Objective: This preliminary study examined whether sleepwear affected sleep parameters using nocturnal polysomnography (nPSG) and self-reported questionnaire in healthy adults.
Methods: Fourteen participants were recruited (nine females and five males; mean age, 29.43±8.58 years). nPSG was conducted for three consecutive nights, including the adaptation night, and self-reported questionnaires about sleepwear and sleep parameters were completed. On the second and third nights after the adaption night, participants were randomly assigned to a group wearing the DPV576 experimental sleepwear (ES) on the first night with the control sleepwear (CS) worn the following night, or a group wearing the two types of sleepwear in the reverse order. The objective and subjective sleep parameters for each night were compared using the paired t-test.
Results: Objective sleep variables were not significantly different between the two types of sleepwear. However, total sleep time (TST) on nPSG tended to be higher when participants wore the ES than the CS (p=0.06) in the results of nine who reported relatively high sleep quality (Pittsburgh Sleep Quality Index <5). When wearing the ES all participants reported more frequent dream (p=0.03), and less discomfort caused by sleepwear while lying down and moving in bed (i.e., tossing and turning), than the CS (p=0.04).
Conclusion: These results suggest that sleepwear type might affect objective sleep parameters (e.g., TST on nPSG) and be associated with changes in subjective sleep measures, such as the frequency of dreams and the discomfort caused by tossing and turning.
