Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Sleep deficiency is a hidden cost of our 24-7 society, with 70% of Americans admitting that they routinely obtain insufficient sleep, 30% of US workers report sleeping less than 6 hours per night, and it is estimated that 50-70 million individuals have a sleep disorder. Undiagnosed and untreated sleep disorders are associated with poor health outcomes for the individual and generate substantial costs for the employer. Diminished alertness resulting from sleep deficiency or undiagnosed and untreated sleep disorders contributes to absenteeism, presenteeism (diminished work performance at work), health care expenditure, occupational injuries, workplace accidents, and commute-related motor vehicle crashes; all of which result in substantial direct and indirect costs. The investigators have shown that adverse impacts on employees and employers can be mitigated through a sleep health education and sleep disorder screening program which have been implemented in a variety of industries. Further, smartphone apps are becoming popular. Dayzz has created a personalized sleep training app that evaluates sleep issues and offers a holistic sleep improvement solution. It is unique in that the sleep app uses evidence-based, big-data-based algorithms to provide personalized sleep training plans. The sleep solutions are tailored to the individual user and leverages unique motivational strategies and continuous supportive messaging. The investigators hypothesize that the Dayzz app, offering a personalized, scientifically based sleep training plan, might further promote improved health, safety and well-being. This clinical trial will implement the sleep health education and sleep disorders screening program in combination with the Dayzz app.
