Much less sleep is associated with a decrease in bone mineral density (BMD) and an increased risk of osteoporosis, researchers warn.
Osteoporosis is a disease in which the bone is weak, increasing the risk of fracture.
"Our findings suggest that sleep can have a negative impact on bone health, which is included in the list of negative health effects of bad sleep," said Heather Oaks-Balcom, lead author of the study at the University of Buffalo, USA.
In a study of 1,3 post-menopausal women, all four sites determined by those who reported to sleep five hours or less per night had lower BMD - whole body, total buttocks, neck and spine - compared to women who were required to sleep seven hours per night. Said.
After adjusting, women who report five hours or less per night have a 22 percent and 5 percent higher risk of osteoporosis of the lower bones and buttocks, respectively.
Similar results were observed along the spine.
"I hope this serves as a reminder to us to try to sleep seven or more hours per night in our physical and mental health," says Ochs-Balcom.
The research was published in the Bone and Mineral Research Journal.
