Q4: 'The Science of Sleep' - Read the passage aloud

Sleep is essential for health, yet many people don’t get enough. During sleep, the body repairs itself and the brain processes memories. Lack of sleep can lead to poor concentration, mood swings, and even illness. Teenagers need around nine hours of sleep each night, but homework, screens, and stress often reduce that time. Scientists recommend creating a bedtime routine, avoiding caffeine, and limiting screen time before bed. Sleep isn’t just rest—it’s a vital part of learning and growth. Understanding sleep helps us make better choices and improve our wellbeing.
