Topic:   Hypothermia QC-0503
 
Basics:
Resource: Critical Temperatures for Hypothermia
Critical Temps
 

Hypothermia or low body core temperature typically results from exposure to the elements. It is expecially dangerous for immersion in cold water since heat loss occurs rapidly. Recognizing symptoms is critical as even a mild case could impact your paddling ability and affect your group. In cold water you may have only minutes to perform a rescue.

 
Question:  

When are paddlers most likely to encounter hypothermia?

 
Answer:  

Hypothermia can occur year round but proceeds faster in cold water. Winter and spring water temperatures are cold in our area, and prevail year round in northern locations. It is a special risk on warm early spring days when paddlers tend to dress for the air temperature but the water is still very cold. Prolonged exposure to even mild conditions for children and certain adults are special risk conditions.

 
Question:  

What kinds of clothing are good for cold water?

 
Answer:  

Outdoorsmen say "cotton kills" because it holds moisture next to the skin drawing heat out of the body. Wool or synthetic fibers which "wick" are better choices. Commercial paddling gear such as paddle jackets, wet suits or dry suits offer great protection from spray, rain or immersion.

 
Advanced Concepts:   You may want to get more information on the following:
  • How does one choose a wetsuit or a drysuit?
  • What are the pro's and con's of poggies?
  • At what water temperatures does protection become critical?
  • What special group considerations apply for cold water conditions?
