Have you ever thought that drinking too much water could be harmful to your health? How much water is too much? How can we recognize that we have exaggerated?

Water is essential for our health and well-being. It consists of more than 60 % of the body weight of an adult and is essential for the functioning of our organs, regulating body temperature and removing toxins from the body. While drinking enough fluids is important, drinking too much water can cause serious health problems.

Excessive drinking of water, also known as water intoxication or hyponatremia, can lead to an electrolyte imbalance in the body, which can be dangerous. That is why it is important to know how to recognize warning signs that it's time to take a break.

Frequent urination

If you notice that you need to go to the bathroom every 30 minutes or more, this could be a sign that you are drinking too much water. It is normal to go to the toilet about 6-8 times a day, but if you significantly exceed this number, consider reducing your fluid intake.

Pale urine

Although bright yellow urine is a sign of adequate hydration, completely pale or almost clear urine may indicate that you are flooding your body with water. Urine should have a slightly yellowish color, which indicates that the body has the right balance of fluids.

Feeling bloated

If we drink too much liquid, our stomach can become bloated and we feel uncomfortable. If you notice this feeling, try reducing the amount of water you drink and see if your symptoms improve.


Hyponatremia caused by drinking too much water can cause brain swelling, leading to headaches. If you have frequent or severe headaches and have noticed that you are drinking a lot of water, this may be a warning sign that you need to reduce your fluid intake.

Confusion and disorientation

There are two other serious warning signs of hyponatremia. When sodium levels in the blood drop too low, it can affect brain function, causing feelings of confusion, dizziness, and even disorientation. If you experience these symptoms, stop drinking the water immediately and seek medical attention.

Muscle cramps and weakness

The electrolyte imbalance caused by excessive drinking can affect muscle function and cause cramps and a feeling of weakness. It is important to consume foods rich in electrolytes, such as bananas, nuts and yogurt, in addition to water.

Most experts recommend drinking approx 2-3 liters of fluid per day, but these needs may vary depending on physical activity, the climate and individual needs.
