Four Easy Ways to Combat Colds

Cold season is upon us. And while the flu shot is great for protecting against the flu, most of the respiratory infections that plague people during the winter are caused by cold viruses, not flu viruses. Unfortunately, there’s no vaccine against the common cold, and antibiotics don’t help because colds are caused by viruses. That’s why it’s helpful to know how to prevent catching the latest cold — and how to effectively fight any colds you succumb to.

Here are four ways to stay healthy this cold season:

Supplement with Vitamin D. Winter is a prime time for Vitamin D levels to plummet. After all, Vitamin D is the sunshine vitamin, and winter is when sunlight is at its weakest and least frequent — not to mention that temperatures are often cold enough that people just don’t spend as much time outside. Unfortunately, winter is also prime time for colds, and lower levels of Vitamin D can negatively impact your body’s ability to fight off infection. There’s an upside, though: Supplementing with a daily dose of Vitamin D can help reduce the risk of respiratory infection, particularly in people with lower levels of the vitamin in their blood.

Get enough sleep. A study published in JAMA Internal Medicine found that those who were sleep deprived were less able to fight off a cold virus compared to those who had sufficient sleep. When participants in the study were exposed to a cold virus, researchers found that those who had gotten less than seven hours of sleep were almost three times more likely to develop a cold compared to those who had gotten eight or more hours of sleep each night.

Eat a colorful diet. Numerous studies have found a link between the body’s ability to fight off colds and consumption of a variety of fruits and vegetables and the nutrients (like antioxidants) they contain. According to the Harvard School of Public Health, there are least nine different families of fruits and vegetables, with each family providing a variety of different plant compounds that are beneficial to human health. One easy way to ensure you’re maximizing the variety of vitamins, minerals, and other beneficial plant chemicals in your diet is by eating a rainbow assortment of fruits and vegetables. Consuming a variety of colors on a daily basis will also help ensure you meet the five-a-day goal!

Disinfect your phone. Because most people touch their phone dozens of times throughout the day, there are many opportunities for phones to pick up germs — so much so that a study at the University of Arizona found 10 times more bacteria on cell phones than on toilet seats! Phones are particularly problematic when it comes to transferring pathogens because people’s phones are often in contact with their faces. Fortunately, the problem is easy to fix: Disinfect your phone weekly using a clean cloth dampened with a mix of 60% water and 40% rubbing alcohol. Also, be sure to clean your phone if other people touch it, and use a hands-free headset whenever possible.
