What happens to our body if it gets too cold?

Answer 1

In cold weather, many find that their hands and cheeks especially become dry and red. During winter months, skin may become more sensitive to shaving due to the drying effect of the cold. Other effects of cold weather damage can be dry or chapped lips, wind burnt cheeks, and red or dry patches on the arms and hands, especially the tops of the hands which are often more exposed to the cold.

Answer 2

It is called frostbite and is a form of gangrene since it is not possible for the body to repair frozen skin and tissue cells. The areas blacken and die because the water in the cells freezes,expands and breaks the cell walls causing irreparable damage.

Answer 3

The Neurons detect low body temperature and activate the Erector pili muscles to stand hair up. This gives the body heat, thats the only thing the integumentary system (skin) does. The muscular system well shiver.

Answer 4

The autonomic nervous system activates tiny muscles in the skin which causes the hairs to stand on end instead of lying flat on the skin as they usually do.

In other mammals this fluffs out the fur, increasing its ability to insulate against the cold (helping to keep warm) and making the animal look bigger (sometimes scaring away the other animal causing the original fear). But in humans all it does is cause bumps in the skin around the bases of the hairs, these bumps are commonly called "goose bumps".

Answer 5

Cold causes vasoconstriction. After prolonged exposure, reflex vasodilation occurs to restore adequate blood supply to the tissues

Answer 6

It rises. Goose bumps also form because your skin is tightening up to store heat.
