Winter eagle watchers must often endure harsh weather conditions. Below freezing temperatures combined with strong winds can create hazardous conditions for those not adequately prepared. Frostbite and hypothermia may occur when the human body is exposed to extreme cold for an extended period of time.
Frostbite is the localized freezing of parts of the body.
Hypothermia is a subnormal temperature of the body overall. When cold discomfort progresses to numbness action should be taken to prevent freezing. The use of gloves or mittens can protect fingers while muffs or hoods can protect ears. Toes can be protected with insulated boots and heavy socks. Boots and gloves should not be so tight to restrict blood circulation.
