Stay Safe in Extreme Cold
Protect yourself in extreme cold by layering moisture-wicking fabrics, keeping your skin covered, and monitoring your body for signs of frostbite or hypothermia. Always carry a portable power bank, as cold temperatures drain smartphone batteries in minutes.
- Master the three-layer system. Wear a synthetic or wool base layer (never cotton) to wick sweat, a fleece or down mid-layer for insulation, and a windproof/waterproof outer shell to trap heat.
- Protect your extremities. Wear thermal socks under wool socks, a hat that covers your ears, and windproof mittens rather than gloves to keep fingers together for better heat retention.
- Watch for the 'umbles'. If you or your companions start stumbling, mumbling, or fumbling, it is a primary sign of hypothermia. Get indoors immediately and get warm.
- Manage your tech. Keep your phone and camera batteries inside your inner jacket pocket against your body heat; cold weather will cause them to die instantly if left in an outside pocket.
- How do I know if I have frostbite?
- Check your skin for white, waxy, or greyish-yellow patches, or if the skin feels unusually firm or numb. If this happens, do not rub the area; get to a warm environment and soak in lukewarm water.
- Does drinking alcohol help keep me warm?
- No. Alcohol dilates your blood vessels, which makes your body lose heat faster, even though it may make you feel temporarily warmer. Avoid it until you are safely indoors.
