Many people feel as though they visit their physicians more frequently for colds and viruses in the winter than in any other season. Indeed, seasonal illnesses have been around for centuries, with the link between weather patterns and sickness dating as far back as ancient Greece. The weather could definitely be affecting the way your immune system works.

The Impact of Cold Weather on Your Immune System

Does Cold Weather Impair Immunity?

Until recently, physicians credited behavioral patterns with the spike in illnesses during the winter months. After all, people tend to spend more time indoors and in the company of others, which could contribute to the exchange of germs. Nonetheless, recent research shows the uptick is actually suspected to result from the way cold temperatures affect immunity.

Specifically, researchers have discovered that lower temperatures weaken the nose’s immune defenses. In animal studies, mice exposed to rhinoviruses were less successful at fighting off the illness in cooler temperatures. When temperatures are warm, cells effectively create a defense against illnesses and create antiviral properties. In colder conditions, the response is much weaker.

What Can I Do to Stay Healthy?

The first line of defense for avoiding illnesses this winter is to visit your physician for a flu shot. In addition to the body’s impaired ability to fight off infections in cold weather, flu season, which runs from October through May, presents an added wintertime threat. In its most severe cases, it could lead to serious complications, such as pneumonia and dehydration—especially in seniors and children. Thus, it is recommended everyone over the age of six months who does not have a known allergy to the vaccine receive the flu shot.

In addition, washing your hands regularly is a good way to prevent the spread of germs. This is especially important in shared environments, such as work places, gyms, and shopping centers. Avoid getting close to people who are sick. Lastly, boost your immune system by eating healthy meals made from natural, nutrient-rich food sources and exercising regularly.
