本研究以青年人冬季在无暖气卧室中的睡眠质量和热舒适性为指标，对3种不同棉被（白色鸭绒被、白色鹅绒被和纯棉被）的性能进行了评价。在睡眠前后主观评价热舒适性和睡眠质量。脑电图（EEG），皮肤温度和床的气候测量整个通宵睡眠。主观和生理结果均表明，被子材料对睡眠质量和热舒适性有显著影响。在睡眠舒适度和睡眠热感觉方面，鹅绒被评价为最舒适。使用鹅绒被时，由EEG信号计算的慢波睡眠持续时间更长，皮肤温度和床温更高。结果还表明，皮肤温度存在性别差异。与男性相比，女性的平均皮肤温度（MST）较高，足部温度较低，提示女性在冬季睡眠时应注意保持肢体温暖。研究结果表明，羽绒被对睡眠质量和热舒适性的影响最大，而棉被的影响最小。羽绒被可以保证华东地区冬季不供暖的卧室有一个舒适的床气候。结果还表明，较轻的被子会有较高的满意度，这表明中国东部地区的年轻人可能有一个偏好轻的被子。
This study evaluated the performance of three different quilts (white duck down quilt, white goose down quilt and cotton quilt) based on sleep quality and thermal comfort of young people in non-heating bedroom in winter. Thermal comfort and sleep quality were subjectively evaluated before and after sleep. Electroencephalograms (EEG), skin temperatures and bed climate were measured throughout the all-night sleep. Both subjective and physiological results showed that quilt materials had a significant effect on sleep quality and thermal comfort. The goose down quilt was evaluated the most comfortable in overall sleep comfort and sleep thermal sensation. The duration of slow wave sleep as calculated by EEG signal was longer, the skin temperatures and bed climate were higher when the goose down quilt was used. The results also show that there are gender differences in skin temperatures. Compared with males, the mean skin temperature (MST) of females was higher, while their foot temperature was significantly lower, which suggest that for females more attention should be paid to maintain warmth of extremity during sleep in winter. Our results suggest that sleep quality and thermal comfort is the most desirable when using goose down quilt and undesirable when using cotton quilt. Duvet could guarantee a comfortable bed climate in non-heating bedroom in winter of East China. Results also showed that lighter quilts would have a higher degree of satisfactions, indicating that young people in East China may have a preference for light quilt.
