The truth behind 4 winter health myths

Winter often brings a flurry of health advice — some helpful, and some based on longstanding myths. 

Learn the truth behind some common winter health myths:

Myth: You can skip sunscreen in the winter 

Fact: You might diligently apply sunscreen on those lazy summer days at the pool, but don’t pack it away with your swimsuit.  

There are many reasons why it’s important to use sunscreen in the winter months. For example, the sun might not be shining as often, but UV rays can penetrate clouds on those overcast wintery days. It’s also important to wear sunscreen when there’s snow on the ground.  

“Sunlight reflects up on fresh snow, essentially doubling your sun exposure,” says Dr. Edmund Fernandez, a family medicine physician at Aurora Health Care. 

Myth: It’s too cold to exercise outdoors 

Fact: There are many health benefits to exercising outdoors during the winter, such as exposure to natural sunlight which can help boost your mood and vitamin D levels. Taking your workout outdoors also can help improve endurance and burn calories. 

“When you exercise outside in cold weather, your body works harder to stay warm. This can increase your energy levels and burn fat,” says Dr. Fernandez. 

It’s important to still dress appropriately for the weather by wearing many layers.

Myth: Frostbite isn’t common 

Fact: While frostbite isn’t an everyday occurrence for most people, it can be a real danger. Wet or cold skin can numb within half an hour, even if temperatures are just above freezing. Commonly affected areas include exposed fingers, toes, nose, ears and cheeks. 

“Dressing in layers, staying dry and limiting how long you’re exposed to freezing temperature can help prevent frostbite,” says Dr. Fernandez. 

Myth: Going outside with wet hair can make you sick 

Fact: You might have ice particles form in your wet hair, but going outside with wet hair in the winter shouldn’t make you sick. Instead, it’s exposure to germs that can cause illness. 

“Illnesses like colds and flu are caused by viruses, not by being cold or having wet hair. However, wet hair can make you feel colder, which might lower your comfort level and cause mild stress on your body,” Dr. Fernandez says.
