Abstract

Objective: The aim of this study was to explore the effect of fabric material worn during nocturnal sleep on stratum corneum water content (SCWC) under mild cold conditions.
Method: A controlled cross‐over study has been designed to investigate systematically the effects of two kinds of pajama materials, cotton and polyester, on SCWC. Factors such as pajama fabric material, subjective perception and sleep quality were examined. Hierarchical linear regression was applied to assess the association between the factors and SCWC.
Results: Fabric material and subjective perception of coldness significantly predicted SCWC in the wear trial. Polyester fabric had a negative effect on SCWC compared with cotton, and subjective perception of coldness also had a negative effect on SCWC.
Conclusion: The mechanisms by which pajama fabrics affect the SCWC could be due to the different thermal/hygroscopicity properties of the polyester and cotton fabric and the integral involvement of physiological and neurophysiological processes. Copyright © 2007 The Authors.
