You don’t just learn when you’re awake. Your brain keeps studying while you sleep — if you let it.
During sleep, your brain replays, reorganizes, and stores everything you studied. It's like overnight revision — without effort.
REM sleep connects scattered ideas. Deep sleep cements facts. You need both for full learning. Sleep is where fragments become understanding.
When you skip sleep, your recall drops. You’ll read twice, forget faster, and blame yourself — but it’s just sleep deprivation speaking.
