People with sleep disorders could certainly use something like this to establish a history of their sleep cycles over a few weeks, enabling them to perhaps correlate certain weekly or monthly events that, as part of their lifestyle, may be negatively or positively affecting their sleepcycles and thereby their very health. Perhaps an exploration of these events and the behavior leading up to them, with a doctor, may be more effective, in terms of cost and time, than a one-time sleep study at a specialist center.
