The team asked volunteers to perform a repetitive task\u0026mdash;pushing a specific button when a yellow square appeared on a monitor\u0026mdash;for 20 minutes without hydrating. Even when no dehydration is present, the authors noted that \u0026ldquo;exertion and heat\u0026rdquo; can have a negative impact on a person\u0026rsquo;s ability to function\u0026mdash;when dehydration does kick in, it just makes that negative impact that much worse. \u0026ldquo;We wanted to tease out whether exercise and heat stress alone have an impact on your cognitive function and study the effect of dehydration on top of that,\u0026rdquo; principal investigator \u003Cstrong\u003EMindy Millard-Stafford\u003C\/strong\u003E, PhD, a professor at Georgia Tech, said in a prepared statement. \u0026ldquo;We found a two-step decline.\u0026rdquo; \u003Ca href=\u0022https:\/\/www.business-standard.com\/article\/news-ani\/how-dehydration-affects-your-brain-118082200096_1.html\u0022\u003EBusiness Standard also covered the work here\u003C\/a\u003E.\u003Cbr \/\u003E\r\n\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":"","uid":"30678","created_gmt":"2018-08-28 12:32:54","changed_gmt":"2018-08-28 12:32:54","author":"A.
