There is no one right sleep pattern for everyone, as people vary in terms of the amount of sleep they need and the time of day they are most alert. However, most adults need between 7 and 8 hours of sleep per night to feel their best. The National Sleep Foundation recommends going to bed and waking up at the same time each day to establish a normal sleep pattern. It's also important to avoid caffeine and alcohol before bed, and to keep electronic devices out of the bedroom.
