How many hours of sleep is healthy?

For most people, getting between 7 and 9 hours of sleep each night is best for their health. But everyone's sleep needs are different because of things like age, genetics, habits, and health in general. Some people may be fine after less than 7 hours of sleep, while others may need more than 9 hours to feel fully relaxed.

Getting enough sleep is important for your health, your brain, your happiness, and your defense system. Getting enough sleep every night can also lower your chance of getting long-term diseases like diabetes, obesity, and heart disease. Setting a normal sleep routine, making your bedroom comfy, and following good sleep hygiene habits are all important ways to make sure you get the rest you need for good health and functioning.
