Those at greatest risk are the ill prepared. It is likely to happen on cold, wet, windy days to people who are poorly clothed, hungry and tired. This phenomenon is known as windchill. Hypothermia is a dangerous condition and is often accompanied by mental confusion where the person affected does not realise what is happening preventing them from seeking help.
Extreme hypothermia can lead to death in just a few hours.
There is an abundance of excellent protective clothing available for outdoor enthusiasts. Specialist advice should be sought as to the best equipment for a trip, including survival equipment. Loss of articles of clothing in an accident can be disastrous unless spares are carried. This involves seeking shelter, insulating and protecting them from the cold environment. Replace any wet clothing with dry ones.
