Why do your nipples harden when you sneeze?

Answer 1

Nipples get hard in the cold in order to preserve heat. If a nipple is exposed to the cold the automatically contracts, and this in turn causes the nipple to become smaller, wrinkled and hard. The reason this happens is to reduce the amount of surface area on the nipple that is exposed to the cold. As a result of this the body losses less heat and the amount of energy required sustain homeostasis (keeping normal body temperature) is decreased. Decreasing surface area of the skin is the ultimate reason why nipples get hard when it is cold.
