Water, water, ev­ery­where

“Hy­dra­tion,” says Dr John Briffa, “is very im­por­tant. It’s been found that rel­a­tively mild de­hy­dra­tion, as lit­tle as 1pc, is enough to cause prob­lems around con­cen­tra­tion and mood.

“A lot of peo­ple will rec­om­mend two litres, or eight glasses of water,” con­tin­ues Dr Briffa. “All of this is non­sense re­ally be­cause the amount you need to drink varies enor­mously be­tween peo­ple and how much they’re sweat­ing, or what the weather is do­ing. You need to be drink­ing enough fluid to keep your urine pale yel­low; if you’re do­ing that, you’re al­most cer­tainly well hy­drated. Thirst is a pretty poor and late in­di­ca­tor of de­hy­dra­tion.”
