![]() ![]() If no help is available, the victim should be warmed slowly with warm liquids along with dry clothing and blankets. Immediate medical attention should be given to victims suspected of suffering from hypothermia. Warning signs of hypothermia include uncontrollable shivering, memory loss, disorientation, slurred speech, and drowsiness. If you or your clothing are wet, then hypothermia becomes even more likely. ![]() Most people are surprised to learn that hypothermia deaths can occur with temperatures between 30 and 50 degrees. When you hear of a hiker, climber, hunter, or a stranded traveler perishing from cold weather exposure, hypothermia was the cause. Hypothermia is a dangerously low body temperature and is the most common winter weather killer. If you suspect you are experiencing frostbite, hold the frostbitten area closely against warm skin to return blood flow and warmth to the affected area. When frostbite starts, feeling is lost in the affected area and the frozen tissue will take on a white or pale appearance. To minimize frostbite, make sure all body parts are well covered. It first affects exposed body tissue where blood circulation may be limited such as your fingers, toes, nose and ears. Military Equipment Design Practices, Vols. Wind chill values near minus 25 degrees mean that frostbite is possible within 15 minutes.įrostbite is the freezing of skin and the body tissue just beneath it. Chart ( Numbers on Curves Represent Windchill in kg - cal / mhr ) ( Ref. This means that your body will lose heat at the same rate as it would if the air temperature were minus 30 degrees with no wind. For example, a temperature of minus 5 degrees occurring with a 20 mph wind gives a wind chill near minus 30 degrees (see wind chill calculation table below). The calculation utilizes wind speed in miles per hour and temperature in degrees Fahrenheit. ![]()
