Poor sleep damages your heart, blood pressure, metabolism and long-term health far more than most people realise. In this video I explain what poor sleep and irregular sleep patterns actually do inside the body, and why they increase the risk of heart disease, stroke, inflammation, insulin resistance and early death over time. As an Emergency Medicine doctor who spent years working permanent night shifts, this is one of the health topics I care about most personally. In this video I break down the major research on sleep duration and sleep regularity, including the huge meta-analyses and UK Biobank studies showing how both short sleep and irregular sleep schedules independently damage cardiovascular health. We also explore: -Why your blood pressure is supposed to fall at night -What happens when your body never properly “switches off” -The role of cortisol and chronic stress hormones -Why sleep deprivation increases inflammation -The connection between poor sleep and heart attacks -Why shift work feels so damaging -The science of sleep regularity -The U-shaped relationship between sleep duration and mortality -The sleep habits that actually improve long-term health TIMESTAMPS: 00:00 Why poor sleep quietly damages the heart 01:21 The two ways sleep goes wrong 05:15 Blood pressure that never switches off 07:22 A body stuck in alarm mode 09:26 A slow internal fire 11:13 What night shifts did to me 13:43 What this means for you REFERENCES: Sleep duration and risk of cardio-cerebrovascular disease: A dose-response meta-analysis of cohort studies comprising 3.8 million participants https://pubmed.ncbi.nlm.nih.gov/36237900/ Sleep regularity and major adverse cardiovascular events: a device-based prospective study in 72 269 UK adults https://pubmed.ncbi.nlm.nih.gov/39603689/ Impact of sleep debt on metabolic and endocrine function https://pubmed.ncbi.nlm.nih.gov/10543671/ Sleep Disturbance, Sleep Duration, and Inflammation: A Systematic Review and Meta-Analysis of Cohort Studies and Experimental Sleep Deprivation https://pubmed.ncbi.nlm.nih.gov/26140821/ Short Sleep Duration Is Associated with Reduced Leptin, Elevated Ghrelin, and Increased Body Mass Index https://pubmed.ncbi.nlm.nih.gov/15602591/ Sleep duration predicts cardiovascular outcomes: a systematic review and meta-analysis of prospective studies https://pubmed.ncbi.nlm.nih.gov/21300732/ Sleep regularity is a stronger predictor of mortality risk than sleep duration: A prospective cohort study https://pubmed.ncbi.nlm.nih.gov/37738616/ Short Sleep Duration as a Risk Factor for Hypertension: Analyses of the First National Health and Nutrition Examination Survey https://pubmed.ncbi.nlm.nih.gov/16585410/ Quantity and quality of sleep and incidence of type 2 diabetes: a systematic review and meta-analysis https://pubmed.ncbi.nlm.nih.gov/19910503/ Brief communication: Sleep curtailment in healthy young men is associated with decreased leptin levels, elevated ghrelin levels, and increased hunger and appetite https://pubmed.ncbi.nlm.nih.gov/15583226/ Shift work and vascular events: systematic review and meta-analysis https://pubmed.ncbi.nlm.nih.gov/22835925/ If you enjoy these evidence-based videos on longevity, metabolic health, heart disease prevention, sleep, lifestyle medicine and healthy ageing, please consider subscribing. #sleep #hearthealth #longevity #bloodpressure #sleepscience #dralex #doctoralex
