#229 - The Health Consequences of a Single Bad Night of Sleep: The Price That We All Pay

A Deakin University study claims one sleepless night cuts muscle protein synthesis by 18%, drops testosterone by 24%, and raises cortisol by 21%. It sounds alarming, until you learn that testosterone already falls about that much every afternoon and most of these changes reset after one good night. In this episode we look at five well-designed studies on what one bad night really does, and which effects actually matter. In this episode we will: Put the Deakin study’s testosterone, cortisol and muscle numbers next to what the body does on a normal day Look at a four-hour night and the one effect that doesn’t fully reset by morning: a primed immune system Revisit the “one all-nighter builds Alzheimer’s amyloid” headline and why researchers pushed back Dig into the effects you feel the next day, including a roughly 30% jump in anxiety Land on the real danger: 17 to 19 hours awake can impair you about as much as a 0.05% blood alcohol level Touch upon what you can do to offset these effects To find out more about this week’s podcast sponsor SideSleeperZ, please use the following link: https://sidesleeperz.com/ Original intro music Vigilanteology by Abhinav Singh (copyright 2026) Original outro music Vigilanteology (reprise) by Abhinav Singh (copyright 2026) Produced by: Maeve Winter Music by: Dr. Abhinav Singh (@sleep_vigilante), all rights reserved More Twitter: @drchriswinter IG: @drchriwinter Threads: @drchriswinter Bluesky: @drchriswinter The Sleep Solution and The Rested Child Thanks for listening and sleep well!
