We have already talked of how winter affects health in connection with fatigue. This time let us pay attention to immunity and frequent colds. Even if you do not get cold and get vaccinated against the flu in time, the number of perfectly healthy people decreases during the cold season. But is it true that immunity decreases in winter?
How winter affects health: immunity
In fact, immunity is a complex, but also a very stable system. Therefore, expressions like “his immunity fell” or “she has low immunity” usually do not correspond to reality at all.
Talking about immunodeficiency is correct only when you mean serious disorders, for example, HIV infection or leukemia. Common colds in winter have nothing to do with a decrease in the resources of the immune system.

However, the protective functions of the body can really weaken. For example, it happens when the balance of oxidants and antioxidants in the body is disrupted. That may happen in winter because of lack of fresh air, sunlight, sleep and physical activity, as well as due to malnutrition and stress.
In addition, it takes less time to catch viruses when you spend more time indoors, all windows closed.
How winter affects health: chronic diseases
Also, when you stay longer in enclosed spaces, move less and eat worse, it may literally provoke your chronic diseases. Such as inflammatory diseases or arthritis, for example.
