The amount of sleep a person needs varies based on multiple factors. “A healthy adult usually needs around 7 to 9 hours of sleep,” the NHS advises. However, individual requirements differ depending on factors such as age, health, and personal circumstances.
Some people naturally require more sleep than others. Teenagers, children, and babies need additional rest to support their growth, with newborns sleeping anywhere from 8 to 16 hours a day.
