In a new study, researchers found getting too little sleep was linked to a higher risk of having a low bone mineral density (BMD) and developing osteoporosis in postmenopausal women.
The research was conducted by a team from the University at Buffalo and elsewhere.
In the study of 11,084 postmenopausal women, the team found that those who reported sleeping 5 hours or less per night had lower BMD at all four sites assessed—whole body, total hip, neck, and spine—compared with women who reported sleeping 7 hours per night.
In addition, women reporting 5 hours or less per night had 22% and 63% higher risks of experiencing low bone mass and osteoporosis of the hip, respectively.
Similar results were seen with the spine.
The study findings suggest that sleep may negatively impact bone health, adding to the list of the negative health impacts of poor sleep.
The researchers hope that it can also serve as a reminder to strive for the recommended 7 or more hours of sleep per night for our physical and mental health.
The lead author of the study is Heather Ochs-Balcom, Ph.D. of the University at Buffalo.
The study is published in the Journal of Bone and Mineral Research.
