HSOS #38: Move Your Body, Save Your Brain: How Exercise Protects Your Brain from Dementia (Part 2)

Your brain is literally begging you to move, and in this episode, Kim delivers the science behind why in the most compelling, relatable way possible. Picking up right where Episode 37 left off, she digs into the powerful research connecting exercise to a dramatically lower risk of dementia and Alzheimer's, and breaks down exactly what is happening inside your body when you sweat, lift, and even just take a walk around the block. From a little something called "Miracle-Gro for your brain" to why Alzheimer's is being called Type 3 Diabetes by some researchers, this episode will have you lacing up your sneakers before it's even over. Consider this your science-backed permission slip to move your body like your brain depends on it, because it actually does.Let's talk.Welcome to Her Season of Strength, where women over 40 reclaim their bodies, their energy, and their voices, without apologies.
