| 0:05.9 | For years, the conversation around sleep has been almost entirely about duration. |
| 0:10.1 | And that data is still completely valid, but it's incomplete. |
| 0:13.0 | The research now tells us with extraordinary clarity that the consistency with when you sleep matters just as much as how long you sleep. |
| 0:20.0 | You could be sleeping eight hours a night |
| 0:21.8 | and still be dramatically increasing your cardiovascular risk |
| 0:25.0 | simply because you're sleeping those eight hours |

Or I've been telling myself, I'll catch up on the weekends. Is that actually doing anything? And the honest answer to that last question is the reason why we're back here today. I'm biohacker and human biologist Gary Brecker, and you're listening |
| 1:27.8 | to the Ultimate Human Podcast. Since that episode aired, I've been deep in a new stack of research, |
| 1:33.0 | and what came out of that literature in just the past few years has genuinely shifted how I think |
| 1:37.9 | about this, not what we already knew, but a layer underneath it that most people are completely |
