ARE YOU GETTING ENOUGH LIQUID?
Monitor these three variables for a few days (always do so first thing in the morning) to find out. A positive result on two of them suggests that your fluid intake is inadequate – and if you get a yes for all three, it’s highly likely you’re low on liquid.
WEIGHT
More than 1% weight loss is a red flag.
URINE
Dark pee suggests inadequate fluid.
THIRST
A conscious desire for water.
