Martin explains why consistent sleep timing is linked to all-cause mortality, and why your body craves rhythm across sleep, meals, caffeine, training, travel, and daily life.We also talk about chronotypes, deep sleep, REM sleep, wearables, melatonin, alcohol, late meals, cannabis sleep gummies, naps, jet lag, and sleeping with a partner.This is a practical conversation about building a sleep rhythm that works in real life — without turning sleep into one more thing to obsess over.In this episode:Why sleep gets harder after 50Why older adults do not necessarily need less sleepThe sleep habit linked to all-cause mortalityWhy regularity may matter more than chasing 8 hoursWhat wearables can and cannot tell youCaffeine, alcohol, late meals, and 3 a.m. wakeupsMelatonin, cannabis gummies, naps, and jet lagSleeping with a partner, intimacy, and “sleep divorce”How to improve sleep without becoming obsessiveSubscribe and share this episode with someone who keeps waking up tired.Timeline: Support cellular renewal and mitochondrial function with Mitopure, featuring Urolithin A.
