We're constantly told to hydrate, hydrate, hydrate! But can you actually *over*hydrate? The answer, surprisingly, is yes. While rare, drinking too much water, too quickly, can lead to a dangerous condition called hyponatremia.
Hyponatremia occurs when sodium levels in your blood become dangerously diluted. Sodium helps regulate fluid balance, and excessive water intake can throw this balance off, causing cells to swell. Symptoms can range from nausea and headache to confusion, seizures, and even coma in severe cases.
So, how much water *is* too much? It depends on factors like your activity level, climate, and overall health. A good rule of thumb is to drink when you're thirsty, and to listen to your body. Avoid chugging large amounts of water, especially during intense exercise. Aim for pale yellow urine – a good indicator you're adequately hydrated. If you suspect you've consumed too much water and experience any symptoms, seek medical attention immediately. Remember, moderation is key, even with something as vital as water!
