The public health significance of sleep disorders is substantial, accounting for hundreds of billions of
dollars each year in direct medical costs. Sleep disorders increase risk of neurocognitive and
cardiovascular morbidity and premature death. They also impair daily performance, increase pain sensitivity
and decrease quality of life. Much of this disease burden could be averted with presently available treatment. Yet the majority of sleep disorders remain undiagnosed. This feasibility study will test the validity of the Beddit sleep monitor, FitBit wrist-band, and ResMed S+ for estimating sleep stage and duration, and wake after sleep onset, by comparison with type 1 polysomnography (PSG), the current gold standard for sleep disorder diagnosis.
