Is Hypothermia a Common Risk in Cold Weather Survival?

Understanding Hypothermia

Hypothermia occurs when the body’s heat loss exceeds its heat production. In cold weather, this can happen quickly, especially if you’re wet, wind-exposed, or wearing inadequate clothing. In as little as 15-30 minutes, hypothermia can set in, depending on the environmental conditions. The symptoms of hypothermia include shivering, confusion, drowsiness, and loss of coordination.

Recognizing the Stages of Hypothermia

The American Red Cross defines the stages of hypothermia as mild, moderate, and severe. Mild hypothermia occurs when the body temperature falls between 95-90 degrees Fahrenheit. At this stage, the individual may still be conscious and able to walk. Moderate hypothermia occurs when the body temperature falls between 90-80 degrees Fahrenheit, and the individual may experience confusion, slurred speech, and loss of coordination. Severe hypothermia occurs when the body temperature falls below 80 degrees Fahrenheit, and the individual may become unconscious, experience cardiac arrest, and even die.

Treatment and Prevention

Treating hypothermia requires immediate action to rewarm the body. Remove any wet clothing and replace it with dry, warm clothing. Use a space blanket or emergency bivvy sack to retain body heat. If possible, use a portable heating source, such as a hand warmer or a portable heater. In severe cases, call for medical help or seek shelter in a warm location. Prevention is key, so always dress in layers, stay dry, and seek shelter if you’re exposed to cold temperatures for an extended period.
