How a Wet Towel and a Chilled Pillowcase Can Improve Your Sleep

Even a few degrees can relax muscles, ease breathing, and reduce restlessness, making it easier to drift off. A second method targets the body itself. Placing a pillowcase in the refrigerator or freezer before bed provides a cooling sensation to the head and neck. Because blood vessels are dense near the skin, this can help lower core body temperature, signaling the nervous system that it is time to relax.

Even brief contact with the chilled fabric is often enough to overcome the initial barrier to sleep, giving the body the chance to rest before heat returns. By combining these two strategies—cooling the air and cooling the body—hot, restless nights become far more manageable, offering an energy-free path to restful sleep.
