The following points can assist to avoid hypothermia:
- Stay dry : put on rain-gear before you get wet
- Strip off wet clothing and put on dry clothes
- Beware of wind - it whips heat away from skin, and cools wet clothes
- Wear a warm cap to avoid heat loss
- Have warm, sweet drinks
- Seek shelter while you still have energy, but try to stay near the path.
