We all sweat in our sleep on hot summer nights, but many have this problem year-round, especially women in their 50"s. Even people with air conditioning still find heat gets trapped between their pillow and head. The Cool Gel Pad keeps your head cool, right where it needs it most. The pad always stays cool, and never needs refrigeration! Can be placed anywhere you sit, such as the couch, an office chair, and in the car. Also very soothing for fevers, migranes, and on sunburns. It can also serve to prevent laptops from overheating.The Cool Gel Pad"s non-toxic cooling gel does not need refrigeration because it absorbs body heat to keep you cool. Slide it under your pillow case, or use it directly. Keep out of direct sunlight and hand wash periodically.
