7 Surprising Things You Can Do to Help Prevent Colds

Topics:

It might be called “the common cold,” but there’s nothing common about it. There are more than 200 kinds of viruses that cause colds, and spread from person to person. Not only that, here’s a surprising fact: Cold germs can actually live on surfaces like doorknobs for several hours. 

So how can you defend yourself against colds in the first place? Strengthen your immune system. Here are 7 tips that can help you boost yours with a more surprising approach to cold prevention than you might expect.

  1. Take a Hike. Or a walk, a spin class…Exercise is good for boosting your immune system, which is powered by white blood cells — your body’s defense system against disease. Studies show that being active is beneficial to white blood cells, getting them to circulate more rapidly. A quick 30 minutes of exercise is all it takes!
  2. Watch Your Weight. You already know being overweight can put you at risk for certain health conditions. But it can also cause your body to be in a chronic state of inflammation — and that can make it tougher to fight off infection. Losing weight can give your immune system a chance to fend off colds.
  3. Eat More Yogurt. We know eating foods high in vitamin C helps prevent colds. Another way to give your immune system a boost is by eating yogurt. Researchers suspect that yogurt, which is full of good bacteria, can stimulate production of virus-attacking white blood cells and help the immune system.
  4. Fill Up on Fish. Besides being delicious, seafood is a great choice for fighting illness. The omega-3 fatty acids in fish (especially in fatty salmon and tuna) help your body produce anti-inflammatory substances, which can help immune function. Aim for 2- to 3-ounce servings of fish twice a week.
  5. Soak Up Some Sun. Surprised? Well,your body actually needs exposure to the sun in order to produce vitamin D, and studies show that vitamin D can reduce the risk of respiratory illness. Just 10 - to 15-minute blocks of sun twice a week — without sunscreen — is all you need, according to the National Institutes of Health.
  6. Wash Those Hands. The Center for Disease Control reports that 80% of infectious diseases are spread by touch; that includes touching surfaces where cold germs can live, and then touching your eyes, mouth or nose. When washing your hands, be sure to use soap and water, then rub them together for a minimum of 20 seconds, scrubbing between fingers and under fingernails.
  7. Get Some Sleep. Studies show that a lack of sleep can weaken your immune system, making you more likely to catch a cold when exposed to germs. Here’s why:
    • As you sleep, your immune system produces proteins called cytokines. To fight infection or inflammation, your body needs to increase production of certain types of cytokines. Less sleep means less production. 
    • Lack of sleep also reduces the production of antibodies that fight infection. So, what does “enough sleep” mean? For adults, it means 7 to 8 hours a night; teens need 9-10 hours; kids need 10 or more hours.


BONUS TIP: A daily saline rinse of your nasal passages can keep them moist and help clear out the bacteria, viruses and irritants that can cause a cold. Use a neti pot with a saltwater solution, or try a natural saline spray like ARM & HAMMER™Simply Saline™Instant Relief to irrigate and moisturize your sinus and nasal passages— and to help prevent congestion.


Boosting your immunity is a smart way to help prevent colds. While there are plenty of things you can do, these 7 tips are an easy place to start.
