That means being too hot or too cold can prevent you from getting a good night’s rest. Silk is ideal, according to Sleep.org, because it keeps you warm when you’re cold and cool when you’re hot. If silk is too pricey, try breathable cotton in the warmer months and cozy flannel during the cold. These innocent habits are completely ruining your sleep quality, too.
