We aren't out of cold and flu season quite yet. Fighting the common cold has always been a struggle. You know the drill when it comes to preventing colds: Wash your hands, keep yourself hydrated, get plenty of rest, eat healthy, and get plenty of exercise. But once you get that nasty little bugger, how do you get rid of it? Well, there is always the popular vitamin C. Then zinc became popular as the "new" vitamin C. But, according to CNNHealth.com, the new popular choice is vitamin D. If you are like me and tend to get respiratory tract infections and coughs, this might be just be the vitamin for you. According to the article, vitamin D can protect people with asthma and other chronic lung conditions from colds and infections. The article also says that vitamin D, known as "the sunshine vitamin," acts as a hormone in the body and can help control the immune system, fight cancer, improve cardiovascular health, and regulate blood sugar. So, with the days getting longer and the sun shining more in these chilly, pre-spring days, it's beneficial to your health to go for a brisk walk to soak up those rays. Another way to incorporate more vitamin D into your diet is to eat plenty of fish, milk, shrimp, and eggs. If those foods aren't appealing, you can always take a daily supplement.
