Anderson One of the greatest dangers to outdoor enthusiasts is hypothermia. This is a condition in which the body has lost more heat than it could produce. The result is a drop in the body's core temperature which could lead to death.
Some people believe that hypothermia can only happen in extreme cold.
This is not true. You lose heat 240 times faster when you are wet than when you are dry. By wearing a warm hat you can drastically cut heat loss. Wool caps are best, they will keep you warm even when wet. Dress in layers - match the amount of insulation you wear to your activity level and prevent overheating and perspiration.
