Agua

Q: Can you drink too much water if you keep drinking until you are no longer thirsty?

A: No. If you stop drinking water when you stop feeling thirsty, you are not at risk for overdosing on water or developing hyponatremia.

There is a slight delay between drinking enough water and not feeling thirsty anymore, so it's possible to overhydrate yourself. If this happens, you'll either vomit the extra water or else need to urinate. Even though you might drink a lot of water after being out in the sun or exercising, it's generally fine to drink as much water as you want. The exceptions to this would be babies and athletes. Babies should not drink diluted formula or water. Athletes can avoid water intoxication by drinking water that contains electrolytes (e.g., sports drinks).
