15. Optimizing Your Glymphatic System to Detox Your Brain While You Sleep

In this episode, Sam explores the glymphatic system (no, not the lymphatic system!) and how it works to detox our brains after we fall asleep. Inspired by a TikTok video, she deep dives into a recent scientific discovery, is shocked to learn about what the brain does to itself while we're unconscious, and shares strategies for optimizing its performance to protect ourselves from cognitive dysfunction as severe as Alzheimer's and dementia. Listen to this episode if you want to geek out with Sam, if you want to learn something new about the way your brain and body work together to protect you, or if you need some motivation to improve the length and quality of your sleep at night.
