On hot summer days, when not a hint of wind blows, sweat adheres to the skin and forms an annoying film of humid air that makes it difficult for the sweat glands to work. The fan, as well as the fan, come to our aid.
By fanning ourselves, we create an air current that removes and removes the moistened air that surrounds the epidermis . This facilitates the evaporation of sweat and, therefore, makes us feel a pleasant cooling effect.
