Being sick for a while because you are “coming down with something” is no big deal. In fact, it’s a healthy healing response. But if an infection persists, or if you suffer from recurring infections, it is a sign that your immune system is not working properly. This can happen for many reasons. An unhealthy lifestyle, nutritional deficiencies, a lack of physical activity, too much stress, not enough sleep, the use of certain medications, and various other conditions can undermine the functioning of the immune system.
To strengthen your immunity, you must first make changes to your diet and lifestyle to restore the overall health of your body. To support this process, you can take a number of immune-boosting supplements.
