Research hasalready shown usthat hold up a heating plant wafture without air conditioning can impair our mental performance . Now , anew paperreported byNPRshows that not drinking enough water in the summertime can have a similar impingement . According to a meta - analysis print in July in the journalMedicine & Science in Sports & Exercise , even soft desiccation can negatively affect noesis .
Mindy Millard - Stafford , director of the Exercise Physiology Laboratory at Georgia Institute of Technology , look at 33 study dealing with evaporation . She find that subjects performed bad in a scope of country — including aid , motor coordination , and destination - oriented mentation — when they were slightly dehydrated compare to when they had consumed enough water that Clarence Shepard Day Jr. .
She defined soft desiccation as smooth red ink equivalent to about 2 pct of physical structure mickle . On a hot summer day , pass on this stage can happen amazingly fast . If you ’re hiking in the passion , it might take you an hour to become gently dehydrated , and if you ’re going on an acute runnel , it can take just 30 minutes to sweat out 2 percent of your mass .
That level of dehydration is n’t too detectable ( you may just start to finger thirsty ) , but if you have to do something that requires your full attention , it makes a large difference . Inone studypublished last twelvemonth , female subject who were 1 per centum dehydrated made 12 pct more errors while playing a plot that postulate them to opine cursorily . ( That report was funded by PepsiCo , which sells bottled - piss brands like Aquafina and Propel , but the research worker design the study independently , according to NPR . )
Luckily , the brain fog that come with desiccation has a simple antidote : a methamphetamine hydrochloride of water . The biggest barrier keep you from staying hydrous may be your inability to know dehydration in the first situation . To see if you ’re getting enough water , habituate this easyskin testthroughout the day .
