It’s important to get enough sleep. Sleep helps keep your mind and body healthy. How much sleep do I need? Most adults need 7 to 8 hours of good quality sleep on a regular schedule each night. Make changes to your routine if you can’t find enough time to sleep. Getting enough sleep isn’t only about total hours of sleep. It’s also important to get good quality sleep on a regular schedule so you feel rested when you wake up. If you often have trouble sleeping – or if you often still feel tired after sleeping – talk with your doctor. How much sleep do children need? Kids need even more sleep than adults. Teens need 8 to 10 hours of sleep each night. School-aged children need 9 to 12 hours of sleep each night. Preschoolers need to sleep between 10 and 13 hours a day (including naps). Toddlers need to sleep between 11 and 14 hours a day (including naps). Babies need to sleep between 12 and 16 hours a day (including naps).
