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.

Why do you never sneeze just one time?
Some people only sneeze once. Like me but my sneeze is a scream. I sneeze from my throat so that is probably why I only sneeze once. When you sneeze it is normally because your nasal passages are filled with mucus and your body is trying to remove it. When you sneeze multiple times it is just a reaction. Have you noticed if someone tickles your nose or you look at the sun you sneeze? After one sneeze some people have that tickle feeling so they sneeze repeatedly.
