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 significantly lower total and regional BMD.
Improving sleep quality and targeting 8 hours of sleep per night, combined with management of other risk factors may be preventive to osteoporosis.
