Avoid contact with cold surfaces. Body heat will transfer to the cold surface. This cold surface can include wet clothing. Protect the body with wind-proof clothing. Wear a hat to prevent rapid heat loss from the head.
Wind removes the warm air which insulates the body.
Avoid overheating by overdressing or overexerting. Any moisture next to the skin will cause body heat loss because the body's heat will be used to evaporate the moisture. Babies and young children can be easily overheated by being dressed too warmly for the situation, such as being bundled up while shopping, and then will cool quickly when taken out into the cold air. Layer clothing so that clothing can be adjusted to the temperature as needed. Layers of clothing can also help in keeping the person dry.
