Drinking too much water can lead to water intoxication, which occurs when the balance of sodium in your system is overwhelmed by excess water. For most adults, consuming more than 3.5 liters (about 0.92 gallons) of water per day might be considered excessive, but this can vary based on activity level, climate, and individual health. It's crucial to listen to your body and drink when thirsty, rather than adhering strictly to a set amount.
