Lab tests at the Medical College of Wisconsin show that if you continually go to bed too late, you may be draining calcium from your skeleton.

According to researcher Carol Everson, “… the potential medical implications [of our study] are far-reaching and may include poor repair of microdamage from activities of daily living, introduction of osteoporotic processes, and changes to progenitor cells that may affect disease predisposition and disease resistance.”

The study was published in Experimental Biology and Medicine. Dr. Steven R. Goodman, editor-in-chief of the journal, warns: “With increased life stress due to work-related, financial and other issues a large percentage of us are experiencing difficulties in sleeping. While we know that chronic sleep loss can affect our health little specific information has been available on how it may impact bone formation or loss.”
