Most body heat is lost through the head area so it really helps to wear a hat.
A soft stretch hat is nice to sleep in. Wear warm socks on your feet as well to help keep your whole body warm. A microwaveable heating pad is also an excellent way to keep yourself warm and toasty. Clean Up the Air Many PWCs have an increase in allergies and other sensitivities. Consider purchasing an air cleaner that has a HEPA filter with a charcoal pre-filter.
