“…Introduction The influence of a person's immediate surroundings and physical environment (such as bed and bedroom condition) on sleep has gained interest. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] This study aimed at identifying a standard methodology or guideline to assess the thermal comfort of sleeping people in bedrooms. The literature suggests there are various methods, approaches, tools, and metric to measure and quantify sleep quality and thermal comfort in isolation.…”

A comfortable mattress can create a good sleep environment, but the thermal behaviour of the interaction between the human body and mattress materials is still not well understood. The effect of mattress materials on human–mattress interface temperature and human thermal state was evaluated by subjective questionnaire and measurements to detemine the human–mattress interface temperatures of the whole body and various locations of the body (WTH-M and ETH-M). The woollen fabric and polymeric foam of mattresses were evaluated as optimal cushion materials; these were indicated by measurements at 15.5 and 20°C, due to the higher WTH-M and ETH-M. Moreover, the interface temperatures measured at the back, buttock and thigh were higher with most materials than at other parts of the body, indicating a lower temperature response at the body extremities due to the body–mattress interface. Under the cold climate, people would prefer warm thermal sensation rather than the neutral thermal feeling. There should be more consideration on the thermal insulation of the extremities such as the feet. The human thermal response was not only affected by mattress materials, but also by body parts and indoor air temperatures. These findings are important to understand the heat transfer and human thermal comfort requirements, providing a comfortable thermal environment to ensure sleep quality.

“…Many studies have focused on the thermal comfort of bedding, and some physiological experiments and manikin tests were carried out to evaluate human thermal responses. The impacts of bedding materials, bedding insulation, indoor temperature and other factors on sleep quality and thermal comfort have been investigated ( € Ozer et al, 2020;Lu et al, 2021;Zhang et al, 2020;Shen et al, 2015). Most of them were conducted for adults, but the studies on infant bedding are limited.…”

PurposeThe purpose of this study is to determine the temperature ratings of infant bedding.Design/methodology/approachMathematical models were developed for predicting temperature ratings of infant bedding for all age groups based on the thermal balance equation. These models were validated by the published physiological data and the baby manikin tests. The air temperature was compared with the predicted temperature rating, and the skin temperature of infant or baby manikin was used to explain the validation results.FindingsThe models had higher prediction accuracy, especially for the infant bedding with uniformly distributed thermal insulation. The results showed that an increase of 1 clo in thermal insulation caused a decrease of 4.2–6.0 °C in temperature rating. The slope of the model reduced with the increasing month-age, indicating that an older infant had a lower temperature rating than a younger infant.Practical implicationsSuggestions were given for caregivers that younger infants ought to be covered with more bedding than adults; however, older infants were expected to require less bedding.Originality/valueThe outcomes provided scientific guidelines on the selection of bedding for infants at a particular room temperature to ensure the health and safety of infants.
