0:00 sleeping less than seven hours a night is now a stronger predictor of your lifespan than your diet or your exercise routine that's the finding from a massive new us study and it lands just a week after we discussed the latest on sleep obesity and cancer in episode 20 this week sleep isn't just one of the pillars of0:22 health it is the foundation here's what else moved the active ingredient in ozempic and wegovy semaglutide just extended lifespan and improved memory muscle function and biological aging markers in older mice the nih study suggests these glp-one drugs might engage aging pathways directly not just through weight loss we'll return to this in cancer care a new phase three0:50 trial called terzo is now testing an oral drug duvelisib for patients with a rare and aggressive lymphoma that has failed other treatments it's a head to head test against standard chemotherapy and finally a new review confirms what you're probably seeing in your own life the diagnosis of obstructive sleep apnea is moving out of the lab and into1:12 your home wearable devices are being used to clear the massive diagnostic backlogs that built up during the pandemic making screening more accessible than ever so let's go back to sleep because two studies this week have fundamentally changed the conversation first the big one from oregon health and science university researchers analyzed cdc data from across the entire country1:35 and the link between getting less than seven hours of sleep and a shorter life was undeniable the lead researcher doctor matthew mchill said he was personally startled by the strength of the connection stronger than diet stronger than exercise this isn't about feeling groggy this is about mortality now this is an observational study it shows a powerful correlation1:56 not necessarily causation but it's a signal so strong you can't ignore it it tells you where to look next and that brings us to the second study this one from ucla this is the actionable part researchers took a group of older adults with insomnia and treated them with cognitive behavioral therapy or cbti it's a non drug approach2:18 it's about retraining your brain and your habits around sleep the result it worked insomnia remission rates were nearly three times higher than with just sleep education but here's the turn they also measured the participants biological age using something called an epigenetic clock think of it as a measure of your body's wear and tear at a cellular level2:41 and the group that received cbti didn't just sleep better2:47 their biological aging actually slowed let that sink in a behavioral therapy for sleep reversed a key marker of aging the lead author doctor judith carroll put it perfectly we treat insomnia like a quality of life issue these findings suggest it's a modifiable risk factor for how the body ages so what does this all add up to for3:15 years the advice has been simple sleep more but it was always a soft recommendation easily pushed aside by work by family by life this week that changes one study hands you a stark warning about the life and death stakes of sleep duration and the other hands you a powerful proven non drug tool that not only fixes the3:39 problem but makes your body biologically younger this isn't just about feeling rested it's about taking direct control over your own longevity this week sets up a new reality the biggest levers for your health might not be the ones you expect we see a hint of it in the ozempic mouse study the idea that a drug could target4:01 aging itself not just one disease but the real headline is that you don't have to wait for a miracle drug the tool is already here it's a change in behavior a decision to prioritize sleep not as a luxury but as a vital sign the question was never just how to live longer it was how to live better4:22 longer this week the answer isn't a prescription it's a decision
