Sleep is an important part of our health and wellness, and a major factor in preventative health care. Maintaining a consistent schedule for when you go to bed and wake up trains your body, and results in a more restful, fulfilling night’s sleep. Adults should get 7 to 8 hours of sleep; teenagers and children need more sleep as part of normal growth and development. Eating habits, exercise, and the quality of your sleep are interconnected; see “Eating habits” and “Exercise” below. Studies show that eating just before sleeping prevents restful sleep since your digestive system continues to work and process food.
