This is a question that has been asked since ancient times. It’s an important question because there are many more ways to sweat than just the two mentioned above, and some of these other forms can be dangerous or even fatal if not properly managed.
The main difference between profuse sweating on the hands and feet, which appears in response to heat, exercise or emotional stress, and “normal” sweating occurring during sleep is that with profuse sweating you will also see it elsewhere on your body, i.e., on your face, underarms etc. This condition is called hyperhidrosis (pronounced HY-per-hi-duh-skye), causing excessive perspiration in various locations around the body. Hyperhidrosis occurs when there are too many nerve impulses triggered by epinephrine (adrenaline) in the bloodstream producing excessive amounts of sweat glands located all over our bodies–our faces especially! Many people who suffer from this urge for nice clothes make sure they have enough air conditioning before leaving their homes but never think about how much air conditioning they need while sleeping at night! Over time although most patients eventually get used to wearing their oversize clothes no one ever fully recovers from hyperhidrosis despite all possible treatments available today including prescription medications such as cyproheptadine hydrochloride (Periactin). The only thing I know of that really works for this condition is understanding what triggers it so you can learn to control it
