A healthy adult's kidneys can remove 20 to 28 liters of water per day, but only about 1 liter per hour. This makes it harder for your kidneys to keep up if you drink more than 1 liter per hour.

Most reported cases of life-threatening water intoxication have been associated with intense physical activity, such as military training or running a marathon. Others are due to excessive water consumption due to an underlying mental illness or forced consumption as a form of abuse.
Water intoxication has also been linked to the use of the drug MDMA, particularly at music festivals. This is because people in these environments often dance in hot environments for long periods of time. This, combined with MDMA's tendency to raise your body temperature, can make you drink a lot of water.
