The Explanation
Sleep isn't just rest – it's when your brain does essential maintenance. During sleep, your brain consolidates memories, clears toxins, and prepares for the next day.
Teens need 8-10 hours of sleep, but most get far less. Your natural sleep rhythm shifts during adolescence, making you want to stay up later and sleep in longer.
Chronic sleep deprivation can impair learning, mood, and even physical health. Prioritizing sleep is one of the best things you can do for your brain.
