We talked about the importance of water in our last article "Water". Now we know what will happen if you drink too little but the question is, what will happen if you drink TOO MUCH!! Is it even possible to drink too much?! You know you can die from too much water?!
Today we will talk about what will happen if you got what is called Water intoxication also known as water poisoning.
Water poisoning is the disruption of your brain function due to drinking too much water! Yes that's true. (1) When you drink too much water it increases the amount of water in your blood which dilutes the electrolytes in the blood causing sodium levels to fall below 135 mmol/L, it's called Hyponatremia.
Sodium is a very important element for your body, it's responsible for the balance of fluids between the inside and the outside of the cells. So when sodium levels falls below 135 mmol/L, fluids shifts from the outside to the inside of cells causing them to swell. A problem could happen if this occurs in brain cells and may cause DEATH.

As we mentioned above, when you drink too much water "cells starts to swell". When brain cells swell it raises the pressure inside the skull which lead to water poisoning symptoms.
Mild cases:
- Headache
- Nausea
- Vomiting
Moderate cases:
- Double vision
- Drowsiness
- Confusion
- Increase blood pressure
- Cramps and muscle weakness
- Difficulty in breathing
Severe cases: (1)
- Seizures
- Brain damage
- coma
- Death
Death from drinking WATER? Really?!

Actually that sounds pretty weird right?! Well, it's very difficult to reach that stage of poisoning. However, few cases have been reported due to this condition like in soldiers. (3,4)
One report illustrated how three soldiers died from excess water consumption "Hyponatremia" They drank 2.5-5.6 gallons (10-20 liters) in just few hours. (5)
It's very common to face water intoxication in endurance athletes like marathon runners. They drink too much water to avoid dehydration. Therefor, hyponatremia often occurs in the event itself. (6)
In another case after one major sport event, one marathon runner suffered from hyponatremia where his sodium levels were less than 130 mmol/L. He died from accumulation of cerebrospinal fluid and Brain herniation. (7)
Schizophrenic patients could suffer also from hyponatremia due to too much water consumption. One study showed that 5 out of 27 schizophrenic patients died from water intoxication. (8,9)
How much should you really drink?
When you get thirsty, you simply drink water right? (obviously!) but you know what! it's more than that. Your kidney can eliminate 5.3-7.4 gallons per day ( 20-28 liters) and can't get rid more than 27-33 ounces per hour ( 0.8-1 liters) (10,11)
So the bottom line here is that you can't drink more than 27-33 ounces per hour ( 0.8-1 liters) or it will cause you hyponatremia.
A 9 years old girl who drank almost a gallon of water in one to two hours developed hyponatremia and intoxication. (10)

To determine how much water you really need per day to prevent dehydration or intoxication. You just need to (Wait for it....) exactly, you just need to listen to your body. Yes that's it my friend, but you need to listen to your body carefully which means that whenever you feel thirsty just leave whatever you are doing and drink and if you don't feel thirsty then don't follow the over-hydration concept and that's when you drink too much water even if you aren't thirsty; to prevent getting thirsty later.
The institute of medicine (IOM) suggests that men should consider drinking about 125 ounces ( 3l7 liters) per day and 91 ounces (2.7 liters) per day for women. Watch out, this includes beverages and water not water only! (11)
You should also consider your weight, age, climate and physical activity level so that if you are an athlete, pregnant woman or old adult then you will need extra water each day.
At the end of the day, there is no specific number of how much water you should drink daily but just don't drink too much water okay?!
