Hyperhidrosis and Sleep
Generally speaking focal hyperhidrosis which is hand sweating and or foot sweating does not happen while the subject is asleep. Many will ask why? The answer for that question is that the sympathetic activity goes down while we are asleep. Those patients who suffer from hyperhidrosis will tell you that focal hyperhidrosis in the hands and feet starts after they wake up. Again the physiological explanation for that is that during sleep the overall activity of your body is down. This is a very simplistic way to explain it but we do not have a very good answer as to why it happens in this rhythm. Also a lot of patients who suffer from hyperhidrosis will tell you that drinking excessive amounts of alcohol or using recreational drugs will render their hyperhidrosis to a lower level. Again here the reason for this lies in the fact that by using those substances it reduces the overall activity of the body. We do recommend this as treatment due to obvious reasons.
