No, drinking excess water is not okay. While staying hydrated is crucial for health, consuming too much water too quickly can have serious consequences.
Dangers of Excessive Water Intake
The human body needs water to function properly, but the kidneys have limitations. They can only process about 0.8 to 1.0 liters of water per hour. Exceeding this limit can disrupt the body's delicate electrolyte balance, leading to problems. This condition, known as overhydration or water intoxication, can be dangerous.
