Sweet dreams: review of a sleep tracking framework

Sleep disorders result in sleep deficiency and are becoming epidemic issues among both young children and adults. A 2016 CDC study by the U.S. Centers for Disease Control and Prevention1 revealed that more than a third of American adults and one out of four young American children lack sufficient sleep on a regular basis. Another study conducted by the National Institute of Neurological Disorders and Stroke2 pointed out that every year, the US alone has over 40 million people suffering from chronic sleep disorders. Lack of sleep3 can cause detrimental health effects, such as increased probability for diabetes, neurological disorders, and heart disease as well as a weakened immune system. There is little doubt that sleep is essential for health, growth, normal physiological functions, and learning abilities in children.
