You can acclimatize yourself to cold weather. "Your body will tolerate the cold much better if food and water balance are maintained." Staying hydrated is also key, Greenway said. ![]() "This is all-important, to keep your blood sugar up enough to provide the energy you need to keep warm in a cold situation." "It always helps to be well-fed in the backcountry when it's cold," he said. That means "as you get colder, shivering actually stops, so then your core body temperature just plummets."īeing well-fed - meaning consuming more calories than you're burning - will help your body handle the cold better, according to Greenway. The body stops shivering when the muscle contractions are no longer effective in producing heat, he said. People with mild hypothermia will shiver, but those with moderate hypothermia may not. But that means "once you start shivering, that's your brain telling your body it's time to get to a place where you're warmer." The spasmodic contracting and relaxing of your muscles "consumes calories, and it generates heat" to replace the heat your body is losing through convection or conduction, Greenway said. When your skin temperature drops, shivering kicks in to keep your core temperature from falling, too. Think of shivering as a warning sign that you need to get yourself someplace warmer, fast. ![]()
