2. Increase the pressure on the cardiovascular system

Drinking too much water will increase the body's blood volume, this will increase the load on the heart and blood vessels. For people with a history of cardiovascular disease, there is an increased risk of heart failure. Therefore, people with cardiovascular disease drinking too much water will be very dangerous.

Manifestations of chronic disease are increased weight, pale and moist skin, symptoms of nausea or poor digestion, and neurological symptoms such as headache, delirium. At a low level, simply stopping or reducing the amount of water put into the body can stop the above conditions.

3. After hard work or vigorous exercise

When the body produces a large amount of sweat, it will cause a loss of salt in the body. This situation should avoid drinking too much water, causing the body in a short time to absorb too much water without timely salt addition will cause the concentration of electrolytes such as sodium ions in the blood rapidly decreases, thereby leading to to water poisoning.
