Why does humidity in the air creates physical discomfort to people?
When the atmosphere is humid, it means there are abnormally high moisture contents in the air. Such high moisture contents do not allow perspiration to evaporate or escape from human body, as the air is already saturated with moisture. Unescaped sweat hampers breathing and the body does not cool down. Resultantly, one feels suffocated and uncomfortable in humid atmosphere.
