In high closeness scenarios, a room’s temperature, humidity, and ventilation play crucial roles. Excessive heat and low humidity hinder sweat evaporation, intensifying the sensation of closeness. Inadequate air circulation, overcrowding, and closed spaces exacerbate the issue by trapping heat and moisture. Malfunctioning air conditioning or heating systems, poor insulation, and lack of air movement further contribute to uncomfortably high temperatures in enclosed spaces.
