Abstract
We examined the effects of a high-rebound bedding use on improving objective and subjective sleep quality and mood states after waking in healthy young males. Ten healthy young males voluntarily participated in this study. The participants underwent two experiments under different mattress conditions, high-rebound and low-rebound bedding (mattress and pillow) conditions. The electroencephalogram was continuously measured from the time the participants retired to bed until awakening, and subjective sleep quality and mood state were evaluated after waking the following morning. Sleep latency and total awakening after sleep onset were significantly lower and sleep efficiency, total delta power during non-REM sleep, and total delta power during the first cycle were significantly higher in the high-rebound bedding than in the low-rebound bedding (p < 0.05). The OSA-MA components of “sleepiness on rising” and “initiation and maintenance of sleep” were significantly higher in the high-rebound bedding compared with the low-rebound bedding (p < 0.05). Furthermore, the moods “fatigue–inertia” and total mood disturbance scores after waking were significantly lower, while the components “vigor–activity” and “friendliness” were significantly higher in the high-rebound bedding compared with the low-rebound bedding (p < 0.05). This study is an exploratory and hypothesis-generating preliminary study limited to healthy young males, and it only shows that the specific high-rebound bedding used in this study exhibited more favorable results than a specific control bedding.
