Warm broth and food is better. Symptoms include a loss of feeling in the extremity and a white or pale appearance. This research was to simulate a person near a body of water or a mariner. Frostbite Threshold: For the first time, the wind chill temperatures include specific threshold values that provide specific warning of time-to-frostbite at given levels of wind chill. Incorporates modern heat transfer theory, based on heat loss from the body to its surroundings during cold and breezy/windy days. A. At this wind chill temperature, exposed skin can freeze in 30 minutes. The wind chill temperature is how cold people and animals feel when outside. This formula is: Wind chill = 35.74 + 0.6215T -35.75(V^0.16) + 0.4275T(V^0.16) Where T = temperature. Winter weather presents hazards including slippery roads/surfaces, strong winds and environmental cold. Wind Chill Calculator. Hypothermia occurs when body temperature falls below 95˚F.
