なぜ 26 分の昼寝が人生を変えるのか【神経科学×睡眠科学】

Have you ever heard of the "26-minute nap"? A 1995 NASA experiment with long-haul pilots confirmed that a mere 26-minute nap improved attention by 54% and performance by 34%. Sleep science suggests the optimal nap window is 20-30 minutes. Beyond 30 minutes, "sleep inertia" can occur, sometimes leading to counterproductive effects. This video gently explains everything from the neuroscientific mechanisms behind afternoon drowsiness to the effects of napping on cognitive function, memory, and emotions, and even the science behind "Coffee Naps"—combining caffeine and napping. SUIMIENCE is a channel that explains the mysteries of sleep, the brain, and memory before bedtime, based on papers from journals such as Nature, Cell, and Science.
