Most people should get between 7 and 9 hours of sleep each night. But everyone's sleep needs are different because of things like age, hormones, and health in general. Infants and young children need more sleep, usually between 10 and 14 hours a night. Teenagers may need between 8 and 10 hours of sleep each night to help them grow and develop. People over the age of 65 may need about 7 to 8 hours of sleep each night. It's important to put both amount and quality of sleep first when it comes to good sleep habits. Getting the required amount of sleep every night can improve your happiness, your immune system, and your general health. To make sure you feel relaxed and ready for the day, you should pay attention to your body and change the way you sleep as needed.
