183: The Neuroscience Behind Doomscrolling

In this episode of the Health Upgrade Podcast, I dive into the science behind doomscrolling, from why we get stuck endlessly on our phones late at night to what’s really happening inside our brains and bodies during those scrolling marathons. I explore the neuroscience of decision fatigue, explain how our visual systems and nervous states are affected, and uncover how screen habits send us into stress mode instead of helping us truly wind down.

One concept discussed was the powerful link between our visual focus and nervous system state, illustrating how narrowing our gaze on our phones turns off the calming vagus nerve and ramps up stress hormones. I also share practical strategies like the 20-20-20 rule, physiologic sigh breathing, and creating tech boundaries in the evening to support better sleep and healthier habits.
