This episode dismantles the decades-old "Open Window" theory that claimed hard exercise destroys your immune system. Based on a landmark 2018 systematic review, we reveal the truth: your immune cells don't die; they are strategically redeployed to your lungs and gut for heightened surveillance. We explore the real culprits behind "Taper Flu." First, the "Let-Down Effect," where the sudden drop in stress hormones during your taper unmasks latent viruses you contracted weeks ago. Second, Psychoneuroimmunology (PNI), which shows how pre-race anxiety crushes your mucosal immunity (salivary IgA), opening the door to infection. Third, the shocking fact that up to 70% of your symptoms may be non-infectious airway inflammation—a "fake" cold caused by mechanical trauma from heavy breathing. Learn the actionable strategies to protect yourself: why you must taper your mind as well as your body, the danger of cutting calories, and how to use sleep and hygiene to arrive at the start line healthy and ready to perform.Keywords: immunology, taper, overtraining, psychoneuroimmunology, cortisol, open window theory, upper respiratory tract infection, marathon, endurance🎙️ Lactate, the podcast that deciphers science to improve your performance.Key references :Campbell, J.
