Winter Warning: Tips for Preventing Frostbite and Hypothermia
by Cynthia M. Johnson, MA
Outdoor sports don't have to stop just because it is cold. In fact, many hikers, bikers, runners, and winter sport lovers enjoy the cold of the winter months.
Follow these steps to avoid frostbite and hypothermia before you head out for a long day in the cold.
Dress in Layers
Wear clothing in layers. The number of layers will depend on the temperature and thickness of the layers. You may wear:
It is just as important to stay dry as it is to stay warm. Adjust layers as needed and bring extra clothes to change into if they get wet or sweaty.
Cover your head, face, and neck with a hat (or hood) and a scarf or a ski mask. Mittens are warmer, but gloves let you use your fingers. Try wearing light gloves under your mittens in case you need to use your hands. Keep your feet warm and dry with extra thick socks or 2 pairs of socks (wool or synthetic).
Dehydration can lead to hypothermia. Drink plenty of water and drinks with electrolytes if you will be active for a long period of time. Avoid drinks with alcohol and caffeine.
Eat for Heat
Your body needs food to fuel your exercise and to create body heat. Do not head outside on an empty stomach. And bring along plenty of snacks, like trail mix, energy bars, fruit, and bread.
Monitor Your Energy
Fatigue can lead to hypothermia. Be aware of your energy level and plan how long you will be outdoors. Rest when needed and go home early if you start feeling tired.
Bring a Buddy
A friend can help you if you get tired and keep an eye on your face, cheeks, and ears for signs of frostbite. Do frequent checks for cold, wet, and numb areas, especially your face, feet, and hands.
Choose Your Days Wisely
Temperatures below freezing (32°F or 0°C) and slightly higher temperatures with a wind chill are risk factors for hypothermia and frostbite. Keep an eye on weather forecasts and plan your outdoor activities for warmer days without snow or rain.
