Creases Or Folds In The Skin:
The areas of the body having creases in the skin such as the neck, groin, armpit, and elbow joint makes it difficult for the skin pores to allow the perspiration, and thus, the sweat starts accumulating in the sweat ducts. The folds on the skin which touch adjacently each other also make it very difficult for the sweat to evaporate from the surface of the skin and cool down the body’s temperature.
Heavy clothing:
Overdressing and bundling up on cloth layering in the wintertime also results in the trapping of sweat in the sweat gland ducts and also leads to skin rashes.
