Abstract

<p>One-third of the Japanese is dissatisfied with the quality of sleep. One of the factors that hinder the quality of sleep depth is the influence of temperature and humidity in-bed, which rises due to body temperature during bedtime. The purpose of this study was to investigate indoor temperature/humidity that provides a comfortable in-bed environment and was to investigate sleep quality between regular polyester （RP） and weaken acid polyester （WP） of sleepwear. A pilot study was conducted in 10 healthy volunteers who recruited students at the Matsumoto University. Temperature/humidity in-bed was measured using portable temperature and humidity data logger. Three-room temperature （10, 20, 30℃） and two fabric （feather, cotton） were conducted.</p><p>Another study was conducted in 3 patients who complained of skin itching. Participants with a finger ring sleep monitor put on RP or WP during in bed. Sleep quality was assessed using the OSA sleep inventory MA version （OSA-MA）， the Japanese version of the Athens Insomnia Scale （AIS）， the itch VAS score during nighttime.</p><p>There was no difference in the time to reach 31℃ in the bed among three room temperature. At the wrists and ankles of more than 50% of participants, the temperature in the bed did not exceed 31℃．Relative humidity showed less than 45% after 30 min in the participants. Dryness condition considered inducible itching to human skin.</p><p>There was no difference between RP and WP of sleepwear in OSA-MA, AIS, VAS and sleep depth, however, individual cases seemed to be improved in the WP.</p><p>Thus, WP of sleepwear might improve sleep quality during bedtime.</p>
