Summary

In this episode of Revolution Health Radio, Chris challenges the conventional focus on sleep duration and makes the case that sleep timing and circadian alignment matter just as much—if not more—than total hours slept. Drawing on new research, he explains how circadian disruption underlies poor sleep quality, chronic fatigue, and a wide range of mental health conditions, even in people who appear to be doing everything “right.” He explains why light exposure, sleep-wake consistency, and meal timing are the primary drivers of restorative sleep, why adolescents are uniquely vulnerable to sleep-related mental health risks, and shares practical strategies to improve sleep naturally and when supplements may be helpful.

Today we're going to talk about sleep, but not the way you've probably heard before.

1:18.6

We're not going to focus on how many hours you're getting. Instead, I want to talk about something

1:23.3

I think could be more important for most people, which is when you're sleeping relative to your

internal biological clock. This is the circadian piece of sleep that doesn't get nearly

enough attention in mainstream conversations about sleep health. When I was in practice, I worked

with a lot of people who were doing everything right according to conventional sleep advice.

1:43.5

They were getting seven or eight

hours in bed, sleeping in a dark room, avoiding screens an hour before bed, etc. And yet they often
