Background and Objective Patients with position-dependent obstructive sleep apnea have a > 2-fold higher apnea-hypopnea index when sleeping in a supine position compared with a non-supine position. We investigated the effect of body pillow use on sleeping body position and sleep architecture in healthy young adults. Methods In experiment 1, we evaluated the body pressure distribution with or without body pillow use in 8 healthy young adults [age, 36.5 ± 13.0 years; body mass index (BMI); 20.6 ± 1.2 kg/m2]. In experiment 2, we performed a randomized-crossover intervention study to evaluate the effects of body pillow use on sleeping position and sleep architecture in 10 healthy young adults (age, 24.3 ± 7.8 years; BMI, 21.4 ± 1.7 kg/m2). Sleep architecture was characterized by polysomnography, and body positions were monitored using a sensor. Subjective sleep quality was evaluated with the Oguri-Shirakawa-Azumi sleep inventory, middle age and aged version. Results In experiment 1, body pillow use significantly reduced mean body pressure on the shoulder, hip, and whole body. In experiment 2, mean time spent in the supine, lateral, and prone body positions did not differ significantly between the 2 trials. Body pillow use, however, significantly extended the sustained time spent in the lateral body position compared with the control trial. Subjective sleep quality and sleep architecture did not differ significantly between the 2 trials, but body pillow use decreased the number of short (30 s) slow-wave sleep episodes. Conclusions Sleeping with a body pillow effectively extends sustained time in a lateral sleeping position and prevents segmentation of slow-wave sleep episodes.

Background and Objective This study evaluated the effects of a mattress with better body pressure dispersal in comparison to a control mattress on sleep quality. Methods In this randomized crossover study, 10 healthy young men slept in an experimental sleep room on either a functional mattress made from polyurethane, with a special four-layer three-dimensional structure, or a control mattress made from solid polyester wadding, which is a mattress commercially available in Japan. Polysomnography recordings were used to characterize sleep architecture, and the length of slow wave sleep (SWS) episodes and delta power density were calculated from the electroencephalography data and subjective sleep quality was evaluated by questionnaire they answered after waking. Results There were no significant differences in sleep latency, the total duration of each sleep stages, total sleep time, or sleep efficiency. Although the difference was subtle, delta power density significantly increased with the functional mattress. There was no difference in the total duration of SWS, but there were significantly fewer SWS episodes with the functional mattress (10.3 ± 1.8) than with the control mattress (16.9 ± 1.2) and longer SWS episode duration (10.9 ± 1.7 min) with the functional mattress than with the control mattress (5.6 ± 0.5 min). Conclusions It was suggested that the functional mattress lengthened SWS episode duration, and its fragmentation was effective in evaluating the sleep quality of healthy young individuals.
