Effect of Quilt Materials on Sleep Quality and Thermal Comfort for Young People in East China

摘要

This study investigated sleep quality and thermal comfort under different quilt materials (white duck down, white goose down and cotton) in non-heating bedroom for young people in East China via subjective and physiological methods. Thermal comfort and sleep quality were evaluated before and after sleep. Electroencephalograms were also obtained to deter-mine the sleep stage. Both results show that quilt materials have a significant effect on sleep quality. The subjective results show that goose down quilt is evaluated the most comfortable in overall sleep comfort and sleep thermal sensation. The objective results show that the slow-wave sleep is the longest under goose down condition. Subjective and objective results are consistent, indicating that sleep quality is the highest when candidates were subjected to goose down material. Meanwhile, the study finds that lighter quilts would have a higher degree of satisfactions, indicating that young people in East China may have a preference for light quilt.
