"Is it true that the month you were born predicts your future health? If so, what can I do to change this if I was born in a bad health month?" —Cercy M., San Francisco
Shockingly, there does seem to be science to back this up. In a study published by the International Journal of Sports Medicine, children born in the fall, particularly October and November, tended to be in better shape, and healthier overall, than those born in the spring, between April and June.
Why? To find out, Gavin Sandercock, Ph.D., clinical physiologist at the School of Biological Sciences at Essex University, studied more than 8,000 boys and girls for four years to examine the phenomenon, and he has a few theories. For instance, it may be “because their mothers get lots of vitamin D in the last trimester, which helps their muscles develop,” he says.
Not that you’re necessarily doomed to a life of chronic illness if you were born in an “unhealthy” month.
