There are endless winter health myths that we have heard from well-intentioned grandparents and parents. They have become so ingrained in us that we take them as cold hard facts. Many of these myths have no more basis in reality than Santa Claus.  Of course, everyone wants to stay as healthy as possible during the frosty months. In order to do so sensibly, we turned to Board Certified NYC internist and gastroenterologist Dr. Niket Sonpal.

Myth: I wash my hands all the time with hand sanitizer, so I should be fine.
Hand sanitizer will kill most viruses, but not all. You must make sure you use the right amount of hand sanitizer and let it dry completely. Dr. Sonpal points out that,” Some viruses, like norovirus, which causes vomiting, is not killed by hand sanitizer. Soap and water are best to get rid of all bacteria and viruses, but the hand sanitizer is better than nothing at all.”

Myth: It’s cold out, I don’t need sunscreen.
The sun’s rays are just as strong in the winter months as they are in the other seasons. Snow and ice can reflect even more sunlight, up to twice as much. Grab the SPF 30 and put it on, regardless of the temperature. Don’t forget those sunglasses to keep your eyes safe as well.

Myth: Winter weather makes you store fat and gain weight
Our bodies do not go into some kind of winter hibernation mode, stockpiling every ounce of fat to use for the lean times. It seems logical, like a throwback to our days living in caves foraging for food, but in reality, any weight gain comes from our winter habits. Dr. Sonpal points out that, “we tend to exercise less in winter. We eat more hearty meals and comfort foods, including more sugary snacks and desserts (especially around the holidays).”

Myth: You Lose Most Heat Through Your Head
The saying goes “we lose 90 percent of our body heat through our heads.”  But a 2006 study found that the head accounts for about 7 percent of the body’s surface area, and that heat loss in the region is fairly proportional, according to LiveScience. “Your head is another extremity, and it’s susceptible to cold, so you should wear a hat, but it doesn’t lose any more heat than another part of your body,” says Dr. Sonpal.

Myth: Chicken Soup Will Cure Colds
Many cultures teach us to drink warm liquids like tea, hot apple cider, and soups when we’re dealing with colds. It’s true that something like chicken soup may help soothe and ease congestion, but much like vitamin C, hot soup won’t do immediate wonders.
