Almost everyone in the fitness, conditioning, and nutrition field mentions a minimum of 8 glasses of water per day. Most recommend a GALLON a day. Physicians see this as a fad. It may be largely promoted by companies that sell bottled water and water filters. Consumer Labs have tested over and over again that bottled water is NOT better than tap water. I remember when water was free and no one walked around with a constant liter or gallon sized bottle with them.
I can’t imagine how 1950’s laborers and athletes survived without a gallon jug around them for twenty four hours a day.

this has been a very interesting topic to me for years. from an evolutionary standpoint it makes no sense that our thirst mechanisms would be faulty; i.e that when we are thirsty “we are already dehydrated”.
this is the equivilant of when your cars check oil light comes on your oil is already empty!
and yet I cant deny how much better I feel when I stay more hydrated than my thirst would dictate,even if I eat water based foods( veggies and fruits).
oh yeah, and i’ve been drinking tap water since I read that stuff about bottled not being any better.
