Every night, your brain does something amazing while you sleep. ✨🎤It cleans itself, stores new memories, and prepares for the next day. ✨🎤Scientists compare this process to a city cleaning its streets at night. ✨🎤

When you study something new, the information is fragile at first. ✨🎤During deep sleep, your brain repeats the day's lessons and moves them into long-term memory. ✨🎤This is why students who sleep well before an exam often get better results than students who study all night. ✨🎤

Teenagers need about nine hours of sleep, but most get much less. ✨🎤Phones and bright screens trick the brain into thinking it is still daytime. ✨🎤Experts suggest putting your phone away one hour before bed. ✨🎤Good sleep is not lost time — it is the secret tool of every successful student. ✨🎤
