Marathon_10-19-09_EH.JPGThe onset of winter weather can trick runners into dehydration, writes Kim Mueller, a registered sports dietitian and competitive endurance athlete who provides nutritional counseling and meal planning to athletes all around the world.

Even in the coldest weather, runners need to drink, she wrote in a bulletin published by the Berkeley Running Company, a store in Madison, Wis.

"During the fall and winter months, athletes can be tricked into performance declines associated with dehydration," she wrote. "As the cooling effect of air and rain sometimes mask our sense of fluid loss, many athletes fail to take into account the significant amount of water loss that is still occurring. The risk is compounded when runners layer their body with excessive clothing, thereby increasing fluid loss. In fact, fluid deficits of 3 to 8 percent of total body mass have been reported in individuals working in cold environments. So, despite many athletes perception that dehydration is a problem that exists only during the summer months, it is quite possible to run yourself dry as the thermometer drops. Join me as we explore water's role in human performance and address how you can maintain peak performance through proper hydration."
