Abstract
We evaluated the effects of eye-masks containing heat- and steam-generating (HSG) sheets application to the eyes during sleep on sleep quality. The former 3 days were used as a control period (control condition). On the latter 3 days, the subjects used eye-masks containing HSG sheets during sleep (HSG sheets condition). An actigraph was worn on the non-dominant wrist during sleep under each condition. As a result, the sleep latency slightly decreased under HSG sheets condition than under control condition, and the total awake period during sleep in the former half of sleep significantly decreased under HSG sheets condition. In addition, the self-evaluated sleep quality on waking up significantly improved. The application of HSG sheets at bedtime was useful for inducing sleep.
