WIn this episode we will:Break down the four separable pillars of sleep health: duration, consistency, continuity, and circadian alignmentWalk through the landmark UK Biobank study showing sleep regularity outpredicting duration for all-cause mortalityBring in brand-new data from SLEEP 2026 in Baltimore linking sleep consistency to long-term cardiovascular trajectoriesExpose the "range restriction trap," why duration looks less important in these studies largely because almost nobody in them was severely sleep-deprived for years on endStress-test the theory with five hypothetical sleepers, each excelling at one dimension and failing at another, to figure out which variable really wins when you push it to the extremeTo find out more about this week's podcast sponsor Welltory, please use the following link: https://welltory.com/Original intro music Vigilanteology by Abhinav Singh (copyright 2026) Original outro music Vigilanteology (reprise) by Abhinav Singh (copyright 2026)Produced by: Maeve WinterMusic by: Dr. Abhinav Singh (@sleep_vigilante), all rights reservedMoreTwitter: @drchriswinterIG: @drchriwinterThreads: @drchriswinterBluesky: @drchriswinterThe Sleep Solution and The Rested ChildThanks for listening and sleep well!
