The best way to treat night sweats is to eliminate the cause. It may be necessary to go through the list of possible causes and eliminate them one by one. If no cause seems to be forthcoming, then you may suffer from Primary Hyperhydrosis. This disorder can become severe enough to interfere with day-to-day life, and consists not only of night sweats, but of excessive sweating throughout the day. If severe enough, your doctor may suggest surgery for the removal of the sweat glands. Possibly beneficial lifestyle changes include avoidance of alcohol and spicy foods. Talk to your doctor about any medications that you are taking to see if they could be the cause. Sleep in a cool room and, if weather permits, leave the window open, or try using a fan. Get up and take a shower or a sponge bath; change your bedding and put on fresh nightwear; have a cold drink such as water or fruit juice. A cold shower before bed might prevent an attack of night sweats.
