It’s 3 a.m. … you may be fast asleep, but do you know what your bones are up to? A new study in healthy young women and men shows that while we’re counting sheep, our bones get looted of their precious calcium. All day long, we naturally lose some old bone.
But this study showed that form 11 p.m. to 7 a.m. the rate of bone loss leaps 11 percent over daytime rates (Journal of Clinical Endocrinology and Metabolism, November 1995). In fact, the fastest bone loss of all occurs at about 3 a.m.
We’ve reported before that bedtime may be the best time for a calcium-rich snack like cocoa or for a calcium supplement. After this study, it’s easy to see why. A calcium nightcap looks smarter than ever!
