“…When stimuli are high, such as noisy family members, hot temperature, and loud music, adjustments may be more difficult [ 49 ]. The children's experiences of temperature when using weighted blankets could be due to sensory difficulties [ 19 ], their individual thermoregulatory capacity [ 50 ], or environmental temperature differences [ 51 , 52 ]. Comfortable bedding is critical for maintaining sleep [ 51 ], and contextual aspects such as the risk of the weighted blanket sliding off the bed and cosleeping family members were also experienced by the children in our study as influencing the use of the blankets.…”

Introduction. Sleeping difficulties are common in children with attention deficit hyperactivity disorder (ADHD). A sleep intervention with weighted blankets was designed to increase current understanding of using weighted blankets to target children’s individual needs in connection with sleep and daytime functioning. Aim. To explore how children with ADHD and sleeping difficulties experience the use of weighted blankets. Methods. An explorative qualitative design in which 26 children with ADHD and sleeping difficulties, 6–15 years old, were interviewed about a sleep intervention with weighted blankets. Four categories emerged from qualitative content analysis. Results. Children’s experiences revealed that the use of weighted blankets 1) requires a commitment, by adjusting according to needs and preferences and adapting to the environment; 2) improves emotional regulation by feeling calm and feeling safe; 3) changes sleeping patterns by creating new routines for sleep and improving sleep quality; and 4) promotes everyday participation by promoting daily function and balancing activity and sleep. Conclusions. Using weighted blankets promoted children’s management of daily life with ADHD and sleeping difficulties. Occupational therapists can improve the assessment and delivery of weighted blankets tailored to individual needs based on increased knowledge from the children themselves.

“…The lack of a comfortable thermal sleep environment affects daytime activities, impacts health, and also deteriorates the quality of life [29]. Okamoto-Mizuno and Mizuno [29] emphasized that the thermal environment is one of the most important factors affecting human sleep and found that cold exposure might have a greater impact on sleep than heat exposure. According to the ANSI/ASHRAE Standard 55 [30], temperature fluctuations of 2.2 • C or more per hour significantly contribute to thermal discomfort in indoor environments [31].…”

Post-disaster housing, constructed on a massive scale, often overlooks the indoor thermal environment, despite being a crucial design factor for residential satisfaction. This study examined the indoor thermal environment in post-Gorkha earthquake-reconstructed prototype and traditional vernacular houses in the Dolakha district of Nepal. It employed a questionnaire survey and measurement of indoor and outdoor temperature in both house types across two study locations: Panipokhari and Jillu, during the coldest winter month. Despite the indoor temperature in both house types falling below the ASHRAE comfort standard, the study found that prototype houses’ nighttime indoor temperatures were 2.1 °C lower in Panipokhari and 1 °C lower in Jillu compared to vernacular houses. This difference is attributed to the use of local building materials with low U-values, substantial thermal mass in vernacular houses, and a low window-to-wall ratio. Occupants expressed dissatisfaction with the thermal environment in prototype houses compared to vernacular ones. By incorporating climate-responsive features seen in vernacular houses, heating energy could have been reduced by approximately 21% in Panipokhari and 10% in Jillu, easing the economic burden on vulnerable households. These findings hold significance for policy-makers, implementers, designers, and other stakeholders involved in post-disaster resettlement housing programs, offering insights for enhancing long-term satisfaction and sustainability in such programs.

“…Sleep disturbance factors in children included noise, lighting, uncomfortable sleeping bags, and heat, while the stiffness of the floor, uncomfortable pillows, noise, and cold were factors for adults. In our another prior study in the summertime, children’s sleep was severely disturbed during a one-night stay in a gymnasium, mainly due to heat, even at an ambient temperature of around 26°C [ 5 ]. These previous studies suggest that environmental factors, especially thermal discomfort, are among the most important elements affecting sleep in shelters.…”

“…Furthermore, bed climate humidity higher than 70% is related to sleep disturbance under high ambient temperatures in adults [ 9 ]. In school-aged children, the bed climate temperature of the foot area in summer and fall is maintained at 28–30°C, 50–70% RH when sleep is in the normal range [ 10 ]. However, to the best of our knowledge, it is still unknown whether the bed climate of school-aged children is related to sleep.…”

Background We investigated the relationship between sleep, ambient climate, and bed climate in school-aged children during a one-night stay in a simulated shelter in a gymnasium to demonstrate the effect of ambient climate, and bed climate on sleep. Methods We obtained measurements during a one-night stay in a school gymnasium (C), days before C (BC), on the day after (A1), and on the second day after C (A2) in 13 healthy school-aged children during summer. Sleep was evaluated using an actigraph, and the temperature and humidity of the bedrooms in the participants’ homes and in the gymnasium were monitored for 3 days before and after C. The bed climate of the chest and foot areas was measured for two nights before and after C. The participants were asked to report on their subjective sleep estimations and thermal sensations two nights before and after C. Results The ambient temperature in C was significantly higher than that in BC at the initial 180 min, while it significantly decreased compared to A1 and A2 in the last 100 min. The ambient humidity was significantly higher in both C and BC compared to A1 and A2. The sleep efficiency index decreased significantly in C (43±4.8%) compared to other conditions. Sleep time was significantly shorter in C than in other conditions during the initial 195 min. The increase in the bed climate temperature of the chest area in C was significantly delayed compared to that in the other conditions, around the initial 30 min after the lights were off. Subjective estimation revealed that in C, 85% of the participants were out of their sleeping bag at sleep onset, and their sleep was disturbed by heat (77%). Conclusions Our study revealed that the disturbed sleep patterns observed with children in a simulated shelter may be related to a delayed increase in bed climate temperature in the chest area. This delayed increase could be related to the children not entering the sleeping bag and a delayed chest skin temperature increase during the sleep onset period.
