Why ice-cream sometimes causes a headache?

Blame it on physics and psychology in equal measure. When ice-cream comes in contact with the roof of your mouth, blood vessels in the mouth contract in response to the fall in temperature. This is as physics would have it. The accompanying rise in blood pressure causes the vessel walls to stretch, which in turn stimulates pain receptors in the carnival nerves.

The physiological result is that you feel aching pain in the head a few seconds after your first mouthful. However, the pain is temporary and doesn’t occur every time. Ice-cream headaches affect up to 30 per cent of people, and over 90 percent of people who also suffer from migraine. It is easily preventable. Stir the ice-cream into slush first, and try taking smaller mouthfuls. Don’t hurry and be happy.
