Hi dear, Understanding your concern. The body normally produces sweat as a way to help keep cool. Sweating normally occurs with exertion such as when exercising or in high temperatures. However, there are other reasons for sweating. Sweating can be triggered by fear or anxiety, and this is often referred to as a cold sweat. It comes on suddenly and results in cool, damp skin. It is the body s reaction to stress as part of the fight or flight response that helps us to react in a dangerous situation. A nightmare during sleep can trigger a cold sweat, and people with prolonged stress or anxiety problems can experience sweating as a symptom. Alcohol, some drugs, spicy foods. Consumption of any of these can cause night sweats. And by drugs, I’m not necessarily referring to street drugs. Some prescription drugs, like Zoloft, can also cause night . Sleep apnea and diabetes are the one that most concerns . Various anticholinergic medications have success in treating excessive sweating. A treatment with Robinul starts at 1 or 2 mg one to three times a day and has good effects on excessive manifestations of sweating. Another medication used in the treatment of excessive sweating is Propranolol. It mostly targets stress induced hyperhidorsis and is successful in eliminating most of the negative effects of the condition. Botulinum toxin type A (BTX-A) is sometimes used to treat night sweating. It is injected into the skin and it acts as a temporary blockage for the sympathetic nerves that stimulate the excessive sweat production. Just because you wake up with wet sheets does not mean you have a problem, it could be as simple as a dream, stress at work or similar factors. If however, you wake up at night with bedding and nightclothes damp with sweat at least 4 of 7 days, then you should seek these medical attention. Hoping your concern has been resolved. Please do get back for any further queries. Regards, Dr. Harry Maheshwari
