Um estudo da Liverpool John Moores University, na Inglaterra, publicado em 3 de setembro no Journal of Applied Physiology, revelou que adultos jovens que ingerem menos de 1,5 litro de \u00e1gua por dia apresentam uma resposta de cortisol \u2014 o horm\u00f4nio ligado ao estresse \u2014 at\u00e9 50% maior em compara\u00e7\u00e3o com aqueles que consomem as quantidades recomendadas, de dois litros para mulheres e 2,5 para homens.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Os pesquisadores acompanharam 62 volunt\u00e1rios saud\u00e1veis, divididos em dois grupos, durante uma semana, monitorando a ingest\u00e3o di\u00e1ria de l\u00edquidos, exames de urina e sangue para medir o estado de hidrata\u00e7\u00e3o.

A urina mais concentrada e escura foi um dos sinais objetivos de que, apesar de n\u00e3o perceberem, os participantes estavam em estado de sub-hidrata\u00e7\u00e3o.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De acordo com os autores, a resposta exacerbada do cortisol preocupa porque est\u00e1 associada a riscos aumentados de doen\u00e7as cr\u00f4nicas, como problemas card\u00edacos, diabetes e depress\u00e3o.
