“…In this study in winter, the tendencies were inhibited during sleep‐onset period. Sassa et al reported that the skin temperatures of upper and lower limbs were lower in winter than those in summer even if exposed to the same hot conditions for 3 h 6 . The results suggest that the skin temperature of the foot at night‐sleep was also influenced by seasonal accommodations.…”

To clarify the thermally comfortable environment for satisfied sleep, we investigated the relationship between skin temperatures and sleep stages during night-sleep in winter, summer and autumn. Four healthy young females served as the subjects. The experiments were performed in a climate chamber under three conditions: at 13°C-RH70% with futon and blanket in winter, at 20-18°C-RH60% with futon and towelket in autumn and at 29°C-RH70% with towelket in summer. The subjects' skin temperature on the sole was lower until about 4 hours after lights off in winter than in autumn and summer, and the percentage of st.2 was lower and st.4 was higher in winter than in autumn and summer, although the bed climate both in winter and autumn was much the same.

“…In the spring, the distribution of globe temperatures was 18.0e25.6 C, a wider range than that of the indoor temperature, Globe temperature (Testo 480) 0 to þ120 C 0.1 C ±0.5 C (0 to 50 C) ±1 C (50 to 120 C) Airflow (Hario WGT- 10) 0.05e20 m/s 0.01 m/s ±0.03 m/s which means that the variation in globe temperature is large during the transition from winter to spring. The air current was 0.093 m/s in spring, 0.118 m/s in summer, 0.064 m/s in autumn, and 0.054 m/s in winter.…”

“…It is characterized by the presentation of subjective evaluations, which are affected not only by personal factors but also by psychological factors, the time of day, or by physical conditions [8]. In a study conducted by Sassa et al, when individuals were allowed to adjust indoor temperatures to the temperatures felt comfortable by them in an artificial climate room where temperatures were not indicated, a large temperature difference of 7.2 C was seen among 29 test subjects [9,10]. Thus, the definition of "thermal comfort" differs depending on behavior patterns, psychological conditions, climate, race, age, gender, and the degree of fatigue that subjects experience [8,11].…”

“…When experimental subjects were allowed to control indoor temperatures, the comfort temperatures of the subjects could vary as widely as 7.2°C. The researchers argued that psychological factors, or users’ control over the environment, were important [15,16]. As stated, the comfort range of indoor environment could be influenced by various factors including physical conditions, and thus it is necessary to consider wide-ranging aspects to improve the comfort level of indoor environments.…”

A comfortable indoor environment is an essential condition for establishing a healthy housing environment. The indoor comfort is influenced by not only architectural conditions, but also residents' psychological adaptation and behavioural adjustments. Moreover, specific information about adjusting behaviours, such as opening windows, closing blinds and adjusting clothing, is important to enhance indoor comfort effectively and reduce energy consumption at home.The purpose of this study is to explore residents' evaluation and adjusting behaviour related to the indoor comfort of apartments in Korea. This study collected residents' evaluations of thermo, sound, light and air conditions through surveys on their satisfaction, and the study identified factors affecting residents' evaluations. In addition, this study investigated adjusting behaviours that would improve levels of indoor comfort based on the unique attributes of apartments and residents' living culture, and it analysed the relationship between such behaviour and their satisfaction. The questionnaire survey was collected from apartment residents. Frequency analyses, t-test and multiple linear regression analysis were employed.The results of this study would contribute to developing plans and management guidelines for enhancing indoor comfort and satisfaction as specific and practical data.
