One 20-minute habit before sleep doubles your next-day focus — and it has nothing to do with melatonin or blue light glasses.
The science: during the first 90 minutes of sleep, your hippocampus replays everything you learned that day — transferring it to long-term memory. A 2019 Harvard study found that what you do in the 20 minutes before sleep determines how much of the day's learning your brain consolidates. The window is real. And most people waste it on Netflix.
