Resumo

Semelhante às catástrofes provocadas pela natureza como terremotos e inundações, as ondas de calor geradas pelo aquecimento global também provocam muitas mortes. Em novembro passado, durante a terceira etapa de uma competição de Montain Bike dentro do Parque Nacional da Serra da Capivara (PI), uma competidora sentiuse mal, vindo a falecer após percorrer parte do trajeto sob sol forte a uma temperatura de aproximadamente 42°C. acredita-se que a causa tenha sido hipertermia. A hipertermia é o aumento da temperatura corporal por falência dos mecanismos de dissipação do calor, para se contrapor à febre onde há falência da regulação hipotalâmica. São cinco as formas de manifestação clínica: edema, cãibras, síncope, exaustão e hipertermia. Parece haver alguma relação entre hipertermia maligna e hipertermia por esforço. Apesar do grande número de mortes pouco se ouve falar sobre os riscos da hipertermia por exposição ao calor e menos ainda sobre a manifestação dos sintomas. Foram analisados os estudos que investigaram os fenômenos associados às doenças induzidas por calor e suas conseqüências no organismo. Para a localização dos artigos, foi criada uma estratégia de busca em bases de dados na Internet por meio de .palavras-chave., onde se estabeleceu a relação entre hipertermia e exercício.
