Sponge7 Subtle Signs You Are Dehydrated (That Are Not Thirst)
Thirst is a late signal. Long before you feel it, mild dehydration shows up as afternoon fatigue, brain fog, headaches, dry skin, irritability, sugar cravings, and dark-colored urine.
The problem is that these symptoms are easy to blame on something else — a bad night of sleep, too much screen time, a skipped meal. That is why so many people are chronically under-hydrated without realizing it.
Passive tracking removes the guesswork. When Sponge shows that you have only had 600ml by 3pm, the cause of that 3pm slump suddenly becomes obvious — and fixable.
