Poor sleep and circadian health are linked to increased risk for cardiovascular disease, metabolic dysfunction, and cognitive performance decrements in midlife women.

The paper reports that midlife women, especially during the menopausal transition, experience sleep and circadian disturbances driven by hormonal changes, vasomotor symptoms, and aging. These disturbances are associated with elevated risks for cardiovascular disease, metabolic dysfunction, and cognitive decline.
