Sleep-related disorders linked to hypertension in postmenopausal women

New research suggests sleep disorders in postmenopausal women may raise the risk of hypertension — abnormally high blood pressure.

Postmenopausal women tend to have poorer blood pressure control than men of the same age, partly due to falling oestrogen.

They also report more sleep problems, including short sleep, trouble sleeping or obstructive sleep apnoea (when breathing repeatedly stops and starts during sleep).

A study of more than 3,500 naturally postmenopausal women examined links between sleep-related disorders and the odds of hypertension.

The study found that trouble sleeping and obstructive sleep apnoea were associated with higher odds of hypertension.

It also suggested a U-shaped pattern for sleep duration — both too little and too much sleep were linked with increased risk.

A subgroup analysis indicated body mass index played a role, with stronger effects seen in women with obesity.

The findings highlight the value of sleep health and weight management in reducing hypertension risk in this group.

Dr Monica Christmas, associate medical director for The Menopause Society, said: “Although it isn’t possible to determine causality or which came first—sleep dysfunction or hypertension—the study findings raise awareness around the importance of improving sleep quality and optimal weight management during and after the menopause transition as key factors in mitigating long-term cardiovascular risk.”

Sleep is fundamental to cardiovascular health, and women after the menopause commonly report difficulty getting adequate rest.

Despite a research gap focused specifically on postmenopausal women, evidence increasingly supports sleep disturbance as a substantial, often undervalued, risk factor.
