Sleep Disorders: Sleep and Menopause
Menopause is a stage in a woman's life when she stops having her monthly menstrual cycle (her period). It is a normal part of aging and marks the end of a woman's reproductive years. Menopause typically occurs in a woman's late 40's to early 50's.
When a woman goes through menopause, her body stops producing the hormones estrogen and progesterone. The loss of these hormones brings about various symptoms, including hot flashes (a sudden feeling of warmth that spreads over the body) and sweating (which is related to hot flashes).
Approximately 75% of menopausal women experience hot flashes, which can last for five years. Hot flashes and sweating can make it difficult to sleep. According to the National Sleep Foundation, approximately 40% of menopausal women have sleep problems caused by hot flashes. Sleeping difficulties can lead to other problems, such as daytime drowsiness.
How Can I Treat Sleep Problems Related to Menopause?
The traditional treatment for the symptoms related to menopause has been hormone therapy (HT). HT consists of estrogen given as a pill, patch, or vaginal cream, either alone or combined with progestin (a synthetic form of progesterone, or micronized progesterone). However, results from a large study, the Womens Health Initiative, showed that estrogen-progestin combination therapy caused an increased risk of breast cancer. Estrogen alone did not increase breast cancer, but the study also found that therapy with estrogen alone increases the risk of stroke in older women.
The latest recommendation for use of HT for menopause symptoms such as hot flashes is to use the lowest possible dose, with regular follow-up with your doctor.
If you decide not to use HT, the following tips might keep you cooler at night and help you sleep better.

What Alternative Treatments Are Available to Treat Hot Flashes?
Alternative treatments for treating hot flashes have included soy products such as tofu and soybeans. Soy products contain a plant hormone called phytoestrogen that acts as a weak estrogen. Studies in general do not show significant hot flash reduction with soy products; however, soy foods may lower cholesterol. High doses of soy supplements have been reported to stimulate problems with uterine lining.
Black cohosh, a perennial plant that is a member of the buttercup family, has also been used to treat hot flashes. In several studies, menopausal women who took black cohosh experienced relief from hot flashes and sweating, although most of these studies have been short-term, and used varying amounts of black cohosh from different sources. More studies are underway to determine if black cohosh reduces the frequency of hot flashes and other menopausal symptoms.
Keep in mind that alternative treatment products are not regulated or controlled by the Food and Drug Administration, and the long-term benefits and risks of these therapies are unknown. Talk to your doctor before you take any of these products.
