In your ears there are these things called 'Eustachian Tubes' and their job is usually to keep the pressure in your ear equal to the air pressure outside. Sucking on a candy, yawning or chewing gum is a way of helping the eustachian tubes open and equalize the pressure in your ears when the air pressure around you changes suddenly.

I used to think that you were supposed to stick them in your ears.

Here's a link that explains it very clearly. It is about pressure equalisation through the Eustachian Tubes. Apparently the swallowing is what does it (as opposed to sucking or chewing).
