Quick Answer
To avoid hypothermia in cold weather, wear layers of breathable clothing, stay dry, and maintain a body temperature of at least 95°F (35°C). Monitor your body's warning signs, such as shivering, confusion, and dizziness, and take action immediately if they occur. Stay active to generate heat, but avoid exhaustion.
Layering for Warmth
When dressing for cold weather, wear at least three layers of clothing, including a base layer of thermal fabric, a mid-layer of insulating material, and a waterproof outer layer. This layering system helps to trap warm air and maintain body heat. For example, a polyester or merino wool base layer can help keep you dry and regulate body temperature, while a fleece mid-layer provides insulation without weighing you down.
Staying Dry and Active
Stay dry by wearing waterproof clothing and avoiding activities that expose you to rain or snow. If you do get wet, change into dry clothes as soon as possible. To stay active and generate heat, engage in regular physical activity, such as walking or hiking, for at least 30 minutes every hour. Aim for a moderate intensity workout to keep your body temperature elevated without overexerting yourself.
Monitoring Body Temperature
Monitor your body temperature regularly, especially in extreme cold weather. If your body temperature drops below 95°F (35°C), you risk developing hypothermia. Take action immediately if you experience any of the following warning signs: shivering, confusion, dizziness, slurred speech, or loss of coordination. Remove any wet clothing, consume warm beverages, and engage in physical activity to generate heat and raise your body temperature back to a safe level.
