Condições biometeorológicas nas aulas de educação física escolar em Bambuí - MG

Climate crisis has increased health risks, particularly during outdoor physical activities. In the school context, Physical Education classes represent a sensi-tive environment, especially for children and adolescents whose thermoregula-tory systems are still developing. This study aimed to analyze the climatic and biometeorological conditions during Physical Education classes at the Federal Institute of Minas Gerais, Bambuí campus, in 2024 and 2025. A descriptive-exploratory longitudinal design was adopted, using secondary data from the National Institute of Meteorology’s automatic weather station and the IQAir® platform. Climatic variables (air temperature, relative humidity, and solar radia-tion) and biometeorological indices—including the Wet Bulb Globe Tempera-ture (WBGT), Thermal Discomfort Index (TDI), Temperature and Humidity Index (THI), Heat Index (HI), and fine particulate matter concentration (PM2.5)—were analyzed according to class schedules. The results showed that afternoon pe-riods, particularly after 1:00 p.m., presented the most critical conditions, with elevated temperature, solar radiation, and WBGT values, frequently classified as high or very high risk to comfort and health. Although air quality remained within national standards, PM2.5 concentrations exceeded World Health Or-ganization guidelines. These findings indicate the need for pedagogical and organizational adaptations to ensure health protection, safety, and well-being in school Physical Education settings.
