Sleep Deprivation Could Be Bad For Bones

Who knew sleep could be so important to bone health?

Besides having effects on our productivity , immune system and anxiety levels , a new study in rats shows that sleep deprivation could also impact the health of bone and bone marrow.

The findings, published in the journal Experimental Biology and Medicine , showed that sleep-deprived rats had decreased bone mineral density -- which researchers said in the study indicated osteoporosis. The rats also had less fat in their bone marrow than fully-rested rats, as well as double the amount of megakaryocytes, which are bone marrow cells that produce platelets.

"Taken together, these findings suggest that chronically inadequate sleep affects bone metabolism and bone marrow composition in ways that have implications for development, aging, bone healing and repair, and blood cell differentiation," the researchers wrote in the study.

"If true in humans, and I expect that it may be, this work will have great impact on our understanding of the impact of sleep deprivation on osteoporosis and inability to repair bone damage as we age," the editor-in-chief of Experimental Biology and Medicine Dr. Steven R. Goodman said in a statement.

Sleep's not the only thing that could affect bone health -- the foods you consume can also make a big difference. Click through the slideshow for some foods that can promote healthy bones :
