Exercising may be able to help you fight a cold more efficiently. A recent study has shown that frequent exercise could be the key to building up a healthier immune system. “…our immune system reacts to invading microbes through a variety of cells. Some of these cells don’t directly combat the infection, but instead promote the development of inflammation…Scientists have long tried to determine why inflammation sometimes grows rampant in the body. One thing they’ve noticed is that fat cells are particularly adept at producing substances that promote inflammation…[which] can lead to…a weaker overall immune response to an infection or illness.” Regular exercise promotes positive inflammation in the body—through the healing and growth of muscles—and decreases the likelihood of excessive negative inflammation that can lead to colds, flus, and other infections
