When you have hot flashes at night, your body overheats and begins to excessively sweat. Just like hot flashes, night sweats are caused by changing hormone levels during the menopause transition. Because of decreased estrogen levels, your body’s internal temperature gets thrown off, making it more sensitive to changes in the body temperature and overreacts to try to cool you down. These events can disrupt sleep and lead to sleep deprivation and fatigue.
HRT can help relieve this symptom, along with lifestyle changes like avoiding known triggers such as spicy foods and hot drinks.
