Psychology of Sleep: How To Sleep Less Hours And Wake Up Fresh Dự phòng: Psychology of Sleep

You can spend nine hours in bed and walk away with barely six hours of real sleep. So you go to bed earlier, sleep in on weekends, and still wake up exhausted. Psychology says the problem usually isn't how much you sleep. It's how much time you waste in bed around it. In this video, we look at the psychology of sleep: why extra time in bed can make you more tired, how Arthur Spielman's sleep restriction therapy works, Alexander Borbély's two-process model of sleep, and the four quiet mistakes that keep mornings foggy — the extra hour, the weekend reset, trying to sleep, and the wrong exit. Then we go through four science-based ways to trim the wasted hours, protect the seven hours your body truly needs, and finally wake up fresh. Not sleeping less. Wasting less. ⏱️ CHAPTERS 0:00 Nine hours in bed, still exhausted 0:56 It's not a willpower problem 1:21 Welcome to Quietly Human 1:37 The treatment that gives you less time in bed 2:37 The two systems that control your sleep 3:15 Why extra time in bed backfires 3:55 How the crisis plan never switched off 5:12 Mistake 1: The extra hour 6:07 Mistake 2: The weekend reset 7:27 Mistake 3: Trying to sleep 8:30 Mistake 4: The wrong exit 9:19 The sleep paradox 9:47 Can you really sleep less?
