Hypothermia and Frostbite

Hypothermia

Hypothermia is a life-threatening condition. People with hypothermia can no longer keep themselves warm and cannot re-warm themselves without assistance.

In Auyuittuq, hypothermia is a risk year-round. It can be particularly dangerous in summer when people least expect it. Summer air temperatures can change rapidly from warm (15º C) to cool (0º C or below). Rain or snow can quickly blow in off the ocean. Prolonged exposure to cool, wet, and windy conditions can lead to hypothermia for those who are unprepared. Exposure to glacial meltwater during river and stream crossings can also lead to hypothermia. Know the signs and symptoms of hypothermia, know how to treat it and take precautions to prevent its onset. If your clothes become wet in the cold, immediately change to dry clothing.
