According to current data, the U.S. needs about 52,000 more primary care physicians by 2025 to meet our healthcare needs. And since cold and flu season is approaching with full force, it's important to know what to do -- and what not to do -- to keep sickness at bay. Here are just a few wintertime flu prevention mistakes to steer clear of this season.

Staying Indoors All The Time
It may seem logical to assume that staying inside is the safest way to avoid coming down with something. However, it's important to make the distinction that spending too much time in cramped spaces is what leads to the spread of illness. Frequent walks outdoors -- even in the cold -- can still work wonders to prevent you from succumbing to the flu or common cold. Let yourself and your immune system breathe by spending some time outdoors when you can. And of course, always wash your hands when you return from any public place.

Not Getting A Flu Shot
Many people seem to think that getting a flu shot can actually cause the flu. This is a majorly misinformed myth that can be dangerous if believed. Most people are perfectly safe to get a flu shot, and it can work wonders in keeping you protected against the illness. If you're not sure where to get a flu shot or if it's right for you, consult your local family health care professional or visit a free walk in clinic.

Loading Up On Vitamin C -- But Only Vitamin C
Finally, while it's entirely true that vitamin C can work wonders in warding off the flu and other winter illnesses, it shouldn't be the only supplement you're taking. It's extremely important to get adequate amounts of vitamin D in your diet as well, either through foods themselves or vitamin supplements. Everybody knows that the sun is a major source of vitamin D, but it isn't seen too often during the winter. Do your immune system a favor by prioritizing both of these preventative nutrients.

Ultimately, knowing which methods work to prevent the flu -- as well as which methods don't work -- is the key to keeping you and your family healthy all season long. For more information about preventing illness, stop by your local family health clinic or free walk in clinic. Urgent care facilities are also a viable way to receive family quick care.
