Can Drinking Too Much Water be Dangerous?

As we know, most of our body consists of liquid H2O so it is very important for the body to have enough water content. Water is present in the bloodstream, filling cells and cavities between cells. The body also regulates the expenditure of water to maintain balance. However, what happens if the body contains too much water?

Drinking too much water can disrupt the ion balance

In fact, not all of the water we drink has ions needed by the body, while ions often come out with sweat in the form of salt. Consumption of too much water, without the added balance of salt intake from food and beverages, will reduce the concentration of salt in the blood. The concentration of salt in the bloodstream itself is needed to maintain blood pressure, work muscles and nerves to stay normal. Salt in the blood also affects the work of the kidneys in regulating water storage and preventing the body from storing too much water.

The concentration of normal salt in the blood ranges from 135-145 mmol /liter. Consumption of too much water can reduce blood salt concentrations up to around 115-130 mmol and trigger various decreases in blood function because it becomes more fluid.

Symptoms that occur in the body during "water poisoning" due to drinking too much

Drinking too much water in a short time can lead to water poisoning or overhydration. This condition begins with storing water in the body because the kidneys cannot regulate water, due to an ion imbalance. Water that cannot be re-absorbed is absorbed in the bloodstream, and eventually the body that stores too much water causes enlargement of various cells of the body so that it interferes with the function of the cell itself.

If cell enlargement occurs in brain cells, this can cause pressure in the skull to increase. This triggers various initial symptoms of water poisoning such as headaches, nausea, and vomiting. Symptoms can develop into a temporary decrease in cognitive function such as feeling confused, having difficulty thinking, and experiencing disorientation.

In more serious cases, water poisoning also causes muscle cramps and difficulty breathing accompanied by failure of brain function. Serious swelling of the brain can also occur due to cells storing too much water, causing seizures and even death.

What causes a person to be overhydrated?

It is very difficult for someone to consume too much water accidentally, because water cannot cause addiction. However, there are several reasons why someone drinks too much water and causes an overdehyde condition.

1. Drink lots of water intentionally

It was recorded previously that someone drank so much water to win a contest or game. Without realizing it, consumption of excess water causes poisoning and ultimately causes death.

2. Drink too much water by reason of preventing dehydration

This condition is often experienced by athletes or soldiers while undergoing training with heavy physical activity. But precisely this can lead to overdehyde. This is because when experiencing stress, the body has its own mechanism to regulate the discharge of fluid by secreting antidiuretic hormones, so that the body can store more fluids, and consumption of excess water will only make the condition overhydration.

3. The desire to drink water due to disease conditions

This can occur in individuals who have diabetes or are undergoing treatment with side effects that trigger dry mouth. The desire to drink or thirst is not a sign when the body experiences a lack of fluids but only the body's response to interference, and drinking too much water can still trigger overhydration.

4. Having schizophrenia

Schizophrenia is a psychiatric condition that makes it difficult for a person to stop doing something, including one that consumes water. If this happens it will be very dangerous for people with schizophrenia because they are unaware and cannot stop water consumption alone.

5. Other medical conditions

In addition, the symptoms of overdehydration without drinking too much water can also be caused by several diseases that trigger more water storage, such as:

  • Liver disease
  • Kidney disease
  • Congestive heart failure
  • Disorders of anti-diuretic hormone secretion

How to deal with overhydration

Overhydration is often characterized by nausea and dizziness shortly after drinking too much water. To prevent it from getting worse, immediately stop consuming water in the foreseeable future and give diuretic drugs to trigger urinary secretion. Symptoms of headaches, seizures, and nausea can be overcome by giving treatment according to the symptoms experienced by the sufferer.

What is the maximum limit of water intake in a day?

One reason someone drinks too much water in too short a time is when feeling thirsty excessively after exercising or having heavy physical activity. To avoid this, consume water at 15-30 minutes before physical activity to avoid drinking too much after physical activity. Avoid drinking more than one liter of water in one hour.

Daily water requirements for normal people in general are only about 3.7 liters of water for men, and 2.7 water for women, and this includes the water content of other foods and drinks. In addition, the easiest and safest way to fulfill sufficient drinking water is to immediately drink enough water every time you feel thirsty.
