“…Although the temperature of the sleep environment does not influence the proportion of time in each sleep stage, women were unable to attain a sound sleep at low temperature (Rohles and Munson 1981). Cold ambient temperatures are generally more disruptive to sleep than warm temperatures (Haskell et al 1981).…”

Six models for determining air temperatures for thermal comfort of people using sleeping bags were reviewed. These models were based on distinctive metabolic rates and mean skin temperatures. All model predictions of air temperatures are low when the insulation values of the sleeping bag are high. Nevertheless, prediction variations are greatest for the sleeping bags with high insulation values, and there is a high risk of hypothermia if an inappropriate sleeping bag is chosen for the intended conditions of use. There is, therefore, a pressing need to validate the models by wear trial and determine which one best reflects ordinary consumer needs.

“…The results from these studies have shown that the neutral temperature for sleeping with shorts on only was between 28°C and 32°C 18‐20 . When adding duvets with different insulation levels, the neutral temperature could be reduced to approximately 21.2°C –30.9°C 21‐24 . In two studies carried out by Lan et al, 21,25 the most comfortable temperatures in winter and summer were suggested to be 23°C and 26°C, respectively.…”

Sleep accounts for one-third of people's lives and is used to help overcome fatigue, recover energy to protect from brain damage, 1 and maintain physical and mental health. 2 Sleep disorders, however, are not uncommon among the general public, and approximately one-third of adults suffer from relevant issues. 3 Poor sleep quality can damage the physical and mental health of people, especially adolescents 4 and the elderly. 5,6 For sleep quality, there are many influencing factors, such as acoustic environment, visual environment, thermal environment, and human psychological stress, with thermal environment have been suggested as a major factor. 7 A comfortable indoor thermal environment is even more important for sleeping than for awake times due to a reduced metabolic rate, which regulates the core temperature of the human body, and limited adaptive abilities. 8 A well-maintained indoor thermal environment during the sleeping period contributes to a reduced number of wake-ups caused by thermal discomfort, hence improving sleep quality. 9,10 To

“…Temperature and humidity in a room have big impacts on one's sleep, learning, subjective well-being and comfort degree, etc. [4][5][6], and their abnormal values can be life-threatening [7]. Besides, environmental temperature and humidity are the key elements to affect production efficiency and product quality in many industrial activities such as manufacturing, processing and production of biological product [8,9], food [10,11], tobacco [12,13] and so on.…”

Aim at an air-handling unit (AHU), this article describes a direct design scheme for humidity and temperature tracking control. The nonlinear dynamic model of the AHU is treated directly by backstepping strategy, which can reserve the modeling qualifications and make better use of known information than proportion integration differentiation (PID) and other non-model-based schemes. Simultaneously, the linearization technique is not adopted, so that the model structure is not changed, which can retain the original system model restrictions to variables and does not lose useful conditions about the system model. These two points ensure the developed controller to achieve higher accuracy and better tracking performance, which is verified by stability analysis and comparisons of simulation results.
