Facts About Extremely Cold Weather

Facts About Extremely Cold Weather
Cold weather sports are immensely popular and people travel long distances to enjoy these activities. But many people lack sufficient education about the elements. This leads to many unnecessary ruined trips, injuries and even deaths. Preventing problems from cold weather is a lot easier than fixing them.

Bodily Reactions

The human body responds to cold weather in three basic ways. Initially, the body produces heat through shivering. Then by shunting blood from the skin and toward major organs, the body reduces heat loss, which explains why hands turn blue in cold weather. Finally, the body releases stored sugar, providing fuel.

Heat Loss

The body loses heat in four ways. Conduction is heat directly transferred between objects in contact. Convection is heat removed by a stream of cold air or water. Evaporation is heat absorbed by evaporating sweat. Radiation is heat emitted and absorbed by cold objects around you.


The most recognized injuries are frostbite and hypothermia. But several others exist, most linked to blood circulation problems. Raynaud's phenomenon results from chronic constriction of the hands' blood vessels. Child blains and trench foot are similar conditions.


Keep all skin covered and dress in loose layers of clothing, especially hand and footwear. Snack and drink regularly but avoid caffeine and alcohol. Most important, stay dry.


Alcohol and cold weather don't mix. Alcohol increases blood flow to the skin, inhibits shivering and increases fluid loss. Reducing pain and cold sensation along with causing poor judgment and coordination, alcohol reduces the response to early warning signals, which indicate developing problems.
