In school days u may have learned that

Heat expands and cold contracts.

It is same with ur nipples, they become hard,and the other parts of your body also contracts.

Blood rushes to the nipples to keep them warm. Heat expands and cold contracts, the same thing appplies to your nipples and thats why goosebumps appear too. Some people say its because we are sexually aroused...they get hard when your even scared!
