Headaches - oldest excuse in the book but they can make an adult groan out loud, rock back and forth on the floor, cradle their head in pain or crawl on their knees.
If you start thinking what causes headaches, you’ll end up with a migraine yourself.
There are more than 200 types of headaches but a rare, intensive kind of pain that affects more than two million Indians (according to the National Headache Foundation) strikes at the change of seasons.
Just about everyone knows someone who has a migraine - an intense throbbing headache in one area of the head, commonly accompanied by nausea, vomiting and extreme sensitivity to light and sound - and for some people this happens each time the season changes. So spring does not always mean warmer weather, blooming flowers - it’s also a world of pain.
But what’s the science behind a fall mold headache, a summer migraine or a winter cluster headache? Or is it just in your head?
