Building a strong immune system is not just about popping vitamin supplements or diffusing your favorite immune building oils. It’s a deeper, more involved approach that includes decisions to nurture the body and mind through interwoven aspects. We’ll call them “pillars” for the purpose of this post. Your immune system pillars are: sleep, exercise, healthy eating, and psychosocial well-being. Creating an intentional care plan for each of these areas will help you strengthen your immune system and prep your body for its best defense.
