Should we be drinking like fish?
It’s a simple answer, and you won’t even need to keep checking the back of your underpants!
Feel the natural cycle of your body (and the cosmic energy of the universe BRO!) and just knock it back when you are thirsty.
Put it this way, drinking to the exact ‘recommendations’ of medical sources, 1.6; 2 litres (female; male) [NHS 2013] won’t hold true between Ronnie the pensioner and Terry the bodybuilder.
An exact figure would weigh up; water taken up from food/beverages versus water lost from climate, energy expenditure, diet osmolarity, body mass and individual thermoregulation variants.
But your body does this for you with a thing called THIRST! The problem of dehydration often comes when we don’t pay attention to those signals, especially in hot weather.
So it can be helpful to make sure you drink a certain amount per day, especially if you’re busy, but too much water will simply result in more excretion within the hour.
