Get Through Cold and Flu Season Unscathed

When you think cold and flu season, you likely think about boosting your immune system. The standard go-to items are vitamin C, vitamin D, and zinc to help you prevent and shorten colds. I would say what’s as important, if not more so, is avoiding those immune busters to begin with.

The aforementioned core items are great at boosting the immune system, but another part of whole-body health is avoiding that which can reduce the immune system. Stress, diet, exercise, and sleep are huge factors in immune health and can be a make or break for avoiding illness in the winter season.
