Your Nervous System Was Never Meant to Be This Busy
There's a reason you feel different after a walk outside - and in this episode, I'm getting into exactly why. I've always known that being outside makes me feel better. I feel it on my morning walks, I feel it when I sit near trees, I feel it the second I step outside instead of sitting at my computer. But I wanted to actually understand what's happening in the body, so I did the research and honestly, the science is wild.
We're talking about what's really going on with your nervous system when you're in nature, why your eyes are literally hardwired to find fractal patterns in trees calming, what forest bathing does to your immune cells (the NK cell study genuinely stopped me), and why barefoot on grass isn't just a vibe - it's measurable. I also share what I think is the deeper truth underneath all of it: you don't need to go be in nature. You are nature. Returning to it is really just coming home.
Plus I share a simple weekly prescription - nothing extreme, nothing that requires a wellness retreat - just what the research actually shows is enough to move the needle on cortisol and HRV.
