Non-optimal temperature is a leading risk factor for global disease burden. Most epidemiological studies assessed only outdoor temperature, with important uncertainties on personal exposure misclassification. The CKB-Air study measured personal, household (kitchen and living room), temperatures in the summer (MAY-SEP 2017) winter (NOV 2017-JAN 2018) 477 participants China. After data cleaning, ∼88,000 person-hours of were recorded across each microenvironment. Using multivariable linear regression (MLR) random forest (RF) models, we identified key predictors constructed prediction models.

As the incidence of extended hot summers in Nordic climate increases due to change, non-mechanically cooled apartments face high risks overheating. Hence, this study aimed investigate temporal effects heatwaves on indoor temperatures and examine correlation between outdoor weather conditions temperature levels. A comprehensive field was conducted across over 6000 Helsinki region during summer 2021 its heatwaves. Results indicated that nearly half experienced above 27 °C for 7 consecutive days. It found an daily average 19 could cause higher than °C. Further, revealed a strong 5-day moving temperature, allowing occupants time take preventative measures. Additionally, linear relationship 7-day solar radiation. The strength magnitude radiation varied depending duration This highlights importance considering design renovation residential buildings climate.

Background Lifestyle modification is the cornerstone of non-alcoholic fatty liver disease (NAFLD) prevention and treatment. Short video platforms can facilitate easier access to health information for patients, thereby influencing lifestyle changes. An increasing number individuals rely on online acquire health-related about NAFLD. However, quality regarding NAFLD these remains unclear. Objective This study aimed investigate TikTok. Methods A total 497 videos were retrieved from The basic information, including source, was extracted. Two independent raters evaluated reliability using Global Quality Score system a modified DISCERN tool. Propensity score matching (PSM) used compare across sources. Results NAFLD-related TikTok divided into three groups according uploader: professionals, medical institutions, science bloggers. Overall, not satisfactory. Before PSM, there no significant differences in or content between groups. After professionals significantly better than created by other Besides, outperformed those institutions bloggers terms definition disease, risk factors, treatment, but inferior considering symptoms tests Conclusion needs improvement.

With the accelerated development of subways in China, elevated subway stations (ESSs) capitalize on natural ventilation and lighting to significantly save energy. Nevertheless, their thermal environments are rarely addressed. This study conducts annual environment measurements, surveys, comfort analysis five typical ESS buildings. The results field measurements demonstrate that station’s is influenced by architectural space forms such as skylight ratio, platform doors, openness, form. standard effective temperature—predicted sensation (SET*—PTS) equation was developed based survey, indicating passengers’ adaptability surpasses PTS. In summer, neutral temperatures for passengers open enclosed 28.74 SET* °C 27.13 °C, correspondingly. winter, they 23.43 21.98 °C.

Residents themselves are responsible for controlling their living environment, and perception of coldness is important to protect health. Although previous studies examined the association between perceived indoor temperature, they did not consider spatial–temporal differences in temperatures. This study, conducted Japan, measured temperatures 1,553 houses across several rooms (living room, changing bedroom) heights (at 1 m above floor near floor) over two weeks obtained from 2,793 participants during winter. Results showed substantial temperature (horizontal differences): 3.8 °C rooms, 4.1 bedrooms. The average vertical diel (evening-morning) room were 3.1 3.0 °C, respectively. Regional analysis revealed that Tohoku region experienced larger horizontal differences, primarily due its practice intermittent partial heating only, contrast Hokkaido's approach entire house continuously. Despite comprehensive system, it exhibited largest difference 5.1 highlighting insufficiency alone necessity enhanced thermal insulation. multivariate logistic regression analyses associated with coldness, while show a significant association, further emphasizing importance improved Moreover, factors like individual attributes (age gender), lifestyle choices (meal quantity, exercise habits, alcohol consumption, clothing amount) significantly perception. Notably, older adults less likely perceive but more vulnerable health impacts low temperatures, underscoring solely relying on human management cold-related problems.

Abstract Relative humidity and temperature in indoor spaces are two important environmental factors that not only determine the behaviour well-being of building occupants but also influence airborne transmission respiratory diseases closed spaces. While recent studies have examined how well conditions relate to outdoor ambient weather, most on weather-related health effects still use a single central site monitor such as weather station since values more convenient measure. However, correlation between is always straightforward. Our case study explores relationships residential apartment temperate climate Central Europe. Measurements performed over period one year allow for detailed comparison analysis correlations both daily averages profiles variables. The results this add further evidence observations day-to-day variation relative well-represented by measurements.
