What is “normal” aging? Which changes are a normal part of getting older, and when should you be more concerned? In this episode of Health Recoded, we break down healthy aging and what happens to the body as we get older. Aging affects nearly every system in the body, but not every change should simply be dismissed as “getting old.” We discuss how aging affects the brain, muscles, bones, skin, energy, and recovery, as well as when fatigue, aches, and other changes may be worth paying attention to. We also discuss how strength training and physical activity can support healthy aging, whether vitamins and supplements can prevent aging, and the difference between lifespan and healthspan. If you're noticing changes in your energy, recovery, strength, memory, or physical health as you get older, this episode gives you a place to start understanding what may be part of normal aging and what may deserve further attention.
