during cold conditions. Hand coverings should be worn as needed and in extreme conditions, a scarf or facemask should be worn. Mittens are warmer than gloves. Feet can be kept dry by wearing moisture-wicking or wool socks that breathe and should be dried between wears. Energy/Hydration Maintain energy levels via the use of meals, energy snacks and carbohydrate/electrolyte sports drinks. Negative energy balance increases the susceptibility to hypothermia. Stay hydrated, since dehydration affects the body’s ability to regulate temperature and increases the risk of frostbite. Fluids are as important in the cold as in the heat. Avoid alcohol, caffeine, nicotine and other drugs that cause water loss, vasodilatation or vasoconstriction of skin vessels. Fatigue/Exhaustion Fatigue and exhaustion deplete energy reserves. Exertional fatigue and exhaustion increase the susceptibility to hypothermia, as does sleep loss. Warm-Up Warm-up thoroughly and keep warm throughout the practice or competition to prevent a drop in muscle or body temperature. Time the warm-up to lead almost immediately to competition. After competition, add clothing to avoid rapid cooling. Warm extremely cold air with a mask or scarf to prevent bronchospasm. Partner Participants should never train alone. An injury or delay in recognizing early cold exposure symptoms could become lifethreatening if it occurs during a cold-weather workout on an isolated trail. Practice and Competition Sessions The following guidelines, as outlined in the 2008 NATA position statement, can be used in planning activity depending on the windchill temperature. Conditions should be constantly re-evaluated for change in risk, including the presence of precipitation: • 30 degrees Fahrenheit and below: Be aware of the potential for cold injury and notify appropriate personnel of the potential. • 25 degrees Fahrenheit and below: Provide additional protective clothing; cover as much exposed skin as practical; provide opportunities and facilities for re-warming. • 15 degrees Fahrenheit and below: Consider modifying activity to limit exposure or to allow more frequent chances to re-warm. • 0 degrees Fahrenheit and below: Consider terminating or rescheduling activity. Environmental Conditions To identify cold stress conditions, regular measurements of environmental conditions are recommended during cold conditions by referring to the Wind-Chill Equivalent Index (WCEI) (revised November 1, 2001). The WCEI is a useful tool to monitor the air temperature index that measures the heat loss from exposed human skin surfaces. Wind chill is the temperature it “feels like” outside, based on the rate of heat loss from exposed skin caused by the effects of the wind and cold. Wind removes heat from the body in addition to the low ambient temperature. Cold Stress and Cold Exposure When traveling to areas of adverse weather conditions, the following terms will be consistently referred to in weather forecasting. Wind Chill Increased wind speeds accelerate heat loss from exposed skin, and the wind chill is a measure of this effect. No specific rules exist for determining when wind chill becomes dangerous. As a general guideline, the threshold for potentially dangerous wind chill conditions is about minus-20 degrees Fahrenheit. Wind Chill Advisory The National Weather Service issues this product when the wind chill could be life threatening if action is not taken. The criteria for this warning vary from state to state. Wind Chill Factor Increased wind speeds accelerate heat loss from exposed skin. No specific rules exist for determining when wind chill becomes dangerous. As a general rule, the threshold for potentially dangerous wind chill conditions is about minus-20 degrees Fahrenheit. Wind Chill Warning The National Weather Service issues this product when the wind chill is life threatening. The criteria for this warning vary from state to state. Blizzard Warning The National Weather Service issues this product for winter storms with sustained or frequent winds of 35 miles per hour or higher with considerable falling and/or blowing snow that frequently reduces visibility to onequarter of a mile or less. 31
