What does immunity mean to you? In today’s Feel Better Live More podcast, researcher and lecturer, Dr Jenna Macciochi explains that it’s not just about fighting off infection. Our immune systems do not lie dormant, waiting to wage war if bacteria or viruses invade – they play a central and constant role as our bodies’ housekeepers.
How do we do that? From empowering nutrition advice to insights into how our metabolism and immune systems interact, there’s plenty of practical takeaway from this conversation. We discuss the disruptive effects of stress and how cortisol dampens immunity and even reactivates viruses. Having learned this first-hand when chronic stress led to her getting pneumonia, Jenna shares some helpful rituals for reducing the impact of stress in your life.
Perhaps most fascinating though, is the idea that the type of person you are can shape your immunity. Jenna explains there are five main personality categories and each of them have specific immunological features. Traits and behaviours typical of each category, such as risk taking, sociability and how we respond to stress, can end up informing how our immune systems develop. As we discuss, ‘It’s more important to know what person the disease has than what disease the person has.’
This is a valuable conversation for anyone who wants to understand more about their immune system, not just to reduce their risk of getting an infection, but also to increase their overall wellbeing and longevity.
