterial sprays and unnecessary cleaning also eliminate the body’s beneficial bacteria, which are essential for gut health and the immune system.
