Sleep and Bone Density

Osteoporosis

Sleep Duration and Bone Density

Several studies have explored the relationships between sleep duration and bone mineral density (BMD).
One such study found women over 45 years of age with a short sleeping duration were more likely to have lower total and all body regional BMD after adjusting for potential covariates. Compared to those who slept 8 hours, individuals who slept 6 hours or less had significant lower total and regional BMD.
Improving sleep quality and targeting 8 hours sleep per night, combined with management of other risk factors may be preventive to osteoporosis.
