You know the importance of drinking plenty of water while exercising during hot weather. But it's just as important to keep the water flowing during the winter months.

When exercising in cold weather, you lose water from sweating and breathing - when you "see" your breath, you're seeing water droplets that your body uses to warm the cold air you're inhaling. Cold also stimulates urine production.

So, to avoid dehydration, drink even if you don't feel thirsty.
