Does exercise influence the body’s internal clock? Few of us may be conscious of it, but our bodies, and in turn our health, are ruled by rhythms. “The heart, the liver, the brain — all are controlled by an endogenous circadian rhythm,” says Christopher Colwell, a professor of psychiatry at the University of California, Los Angeles’s Brain Research Institute, who led a series of new experiments on how exercise affects the body’s internal clock. The studies were conducted in mice, but the findings suggest that exercise does affect our circadian rhythms, and the effect may be most beneficial if the exercise is undertaken midday.
My goal for 2013 is to have a more regulated exercise schedule — preferably five days a week in the morning. Morning work outs help wake me up and I don’t have to worry all day about getting exercising in after work. After reading this article, I’m thinking maybe I should make it a once-a-week goal to go on a short work during my lunch break. Then I think to myself, “Lunch break? Ha!” I usually take lunch at my desk.
When is your favorite time to work out? Is this a routine, or is your schedule more sporadic? Would your workplace allow you to take an hour break to exercise? I would love to know!
