Although mixed methods research proves significant in understanding complex social phenomenon, inadequate research has explored its utility in heat exposure studies. The convergent mixed methods analysis comprising 320 surveys and two focus group interviews were used to evaluate the social impacts of occupational heat stress on Ghanaian mineworkers to enlighten policy choices for the purpose of complementarity. The study contributes to mixed methods study by affirming the practical use of between-method triangulation and complementarity. The merged quantitative and qualitative results also showed adequate corroboration and complementarity between both data, to illustrate the social impacts of work-related heat stress on mining workers as heat-related comorbidity, productive capacity loss, anxiety, slow pace of work, and inadequate social well-being. The mixed methods results would inform policy options on the health and safety of work settings, managing occupational heat stress, and adaptation guidelines in the mining industry.
