Feeling tired, dizzy, or like your mouth is full of cotton? That’s your body waving a white flag. Drink a few ounces pronto. If you’re exercising for more than an hour, or it’s hotter than a dragon’s breath outside, add 8-16 extra ounces per hour of activity. Your sweat glands are basically tiny waterfalls—help them out.
On the flip side, don’t force yourself to chug if you’re not thirsty. Overhydration (called hyponatremia) is rare but real—it’s when you dilute your blood’s sodium levels. It’s like trying to water a plant that’s already swimming. So listen to your body: if your stomach sloshes when you walk, you’ve probably had enough.
The ultimate rule? Drink when you’re thirsty, pee when you need to, and aim for that 64-80 ounce sweet spot most days. You’re not a science experiment; you’re a human with a vibe.
