Abstract

:and easy movability, and so on, are considered to be some of major conditions that affect the comfortable sleep. Con-sidering those factors together, the thermal properties, height, shape and feeling of touch, etc, of pillow must be takeninto account. Though studies have been conducted to figure out the physical properties of mattress or pillows from theperspective of factors related to the environment of sleep, they are not enough to be used as an index to evaluate thequalitative aspect of sleep. This study tries to consider the effect of pillow filling materials on the comfortable sleep, forwhich EG, ECG, EOG, EMG, RT, etc, are to be measured in an attempt to provide the basic data required in proposingthe condition that may lead to a sound and comfortable sleep. Three types of pillows that are sold in the market wereused for this research in order to evaluate the quality of sleep depending on the filling materials of pillow. All data werebest comfort as the pillow A turned out to have the shortest sleeping latency(SL) from the perspective of comfort. Thepillow B which used the polyethylene is deemed to be suitable for fatigue relieving purpose as it turned out to have thehighest slow wave sleep(SWS), but no statistically significant difference was validated. Moreover, the pillow C which usedthe natural wool was found to have the narowest contacting area of the pillow and head and provide a great warm heatcomfort that may led to a sound sleep because the temperature below the pillow took the longest time to rise.
