Most of the time, excessive sweating is not a serious medical condition. It can be annoying and uncomfortable for some people who wear suits or bathing suits in hot weather, but it’s usually only temporary and will clear up on its own. Excessive sweating is sometimes called hyperhidrosis or eccrine hyperplasia (growing more than normal sweat glands).
What causes excessive sweating?
Excessive sweating occurs when there are too many sweat-producing cells (called sebaceous glands) present in your skin. The excess sweat produced by these cells isn’t always noticeable because they’re located deep under the surface of your skin. However, if you have this condition, you may notice that your hands get wet even when there aren’t any other obvious reasons why you might feel sweaty; for example: Sitting at a desk with your palms exposed to air while typing on a keyboard
