It’s cold season. I hear people sneezing on the train, people sniffling at the office and coughing as they are walking down the street. You can’t avoid it. According to John Hopkins Medicine, the average adult gets 2-4 upper respiratory infections per year. We are constantly being exposed to millions of germs on a daily basis. Our immune system, is just that a system, that works to combat the germs and fight against infections.
In the past decade there have a number of studies looking at the effects of physical activity on immune function. While exercise is known to be beneficial for helping control and prevent a number of age related ailments and disease, this is a relatively new subject to be researched. One’s overall immune function is mostly genetic but the average adult’s immune defense does varies from day to day based on lifestyle choices. Vitamins, supplements and basic dietary choices can help promote a healthy immune response. Sleep plays an important role and not surprisingly, the amount of stress in your daily life can also negatively effect your ability to fight off a cold.
So what about exercise? It is one of the lifestyle choice that appears to be helping immune function. This shouldn’t be too shocking as moderate exercise is also helpful with dealing with stress and anxiety. Just another reason to be getting in those daily physical activity minutes! But studies show that too much can start having an opposite effect. Intense exercise, labeled at more than hour and half of sustained physical activity (i.e. marathon runners, professional athletes) can weaken your ability to combat viruses. Many athletes are more susceptible to getting sick after a big competition where they were training for extended periods of time. So unless you are a professional, like for so many things in life, moderation is key.
