How Much Water Do You Really Need?
You’ve heard “eight glasses a day” forever — but real hydration is more personal than that, and the quality of what you drink matters just as much as the amount.
How much, really
The eight-glasses rule is a rough guide, not a law. Your needs shift with your size, your activity, the weather, and what else you’re eating and drinking. Let thirst, and the color of your urine (pale straw is the target), guide you.
Activity & weather
Move more, sweat more, or spend a hot day outside, and you simply need more — sometimes a lot more. Sip through the day rather than gulping it all at once.
A word on electrolytes
When you’re sweating hard or it’s very hot, water alone isn’t quite enough — a pinch of salt, a squeeze of citrus, or an electrolyte drink helps your body actually hold on to it.
Signs you’re running low
Headache, fatigue, poor focus, dark urine, and that mid-afternoon slump are often just mild dehydration. A glass of water is the cheapest fix in wellness.
The quality of your water
Amount is only half of it. A good filter — NSF-certified, matched to what’s in your local water — removes chlorine and can reduce contaminants like PFAS. Filtered water simply tastes better, too, which makes you drink more of it. (More in the Toxic-Free Kitchen.)
Make it a habit
A glass when you wake, a bottle you carry, water with every meal. Add cucumber, lemon, or mint if plain feels dull. The best hydration habit is the one you’ll actually keep.
Don’t count to eight — just drink filtered water through the day, more when you’re active, and listen to your body. Steady, unglamorous habits are what keep you well, not perfect tallies.
When the mind needs somewhere to land
Eating well is one kind of care; the nervous system is another. It is why I built SOVA — a quiet companion for the moments in between.
