The immune system is our first line of defense against the hordes of microbes that threaten us constantly. Just like our heart and our lungs, it works around the clock to keep us alive—and with the advent of coronavirus, no one can take it for granted. Immunity answers the question everyone is asking now: What can I do to strengthen my immune system? Dr. Jenna Macciochi has studied the interplay of immunity, lifestyle, and health for over twenty years, and her book is filled with authoritative guidance on:



● the best foods to eat to boost your immune system



● the importance of movement, and how often to exercise



● the essential link between immunity and sleep



● its surprising connection to your mental health.



Dr. Macciochi also debunks common myths, explores why some people never get ill, and explains how germs—those pesky invaders—can actually be good for us. The immune system is the foundation of your health . . . and Immunity is your essential handbook to staying well in the modern world.
