[Effects of temperature changes due to climate change on human health]

Climate change is intensifying extreme heat with serious health consequences. Heatwaves increase both mortality and morbidity, particularly affecting vulnerable groups. Heat exacerbates cardiovascular, renal, mental, and respiratory diseases, and its impact is greater in contexts of energy poverty and inadequate housing. Moreover, there are significant geographical and social inequalities: those who contribute the least to climate change are often the most affected. Adaptation can reduce heat-related mortality by up to 80% and includes physiological, cultural, technological, and policy-based measures. From Primary Health Care, strategies are proposed at individual, group, community, and political levels, focusing on identifying vulnerabilities, raising awareness, promoting healthy environments, and demanding climate justice. The approach must be comprehensive, equitable, and transformative in order to address this global health crisis effectively.
