What Happens When You Drink Too Much Water?
We have established that you can drink a lot of water. So, what happens when you drink too much water? When you take more than what your body requires, the other nutrients in the body become diluted to a point that they can no longer carry out their functions as required.
To be more specific, it is a condition that occurs when the level of sodium (a salt and of course a nutrient) in your blood is abnormally low.
Have you heard of electrolytes? What are they? Electrolytes are salt ions that cells use to move fluids and nerve messages into and out of cells and throughout the body. Without electrolytes, your body can’t function. Sodium is an electrolyte and it helps regulate the amount of water that’s in and around your cells.
When you drink a lot of water or rather fluids, the sodium in your body becomes diluted. This state causes the water levels in your body to raise which means your cells will take up more water. It eventually leads to swelling of the cells.
Hypothetically, cells can swell to the point of bursting and can result to several health issues, from mild to severe or even death as you will learn shortly.
Can you die from drinking too much water?
Can drinking too much water kill you? YES! Excessive intake of water especially within a short period can lay you to rest forever. Water is life but if consumed inappropriately it can be a life-taker as well. Water intoxication can actually lead to death. You will shortly find out more about individuals who have died from water intoxication.
How does dying from drinking too much water happen?
The kidneys regulate the amount of water, salts and other solutes leaving your body by sieving blood through their numerous twisted tubules. When you drink too much water in a short span of time, the kidneys cannot flush it out fast enough and the blood gets diluted with lots of water. This causes an imbalance of salt (sodium) within and without your cells.
Do you remember osmosis from your biology classes? It is the movement of water across a semipermeable membrane from higher to lower concentration.
By osmosis, excess water leaves blood (where concentration is low) and enters the cells where concentration of salt and other dissolved substances is higher. For the cells to accommodate the excess water, they’ll be forced to swell like balloons.
Technically, swelling will require a flexible environment. Unfortunately, not all cells have flexible environment.
Cells in majority parts of your body are solidly placed in flexible tissues such as muscle and fat-which offer room for expanding or stretching.
In contrast to other cells in your body, brain cells (neurons) cannot stretch or expand because they are embedded in the skull which is boney and rigid. In fact, the neurons share space with blood and cerebrospinal fluid; a clear, colorless body fluid found in the brain and spinal cord.
So, when water levels in your body have gone up, the brain cells will take more than enough and this will lead to brain swelling, which ultimately leads to death…this is how you can die from drinking too much water.

How much is too much Water in One Hour/ a Day
Water is lost from your body through breath, sweating, bowel movements and urine. Because of these losses which of course are normal, you need to consume beverages and foods that contain water for the replenishment purposes. Your body needs water to function properly.
As mentioned earlier, the kidneys are the organs that monitor the amount of water and mineral in your system. Before even going to how much you need in an hour or a day, your kidneys must be functioning well.
Other than the kidneys there are other factors such as your general health can also influence how you will take.
If you are healthy and with no kidney issue, the scientific America states that your kidneys can filter about 800 to 1,000 mL or 0.21 to 0.26 gallons, or four cups of water every hour..
Well, you already that your kidneys can safely handle 4 cups in an hour. What about a day?
According to some experts, the amount of water you need depends on your size and weight, your activity level, the kind of food you take, gender and where you live.
The same experts recommend that on a daily basis, you should try to drink between half an ounce and an ounce of water for each pound you weigh. For instance, if you weigh 150 pounds, that would be 75 to 150 ounces of water per any given day.
If you’re living in a hot climate and exercising a lot, you are likely to be on the higher end of that range; if you’re in a cooler climate and mostly sedentary, you’d need less. If you take plenty of food that contain less fluids and more salts, proteins and fibre, you will need more.
According to the Institute of Medicine, men and women should take roughly 3 liters and 2.2 liters respectively.
You should also be aware that drinking 8 glasses of water per day is just but an old myth. There is no scientific evidence to back it up.

This amount is in a addition to what you get from food and fluids.
- Avoid water/fluid drinking contests.
- Always think before you take an action. Don’t just do it because others are doing it. Find supporting information or simply enquire from a certified doctor or professional.
