Here are four tips to improve your immunity: 1) Sugar: Cut out or significantly reduce refined sugars. Sugar from fruit is NOT the same: fruit also contains antioxidants, nutrients and fiber. 2) Exercise: Movement helps oxygenate and move your blood and lymph. Do whatever you enjoy! Outdoor air will also invigorate you and refresh your lungs. 3) Vitamin D: Getting enough D allows your white blood cells to keep up, especially during times when your body may require more such as in fall and winter. 4) Vitamin C: Eat more fresh fruit and vegetables, and supplement as needed. This vitamin helps prevent sickness and speeds recovery.
