About this listen
This is an audiobook version of this book.
A world-renowned scientist offers a much-needed analysis of what it takes to have good immune health—helping listeners navigate what can really help, what is a complete myth, and why.
Does orange juice help ward off colds? And how does our age affect our ability to recover from one? When it comes to immunity, are we really what we eat? Or how much we eat? We are surrounded by big questions and big claims about enhancing our immune systems, so how do we tell the fiction from the facts? And, ultimately, what can we do to reduce our chances of getting sick?
World-leading immunologist Daniel M. Davis offers answers in this authoritative, highly accessible, myth-busting guide to the effects of stress, age, exercise, weight, nutrition, sleep, vaccines, and mental health on our immune health. Taking us to the cutting edge of immunology research and explaining both what we know and how we know it, Self-Defense helps listeners spot phony claims and make informed choices. Davis shows us that everyone’s immune system is entirely unique, and that’s why we should be wary of one-size-fits-all “cures.” We learn how exercise, for example, has all sorts of different, even opposing, short- and long-term effects on our immune health. And while our gut microbes are vitally important, it’s unlikely that yogurt drinks can really boost your immune system to stop you getting ill.
An eye-opening window into some of the astonishing possibilities for the future, when it comes to distinguishing bogus and beneficial health claims about everything from vitamin D to inflammation and cancer therapies, Davis’s book may be your best self-defense.

“This book is a masterclass in science communication. Davis unravels one of the most complex and vital elements of human biology, our immune system. Self-Defense disentangles the science of immunity and addresses some of the key questions we all want answered. Does orange juice really help us fight off colds, prevent us getting cancer, or combat HIV? Do increased infections in early childhood protect against allergies, and is it true that children who grow up on farms are less likely to have asthma and hay fever? How might our genes or gut bacteria alter our vulnerability to infection? What is the link between obesity, stress, and sleep with our ability to fight infection? And does our immune system affect our mental health and the aging process? This is essential reading for anybody who wants to understand their health.”—Russell Foster, neuroscientist and author of Sunday Times-bestselling “Life Time”
“Self-Defense: A Myth-Busting Guide to Immune Health uncovers how curiosity-driven science can help you truly understand and optimize your immune system—free from hype, misconceptions, and the traps of mistaking coincidence for causation. From the surprising links between cytokines and mood to the effects of stress on immunity, this book reveals how our biology shapes us in unexpected ways. With stories like how a glowing jellyfish transformed medical research, it shows how simple discoveries can lead to profound insights. Dive in to see how thoughtful, evidence-based exploration can lead to better health, resilience, and self-awareness.”—Roger Highfield, science director at the Science Museum Group (London) and coauthor "The Dance of Life"
“A fascinating guide to the immune system, cutting through the myths with clear, evidence-based science. Davis empowers readers to make informed choices about their health in a world of so much misinformation.”—Rhiannon Lambert, award-winning nutritionist (@rhitrition), co-host of The Wellness Scoop with Deliciously Ella, and Sunday Times-bestselling author of “The Science of Nutrition”
