Summary

While you sleep, your body is hard at work. It restores hormonal balance, repairs itself, and keeps the circulatory and immune systems functioning properly. Your brain forms and stores memories.

Getting adequate sleep—seven to nine hours a night—keeps your heart healthy, reduces stress, and helps keep blood sugar consistent. It also reduces stress, prevents inflammation, helps control weight, and is important for memory formation and clear thinking.

Quality sleep allows you to be energetic and alert. It allows you to exercise, work, learn, socialize, and do all the things you enjoy.
