Abstract

Rising global temperatures and increasing frequency of extreme heat events have transformed thermal stress into a critical, systemic driver of cardiovascular and chronic disease burden worldwide. Despite growing recognition of heat-related health risks, substantial gaps remain regarding chronic sub-threshold exposure, morbidity outcomes, and the equity implications of adaptation strategies. This systematic review, conducted according to PRISMA 2020 guidelines, synthesizes contemporary epidemiological evidence from peer-reviewed studies published between 2020 and 2025 to characterize heat-health associations, identify vulnerability determinants, and evaluate policy implementation across diverse geographic and socioeconomic contexts. Following independent screening, quality appraisal, and data extraction, a structured narrative synthesis was performed due to significant methodological heterogeneity in exposure metrics and outcome definitions. The findings demonstrate a robust association between heat exposure and elevated risks of stroke, coronary heart disease, and accelerated progression of metabolic, respiratory, and mental health conditions, with chronic thermal stress emerging as an underrecognized contributor to long-term physiological deterioration. Vulnerability is highly stratified, disproportionately affecting older adults, women, outdoor workers, socioeconomically marginalized communities, and populations in low- and middle-income countries, particularly within urban heat island environments. Current adaptation measures exhibit limited behavioral uptake and insufficient equity-focused design. Addressing these disparities requires standardized exposure metrics, context-sensitive early warning systems, multisectoral policy integration, and targeted research on chronic thermal stress to build inclusive, climate-resilient health systems.

Abstract

Digital competency is a challenge and necessity for educators in the 21st century, especially in vocational schools. This study aims to bridge the gap by comprehensive review of digital media as a component of digital competency for teachers in Vocational Education and Training (VET). Data were collected from the Scopus, Research Gate, and Scholar databases based on inclusion and exclusion criteria. This study employs content analysis on 11 articles published in international journals indexed by Scopus between 2018 and 2024. The stages carried out include formulating material based on research questions, selecting relevant journal articles, analyzing main topics, interpreting data, identifying categories to develop digital skills, reporting findings, drawing conclusions, and suggesting further research. The findings show several technologies to develop educators' digital competence, such as blogs, websites, mobile smartphones, video conferencing, digital content and new digital devices. Project-based learning as an alternative instructional model for developing digital competencies using digital media. Digital media influences digital competence and its domain. Future studies could carry out empirical investigations based on this finding to further enhance digital competence among VET teachers.
