Too much exertion can cause a heart attack. When shoveling snow or doing other activities in the cold you should always set a slow pace. Take frequent breaks and warm yourself regularly. The signs of hypothermia include uncontrollable shivering, disorientation, slurred speech, and drowsiness or exhaustion. If the body temperature has dropped below 95F seek immediate medical help.
Frostbite can also occur from exposure to the cold.
Frostbite causes a loss of feeling and usually occurs in extremities such as toes or fingers first. A person suffering from hypothermia must have their chest, neck and head warmed first. Remove layers of clothing to avoid perspiration, and subsequent chill. All rights reserved.
