Q: I sweat a lot when I sleep, and it’s been going on for years. Now that I’m getting older, the problem is getting worse. Is there anything anyone can do about this?A: This may be a symptom of your thyroid gland not working properly. Talk with your doctor about testing to see if you have low thyroid function or an underactive thyroid gland. You can take medication to regulate the hormone to help control sweating while you sleep. Also try using a cooling product such as Vicks VapoRub around bedtime because it will cause drowsiness as well as stop perspiration at night by reducing body temperature.
