U-Shaped Sleep Duration Linked to Depression in Postmenopausal Women

Depression remains a significant clinical challenge in postmenopausal care, with global prevalence estimates suggesting that approximately 35% of women in this demographic experience depressive symptoms [1, 2]. The psychiatric burden of the menopausal transition is often multifaceted, frequently linked to a history of mental illness, the presence of chronic disease, and the physiological impact of hormonal shifts [2]. Current management strategies for mood disturbances in this population range from mind-body exercises and aerobic activity to pharmacological interventions such as melatonin or hormone replacement therapy [3, 4, 5]. However, the efficacy of these treatments can be inconsistent, and many patients continue to experience psychological distress despite standard interventions [5, 6]. Identifying specific, modifiable lifestyle factors is therefore essential for refining screening protocols and improving long-term patient outcomes. A new study now offers fresh insights into how daily sleep duration may influence the risk and severity of depression in this population.
