New York doctor gives 5 tips for staying active outdoors during the cold winter months

 Winter is in full swing in most parts of the country and the low temperatures have made it more difficult to step out and enjoy the fresh air.

Millions of Americans prefer to get their exercise outside — which can be difficult when the temperatures drop.

Dr. Alexis Colvin, professor of orthopedic surgery at Mount Sinai Health System in New York City, shared with Fox News Digital some tips for continuing outdoor exercise even in the colder months.

Read on for her tips and insights for staying fit and active this season.

1. Dress appropriately

"For winter activities, layered clothing helps adjust to changes in body temperature as you begin to warm up, manage moisture as you sweat and protect against wind, snow, rain and cold," He said.

The orthopedic surgeon, who specializes in knee, shoulder and hip disorders, said the base layer of clothing should be moisture-wicking material, followed by a middle layer of insulation and the outer layer should be breathable and waterproof.

He also said people who choose to exercise outside in cold temperatures should consider using hand and foot warmers.

"The heat subsides first in these areas," he said.

2. Be weather cautious

Cold air can sometimes trigger asthma, he said, which can be potentially harmful for those exercising outside.

"To prevent this, warm up indoors and cover your nose and mouth with a gaiter, scarf or mask when you go out," he said.

Colvin also suggested taking a day of rest if it was too cold or the weather was bad nearby.

3. Warm up inside

It's important to make sure your body is warm and ready to expel lots of energy before you leave the house, Colvin said.

“A 10-15 minute warm-up before going out for exercise is important to prepare your body,” he said.     

Colvin, who is also the chief medical officer for the US Open, gave examples of simple exercises such as arm circles, high knees and jumping jacks — which "activate large muscle groups and increase your heart rate."     

4. Take long walks

"If it's hard to find the motivation to do a full workout, try a long walk," she said.

If you live somewhere cold enough that it snows a lot, try using the elements as recommended by your doctor.

Take the opportunity to try new types of workouts, like cross-country or downhill skiing, snowshoeing, or ice skating.

"Or a competitive snowball fight!" He added.

5. Wear the right shoes

Colvin's fifth tip was that no matter what exercise you want to do outside, make sure you're prepared in the shoe department.

“Shoes with good traction are essential to prevent injuries from slipping on icy surfaces,” he said.

Colvin said it's also important to use caution when walking on icy sidewalks, stairs or roads.
