Could getting enough sleep help prevent osteoporosis?

In people's early- to mid-20s, they reach what is called peak bone mineral density, which is higher for men than it is for women, according to researchers. This peak is one of the main determinants of fracture risk later in life. After reaching this peak, a person's bone density remains roughly stable for a couple of decades. Then, when women enter the menopausal transition, they experience accelerated bone loss. Men also experience bone density decline as they age.

"Therefore, it's important to look for novel risk factors and consider what else changes across the lifespan like bone does -- sleep is one of those," she added.In people's early- to mid-20s, they reach what is called peak bone mineral density, which is higher for men than it is for women, Swanson said. This peak is one of the main determinants of fracture risk later in life.

"And it's not just sleep duration and composition that change. Circadian phase preference also changes across the lifespan in both men and women," Swanson said, referring to people's preference for when they go to sleep and when they wake up.Genes that control our internal clock are present in all of our bone cells, Swanson said.

"This rhythmicity is likely important for normal bone metabolism and suggests that sleep and circadian disturbance could directly affect bone health," she said.To further understand this relationship, Swanson and colleagues researched how markers of bone turnover responded to cumulative sleep restriction and circadian disruption.

The research team measured bone turnover markers at the beginning and end of this intervention and found significant detrimental changes in bone turnover in both men and women in response to the sleep and circadian disruption. The detrimental changes included declines in markers of bone formation that were significantly greater in younger individuals in both sexes compared to the older individuals.
