Exercising in the Cold
Cold weather doesn't have to put a freeze on your outdoor exercise program. If you're careful, you can still work out when the weather turns chilly.
Wear the right clothing
Clothing is critical. Although a double-thick cotton sweatshirt may seem like a good choice, it doesn't insulate nearly as well as synthetic fabrics like lightweight polyester, polypropylene, or moisture-wicking materials.
Don't overdress. You can overheat even in below-freezing temperatures. If you dress too warmly, you'll sweat a lot. Then, when cold winds hit, perspiration will rapidly evaporate, chilling you. You want to limit perspiration and keep it away from both your skin and the outside air.
Layering is key
Wear a synthetic material against your skin. This will let the sweat pass through the fabric away from your body. The second layer should be wool, polyester, or fleece for primary insulation. The third layer should be chosen for its ability to keep out the cold air, wind, and rain. This layer should be something lightweight and synthetic.
Layering also helps regulate your temperature. If you get too warm, you can strip off a layer.
You can lose a tremendous amount of heat through your uncovered head, so wear a hat, cap, or hood.
Your feet get cold first. Wear the right boots or shoes. Insulate them with warm socks and keep them dry.
Because of the large surface area to volume, your hands are also more susceptible to cold. Gloves or mittens should be worn before the hands become cold. Choose mittens over gloves, because the fingers can warm each other and the mitten decreases the exposed surface area.
Don't forget fluids
If you can see your breath, you're seeing moisture leave your body. So drink plenty of fluids, particularly if the air is cold and dry. Drink water before you go out, and bring some with you. Don't drink alcohol. Alcohol makes you lose heat.
Don't overdo it
Cold is a stress on the body, and so is exercise. Together they may be too much for someone not in the best of health. Talk to your healthcare provider before you start a winter exercise program.
People who have diabetes, take certain medicines, or are older adults are at greater risk that their body temperature will drop in cold weather.
Other cold-weather tips
Here are other things to consider:
Warming up before exercising is always important, but even more so when it gets cold.
If you drive to where you are exercising, make sure your car is equipped with emergency supplies, such as blankets and a portable charger.
If the weather is particularly cold, it's probably too cold for you to exercise outdoors. If you do have to go out in extreme cold, cover all exposed skin to prevent frostbite. Know the symptoms of hypothermia, such as shivering, tiredness, paleness, and confusion,
Cold air doesn't damage the lungs. Even very cold air is warmed to body temperature by the time it hits the lungs. But for some people with asthma, cold air can trigger an attack.
