Cold weather brings about the common misconception that rehydration during exercise isn't as important as during hot weather. While it's true that typical sweat losses are reduced in cooler weather, the additional clothing worn during winter sports actually contributes to significant fluid and electrolyte loss via sweat. Cold weather studies at the University of New Hampshire, in fact, confirm an increased risk for dehydration.
“People just don’t feel as thirsty when the weather is cold,” says Robert Kenefick, UNH associate professor of kinesiology. “When they don’t feel thirsty, they don’t drink as much, and this can cause dehydration.” Robert Kenefick’s cold weather study, published in the journal Medicine & Science in Sports & Exercise, had participants exercise on treadmills in cold chambers and found the participant’s thirst sensation to be reduced by as much as 40 percent. Kenefick concluded that this result is due to our bodies naturally decreasing outward...
