    Exercising in Cold Weather

    The weather may be frightful from time to time, but that's no reason to forego outdoor pursuits. If you trade exercise for sitting huddled by the fire there may be a heftier you to get moving come spring.

    Your outdoor running and walking routines don't have to go away when it's cold.

    "Just modify them a little,” says personal trainer Valerie Walkowiak of theLoyola Center for Fitness in Illinois. "Winter can be a great time for outdoor activity if you're prepared."

    The Benefits of Staying Active Year-Round

    Actually, exercising in cold weather offers many advantages.

    Some studies have found that cold-weather exercise helps to transform white fat into the brown fat that burns more calories around the belly and thighs.

    During the winter, some people are affected by a lack of sunshine and may experience a type of depression calledseasonal affective disorder, or SAD. Outdoor exercise exposes you to sunshine, whichmay reduce your risk of developing SAD. 

    According to sports medicine specialistAdam Tenforde, MD, cold-weather exercise may help you build endurance while increasing your ability to work out more intensely.

    “In colder temperatures, your heart doesn’t have to work as hard and you sweat less, which means you can exercise more efficiently,” Tenforde explains.

    So use the cold to your advantage. Running, skiing, snowboarding and cross-country skiing are vigorous workouts that build strength and help improve your cardiopulmonary system.

    In fact, it appears that warm- and cold-weather workouts complement each other.

    According to a University of Oregonstudy, training and working out in warm weather actually helps you perform better at winter sports.

    Cyclists who trained in the heat were able to ride faster and exhibited more aerobic power than those who only trained in the cold.

    Dressing for the Cold

    Dressing in layers is the best advice for working out in cold weather.

    "Avoid heavy coats because when you sweat, you'll feel colder from moisture sitting on the skin. Sweating may also lead to dehydration," says Walkowiak.

    For your upper body, start with a base layer made of synthetic material that allows evaporation of moisture. Cover that with a sweater, then an outer shell or jacket that is wind and waterproof, yet breathable.

    For your lower body, wear a base layer, then add tights that have a fleece lining or ones that have a wind-resistant outer layer.

    Keep your head, hands and neck warm by wearing a fleece or wool scarf.

    Walkowiak recommends footwear with soles that can provide traction on snow, ice or uneven surfaces as well as waterproof outerwear—shoes, hat, gloves—to keep you dry. The hat is especially important; you can lose a lot of body heat through your head.

    Staying Safe During Winter Workouts

    Taking a few simple precautions will help to ensure your safety while exercising in cold weather.

    For starters, always check the weather forecast and plan for changing weather. And don’t forget your pre-workout stretch; cold muscles can be pull-prone.

    It's important for motorists or other people to see you clearly on gloomy days or when running, walking, or cycling in the dark, so wear reflective clothing. To avoid hazards such as icy patches or potholes, wear a headlamp or carry a flashlight.

    Signs of Frostbite and Hypothermia

    Hypothermia results when your temperature drops below 95°; your body loses heat quicker than it can produce it. Signs of mild hypothermia including shivering, teeth chattering and a slight feeling of disorientation.

    Hypothermia can occur in temperatures as warm as 50° for the prolonged periods that you would encounter if you're, say, running a marathon or cycling long distances.

    Signs of moderate hypothermia include slurred speech, increased shivering, a weak pulse and lack of coordination.

    If left unchecked, severe hypothermia can occur. The person stops shivering, breathes very shallowly, becomes extremely disoriented and often loses consciousness. A person suffering from hypothermia must be warmed up; wet clothes should be removed and replaced with dry ones.

    Also be aware of the danger posed byfrostbite, in which skin and underlying tissues begin to freeze; a numb or painful sensation is the first sign.

    Immerse frostbitten extremities in lukewarm, not hot water, and wrap the person in warm blankets. Skin turning white indicates restricted blood flow; if that happens seek medical help.

    To prevent frostbite, always wear a hat, scarf and gloves in very cold weather.

    Also, keep in mind that cold weather doesn't protect you against sunburn.

    "Sunscreen is almost more important in winter than in summer because snow or ice can reflect more than 80% of ultraviolet radiation, compared to between 10% and 15% for water and beach sand in summer, " saysAshi Weeraratna, PhD, of Johns Hopkins University.

    Weeraratna recommends wearing a hat with a brim that provides a protective shadow over the face. And don't forget to protect your lips; using a lip balm with an SPF of at least 15 (30 is even better) can also help prevent painful cold sores around your mouth.

    Know Your Body

    If you're not used to vigorous exercise, winter isn't the best time to start a fitness program unless you have access to an indoor facility. But even if you continue to follow a regular routine, know your limits and listen to your body.

    If your muscles feel tired, you can't keep up your usual pace or you feel thirsty, it's time to reevaluate what you're doing. Cold and wind can zap energy quickly, so find a warming center or indoor area where you can recover.

    "Stay away from caffeine products," Walkowiak advises.

    Although it's tempting to drink a cup of hot coffee or hot chocolate to warm up, caffeine may accelerate dehydration. Drinking water is the best way to stay hydrated and keep the body performing efficiently.

    Walkowiak cautions against eating protein before exercising, as blood will go to your digestive system rather than to your extremities. Because fruit is usually digested within an hour, it's a good snack.

    "After exercise, eat to replenish protein and carbohydrate stores," Walkowiak adds.

    Your immune system also needs protection. Zinc and the probioticS. salivarius K12 help support a healthy upper respiratory tract; arabinogalactans, olive leaf and andrographis support proper immune function.*These statements have not been evaluated by the Food and Drug Administration.

    Instead of using cold temperatures as an excuse to stay inside, get out and enjoy winter's invigorating chill.
