According to a 2001 study published in the European Journal of Physiology, oral contraceptives can affect sleep cycles and raise the body temperature of young women–another factor that plays a role in how well an individual sleeps. A woman’s menstruation cycle can also affect her body temperature, and therefore, how well she sleeps.
