If sodium levels fall below 135 millimoles per liter (mmol/50), doctors refer to the issue as hyponatremia.

Sodium helps maintain the balance of fluids within and outside of cells. When sodium levels drop due to excessive water consumption, fluids travel from the exterior to the within of cells, causing them to swell.

When this happens to encephalon cells, it can be dangerous and fifty-fifty life threatening.

Bottom line: Water intoxication results from drinking too much water. The excess water dilutes sodium in the blood and causes fluids to move within cells, causing them to swell.

When a person consumes an excessive amount of water and cells in their brain start to not bad, the pressure inside their skull increases. This causes the kickoff symptoms of water intoxication, which include:

  • headaches
  • nausea
  • airsickness

Severe cases of h2o intoxication tin can produce more serious symptoms, such as:

  • drowsiness
  • muscle weakness or cramping
  • increased claret pressure
  • double vision
  • confusion
  • inability to identify sensory data
  • difficulty breathing

A buildup of fluid in the brain is chosen cerebral edema. This can touch on the brain stalk and cause central nervous system dysfunction.

In severe cases, water intoxication tin can cause seizures, brain damage, a blackout, and even death.

Lesser line: Drinking as well much water can increase the pressure level within the skull. This can cause diverse symptoms and, in severe cases, become fatal.

Water intoxication is rare, and it is very difficult to consume too much water past accident. Withal, it can happen — there have been numerous medical reports of death due to excessive h2o intake.

Water intoxication most commonly affects people participating in sporting events or endurance preparation, or people who take diverse mental health weather condition.

Sporting events

Water intoxication is particularly common among endurance athletes. It can happen if a person drinks a lot of water without correctly bookkeeping for electrolyte losses.

For this reason, hyponatremia often occurs during major sporting events.

As the authors of one study report, out of 488 participants in the 2002 Boston Marathon, 13% had hyponatremia symptoms, and 0.06% had critical hyponatremia, with sodium levels of less than 120 mmol/l.

Instances of water intoxication at these events accept resulted in death. One instance involved a runner who had collapsed afterward a marathon.

Because he was improperly rehydrated, his sodium levels fell below 130 mmol/l. The runner then developed water on the brain, known as hydrocephalus, and a hernia in his brain stem, which caused his death.

War machine training

I medical report described 17 soldiers who developed hyponatremia after drinking too much water during training. Their blood sodium levels were 115–130 mmol/l, while the normal range is 135–145 mmol/fifty.

According to some other report, three soldiers died due to hyponatremia and cognitive edema. These deaths were associated with drinking more than 5 liters of water in merely a few hours.

The symptoms of hyponatremia can exist misinterpreted every bit those of dehydration. Co-ordinate to one report, a soldier who received an incorrect diagnosis of dehydration and heat stroke died from water intoxication as a effect of rehydration efforts.

Mental health conditions

Compulsive h2o drinking, besides chosen psychogenic polydipsia, can be a symptom of diverse mental health weather.

It is nigh common amid people with schizophrenia, merely it can also arise in people with affective disorders, psychosis, and personality disorders.

Bottom line: Water intoxication can be life threatening, and information technology is almost common among soldiers in preparation, endurance athletes, and people with schizophrenia.

Information technology is difficult to consume likewise much water by accident. Nevertheless, information technology tin happen, and there take been numerous reports of death due to excess h2o intake.

People at risk of decease from water intoxication tend to be participating in endurance sporting events or armed forces training. A person who is doing neither is unlikely to dice from drinking besides much water.

Overhydration and water intoxication happen when a person drinks more water than their kidneys can go rid of via urine.

The amount of water is not the just factor — time too plays a part.

Co-ordinate to figures quoted in a 2013 study, the kidneys tin can eliminate about 20–28 liters of h2o a 24-hour interval, but they can remove no more than than 0.viii to ane.0 liters every hour.

To avoid hyponatremia, it is important not to outpace the kidneys by drinking more than water than they can eliminate.

The authors of the report report that hyponatremia symptoms can develop if a person drinks 3–4 liters of h2o in a brusque menstruation, though they do not give a specific time approximate.

According to one case report, soldiers adult symptoms after consuming at least two quarts (one.9 liters) of water per hr.

Another study describes the development of hyponatremia later on drinking more than than five liters in a few hours.

Water intoxication and prolonged hyponatremia also occurred in an otherwise healthy 22-year-old prisoner who drank 6 liters of water in iii hours.

Finally, co-ordinate to one report, a 9-twelvemonth-former daughter developed water intoxication afterward consuming 3.6 liters of h2o in 1–ii hours.

Bottom line: The kidneys can remove 20–28 liters of water per day, but they cannot excrete more than 0.viii to ane.0 liters per hr. Drinking more than than this tin can be harmful.

According to the Centers for Illness Control and Prevention (CDC), there are no official guidelines nearly how much water a person needs to drink each day.

The right corporeality differs, depending on factors such every bit body weight, level of physical activity, the climate, and whether they are breastfeeding.

In 2004, The National University of Medicine recommended that women aged 19–30 consume around 2.seven liters per day and men of the aforementioned age around 3.seven liters per twenty-four hours.

Some people still follow the 8×8 rule, which recommends drinking viii 8-ounce glasses of water per day. However, this was not based on research.

Relying on thirst may not work for everyone. Athletes, older adults, and pregnant women, for instance, may need to drinkable more water each solar day.

To estimate the right corporeality, it can assistance to consider calories. If a person needs ii,000 calories per day, they should also consume 2,000 milliliters of water per day.

Drinking too much water can atomic number 82 to water intoxication. This is rare and tends to develop among endurance athletes and soldiers.

There are no official guidelines almost how much water to drink. To avoid water intoxication, some sources recommend drinking no more than 0.8 to 1.0 liters of water per hr.
