In this gripping episode of Science Unlocked, we go inside the quiet biological phenomenon called inflammaging—a low-grade, chronic inflammation that quietly speeds up aging from the inside out. If you're 50 or older, or even close to it, this smoldering ember might already be in effect in your body, quietly breaking down your energy, memory, muscle mass, skin texture, and even your heart health. From the initial warning signs of fatigue and brain fog to the catastrophic impact on your immune system and organs, this video deconstructs the 10 progressive stages of inflammaging, describing what they feel like, how they appear, and what's going on behind the scenes. Employing rich analogies and actual biological processes, we illustrate how inflammaging progressively rewrote the playbooks of your body's performance—and what to do to put a halt to it. Whatever your reason for wanting to boost energy, ward off age-related disease, or just get to know your body better, this is the most vital health deep dive you'll see this year.
