Can cold weather actually make you sick? Health and safety dangers to know about this winter.

As millions of Americans cope with severe winter weather spread across the country, experts say to watch out for health and safety dangers that go along with frigid temperatures and snow. 

"One of the things we've been seeing in the last couple days is just a lot of falls," Dr. Steve Dorsey, assistant medical director at the Cleveland Clinic emergency department, told CBS News, saying to watch out for icy sidewalks and be careful shoveling snow. "There's clearly an association between the exertion of clearing snow and provoking chest pain or angina."

The cold can also weaken our immune system, increasing the risk of contracting colds, COVID, flu and other illnesses around this time of year.
