Sleep is important for maintaining good health: Our bodies and minds are repaired and restored during sleep. Without adequate sleep, and without good quality sleep, our physical well-being and mental health suffer. Inadequate sleep can accelerate development and progression of chronic disease; can be a predictor and/or a symptom of chronic disease; and is common in virtually every chronic disease.

Improving sleep and the quality of sleep, and diagnosing the root cause of sleep disorders earlier in the course of chronic disease, could aid in delaying chronic disease, benefit patients, and lead to a greater understanding of the link between chronic diseases.
