Water-related headaches feel different from your usual tension headache. They’re usually dull, spread across your whole head, and come with a side of nausea or brain fog. It’s like your head is wrapped in a wet towel—and not in a spa-day way.
Another clue: your pee turns clear as tap water. Healthy urine should be a pale lemonade color. If it’s crystal clear, you’ve probably been overdoing it. Congratulations, you’re officially a water overachiever.
What about caffeine?
Here’s where it gets tricky. If you drink a ton of water but skip your morning coffee, you might still get a headache. Caffeine withdrawal is a real jerk, and it can mimic the “too much water” feeling. So maybe you’re not a water-poisoning victim—you’re just a grumpy person who needs their caffeine fix.
I once tried to “detox” with only water for a day. By noon, I had a headache that made me want to apologize to everyone I’ve ever annoyed. Turns out, my brain runs on a blend of coffee and moderate hydration—not a fire hose.
