Winter Fitness: Safety tips for exercising outdoors

Winter Fitness:  Safety tips for exercising outdoorsDressing in layers, protecting your hands and feet, and paying attention to the forecast can help you stay safe and warm while exercising outdoors in cold weather.

Frigid temperatures can discourage even the most motivated exercisers. Without motivation, it’s easy to pack away your  workout gear for the winter. But you don’t have to let cold weather spell the end of your fitness routine. Try these tips for exercising during cold weather to stay fit, motivated and warm.

Stay safe during cold-weather exercise
Exercise is safe for almost everyone, even in cold weather. But if you have certain conditions, such as asthma, heart problems or Raynaud’s disease, check with your doctor first to review any special precautions you need based on your condition or your medications.

The following tips can help you stay safe — and warm — while exercising in the cold.

Check weather conditions and wind chill
Check the forecast before heading outside. Temperature, wind and moisture, along with the length of time that you’ll be outside, are key factors in planning a safe cold-weather workout.
Wind and cold together make up the wind chill, a common element in winter weather forecasts. Wind chill extremes can make exercising outdoors unsafe even with warm clothing.

The wind can penetrate your clothes and remove the insulating layer of warm air that surrounds your body. Any exposed skin is vulnerable to frostbite.

The risk of frostbite is less than 5 percent when the air temperature is above 5 F (minus 15 C), but the risk rises as the wind chill falls. At wind chill levels below minus 18 F, frostbite can occur on exposed skin in 30 minutes or less.

If the temperature dips below 0 F or the wind chill is extreme, consider taking a break or choosing an indoor exercise instead. Consider putting off your workout if it’s raining or snowing unless you have waterproof gear.

Getting wet makes you more vulnerable to the cold. And if you get soaked, you may not be able to keep your core body temperature high enough.

Know the signs of frostbite and hypothermia
Frostbite is an injury to the body that is caused by freezing. Frostbite is most common on exposed skin, such as your cheeks, nose and ears. It can also occur on hands and feet. Early warning signs include numbness, loss of feeling or a stinging sensation.

Immediately get out of the cold if you suspect frostbite. Slowly warm the affected area — but don’t rub it since that can damage your skin. Seek emergency care if numbness doesn’t go away.

Hypothermia is abnormally low body temperature. When exposed to cold temperatures, your body begins to lose heat faster than it can be produced. Exercising in cold, rainy weather increases the risk of hypothermia. Older adults and young children are also at greater risk.

Hypothermia signs and symptoms include intense shivering, slurred speech, loss of coordination and fatigue. Seek emergency help right away for possible hypothermia.

Dress in layers
Dressing too warmly is a big mistake when exercising in cold weather. Exercise generates a considerable amount of heat — enough to make you feel like it’s much warmer than it really is. The evaporation of sweat, however, pulls heat from your body and you feel chilled. The solution?

Dress in layers that you can remove as soon as you start to sweat and then put back on as needed. First, put on a thin layer of synthetic material, such as polypropylene, which draws sweat away from your body. Avoid cotton, which stays wet next to your skin.

Next, add a layer of fleece or wool for insulation. Top this with a waterproof, breathable outer layer.

You may need to experiment to find the right combination of clothing for you based on your exercise intensity. If you’re lean, you may need more insulation than someone who is heavier.

Keep in mind that stop-and-go activities, such as mixing walking with running, can make you more vulnerable to the cold if you repeatedly work up a sweat and then get chilly.
