Os cientistas examinaram a pele daqueles que eram os ímãs dos pernilongos e encontraram 50 compostos moleculares que eram mais comuns nesses participantes do que nos outros

Uma diferença era particularmente chamativa: os "ímãs de pernilongos" tinham taxas muito mais altas de ácido carboxílico em sua pele do que os atratores baixos

O calor do corpo e o dióxido de carbono que liberamos atraem os pernilongos Pexels/Karolina Grabowska

Com mais pesquisas sobre o microbioma da pele humana, pode ser possível produzir produtos melhores para reduzir as picadas de mosquitos e a propagação de doenças
