Body odor changes with the seasons – How are cold winters and hot summers different?
Seasonal body odor is a common phenomenon, when changes in weather directly affect the activity of sweat glands. In hot and humid summers, the body sweats a lot, leading to an unpleasant odor that is difficult to control. Meanwhile, cold and dry winters reduce sweating, but the odor can still accumulate if you wear a lot of thick clothes and don't change or wash them often.
