Many menopausal women suffer from insomnia, but a new study has found that if menopausal women take a 12-week yoga class and practice yoga at home more often, they can reduce their insomnia problems, but yoga is ineffective in improving hot flashes and night sweats. The study says that many women suffer from insomnia when they reach menopause, and it suggests that practicing yoga may help these women improve their insomnia. Currently, the U.S. Food and Drug Administration only allows the use of hormone therapy to treat hot flashes and night sweats, but fewer and fewer women are opting for hormone therapy, so the researchers wanted to find out if natural methods such as yoga, exercise, and the intake of fish oils could improve the discomfort of menopause. Researchers from the American Institute of Group Health studied 249 healthy women who were randomly divided into three groups: one group did yoga regularly, another group did moderate aerobic exercise consistently, and one group was divided into two groups, with some taking Omega-3 fatty acid supplements and others using a placebo. The results of the study showed that exercise could slightly improve sleep quality and had a slight effect on improving insomnia and depression symptoms, while yoga improved sleep quality and those who did yoga were also less likely to experience depression symptoms.
