What if spending time in nature isn’t simply good for you, but something your brain is biologically designed to need?
In this solo episode, Darin explores the sensory neuroscience of nature and the growing research suggesting that our increasingly indoor lives may be fundamentally mismatched with the environments our brains and nervous systems evolved to experience. From walls and screens to fluorescent lights, traffic, right angles, and constant notifications, modern environments bombard us with sensory inputs our ancestors never encountered at this scale.
The numbers put that mismatch into perspective. Darin highlights research suggesting the average American spends roughly 87% of life indoors and another 6% inside vehicles. In other words, we’ve effectively become an indoor species living inside outdoor-evolved bodies, brains, eyes, and nervous systems.
Darin breaks down why this isn’t merely another reminder to “go outside.” He explores how modern environments place continuous demands on executive attention, why sustained attention can eventually give way to rumination and mental chatter, and what more than 100 brain-imaging studies may reveal about what happens when we finally return our brains to natural environments.
This episode ultimately asks a surprisingly important question: What if nature isn’t a luxury or lifestyle preference, but a biological input we’ve slowly removed from our lives?
