Indoor RH levels frequently decline during heating seasons or in highly conditioned indoor environments, potentially affecting mucosal hydration and voice function among occupants—particularly those with high vocal demands. However, the effect size of such indoor environmental conditions on voice function remains unclear. This systematic review and meta-analysis was conducted to assess the effects of low (16%–35%) or very low (< 1%–5%) RH on various voice measures: acoustic (jitter% and shimmer%), aerodynamic (phonation threshold pressure on high pitch [PTP-80], modal pitch [PTP-20], and low pitch [PTP-10]), and self-evaluative (vocal effort in cm). To achieve this, we comprehensively searched the MEDLINE, CENTRAL, Scopus, and Web of Science databases, as well as manual sources, from inception to January 2026. PRISMA guidelines were followed, and GRADE was used to evaluate the certainty of evidence. The results are presented in terms of mean differences (MDs), 95% confidence intervals (CIs), <i>p</i>, and Cohen′s <i>d</i> values with random-effects model. Fifteen observational intervention studies with a pre–post design included 370 participants and 469 evaluations of the effects of very low (249 evaluations) and low (220 evaluations) RH, with 99 participants from three studies contributing to two or three evaluations. Indirect comparisons between low and very low RH showed no significant differences for PTP-80, PTP-10, and vocal effort (<i>p</i> > 0.05), indicating that even moderately low indoor RH levels commonly observed in buildings are sufficient to induce voice changes. Adverse effects at low or very low RH were confirmed for PTP-20 (MD = 0.20 [95% CI, 0.02–0.37]; <i>d</i> = 3.59 [95% CI, 1.96–5.22]; moderate certainty), PTP-10 (MD = 0.29 [95% CI, 0.07–0.51]; <i>d</i> = 3.67 [95% CI, 1.94–5.40]; moderate certainty), jitter% (MD = 0.33 [95% CI, 0.26–0.39]; <i>d</i> = 4.62 [95% CI, 3.35–5.90]; low certainty), and shimmer% (MD = 0.62 [95% CI, 0.34–0.89]; <i>d</i> = 3.75 [95% CI, 2.24–5.25]; low certainty). Subgroup analyses showed a greater impact on individuals with voice problems.

We reviewed studies on the impacts of residential retrofits on indoor environmental quality and energy consumption. Previous studies reported that retrofitting reduces energy consumption by 10%–84%. Indoor temperatures generally rise when retrofitting targets winter and decrease when targeting summer. However, effects on relative humidity, carbon dioxide, and air pollutant concentrations varied with ventilation, occupant behavior, and outdoor pollution levels. Overall, the effects of large-scale retrofit on indoor environmental quality and health remain uncertain because most studies lacked a causal framework, long observation periods, adequate sample sizes, weather adjustment, matched control homes, and control for occupant behavior.

Drawing on a large-scale household survey (<i>N</i> = 543 participants), the study adopts a multidomain approach integrating perceived thermal, lighting, acoustic, indoor air quality (IAQ) comfort, alongside odor perceptions. Principal component analysis (PCA) and multiple linear regression (MLR) were used to examine how building characteristics and sociodemographic factors influence perceived IEQ in Dubai residential buildings within a rapidly-urbanizing, hot–arid, and demographically diverse context. Findings showed elevated dissatisfaction linked with dust exposure and thermal extremes, reflecting environmental challenges typical of desert climates and mechanically cooled housing. PCA identified two latent IEQ constructs: a multisensory comfort component integrating thermal, lighting, and acoustic perceptions; and an IAQ component driven by pollutant exposure and olfactory sensitivity. MLR results showed that perceived IEQ differed according to demographic, health, and sociocultural characteristics: dust allergy and migraine were associated with higher frequencies of perceived discomfort across all IEQ domains; passive smoking was associated with increased thermal–lighting–acoustic discomfort and odor perception; whereas perceived IAQ dissatisfaction was additionally associated with older age and African nationality. Results also demonstrated significant associations with building-related factors, including ventilation systems, moisture-related issues, and material emissions: water leakage was significantly associated with higher discomfort across IEQ domains; new carpets were associated with increased odor perception and thermal–lighting–acoustic discomfort; whereas split HVAC systems were associated with odor perceptions, indicating ventilation limitations.

Participants in the highest ECQI tertile had higher odds of subjective sleep disorders, for both the unweighted score (OR = 1.25, 95% CI: 1.07–1.46; <i>p</i><sub>trend</sub> = 0.004) and the weighted score (OR = 1.19, 95% CI: 1.04–1.37; <i>p</i><sub>trend</sub> = 0.010). For the highest index category (≥ 2), the OR was 1.45 (95% CI: 1.08–1.94; <i>p</i><sub>trend</sub> = 0.030) for IEQI. Moreover, higher odds were also observed in participants reporting noise around the home (OR = 1.33, 95% CI: 1.14–1.56) or smoke-related irritation symptoms (OR = 1.46, 95% CI: 1.21–1.76).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Poorer participant-reported residential environmental quality was associated with higher odds of subjective sleep disorders, with an association observed for indoor environmental quality.</p>\u0000 </section>\u0000 </div>","PeriodicalId":13529,"journal":{"name":"Indoor air","volume":"2026 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/ina/1542821","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148994248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the severe acute respiratory syndrome (SARS) outbreak did not lead to sufficient reflection, resulting in the coronavirus disease 2019 (COVID-19) pandemic surpassing SARS in scale. Many countries struggled to keep up with the rapid spread of the virus, leading to shortages of medical supplies and immense pressure on frontline healthcare workers, further highlighting the importance of medical resource classification. This study explores the adaptation of 20-foot shipping containers into frontline screening stations to effectively separate existing medical resources. It considers national standards for pressure differentials and air change per hour (ACH) in medical spaces (noting that specific regulations for screening stations are currently lacking) and analyzes key environmental factors affecting indoor conditions, including temperature, humidity, carbon dioxide concentration, and power consumption. The results indicate that maintaining an ACH of 10 times (10 h<sup>−1</sup>) and a pressure differential of 2.5 Pa (positive or negative pressure), along with good airtightness, can effectively sustain indoor environmental quality in screening stations. Additionally, incorporating external ventilation fans enhances the adaptability of these stations, ensuring their usability both during and beyond pandemic periods.</p>","PeriodicalId":13529,"journal":{"name":"Indoor air","volume":"2026 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/ina/8884299","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148994116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
