Estimating thermal resistance of dry infant bedding — Part 1: a theoretical mathematical model

The purpose of this work was to develop a model for estimating “dry” and “wet” thermal resistance of bedding during use. The model takes into account proportions of the body covered by different bedding arrangements, and the effects of an infants sleep position and method of tucking on thickness, thermal resistance and heat loss. Predictions of thermal resistance using various published formulae are compared with those from this study.
