One wouldn’t think anything about what to wear on your head when you go to bed unless you have lost your hair due to chemotherapy. Hair keeps the heat in and when you have no hair, you get cold. Remember the pictures of people in the olden days wearing their sleep caps. Those were the days when there was no central heating and winter nights were cold.
Fashions have changed a lot since then. Chemo hats are a great option. They keep you warm at night, especially a cozy, comfortable knit that is soft on your head and stays in place. Choose a color that makes you feel relaxed and beautiful. A cotton fabric is also best to help wick away the night sweats.
