Bottled water companies these days in their advertisements claim that everybody should drink 7- 8 liters of water a day. Well, that’s all about selling their products and increasing their supply. It is a fact that life couldn’t exist without water, but in the right circumstance, water can be as dangerous as any poison. Your kidneys filter out excess waste and water from your bloodstream. But they can only process 1 liter of water an hour, and if you somehow managed to drink more than that without throwing up, you could run into trouble. Because you’re drinking faster than your kidneys can process it.
The excess ends up in your cells. Normally, your cells are surrounded by a carefully balanced solution of sodium and water, which flows in and out through tiny holes in the cellular membrane. So it keeps the sodium concentration, both in and out of the cell, balanced. But when you drink too much water, the sodium solution gets diluted. It’s not salty enough. So some of that excess water rushes into the cell to restore balance. And that causes it to swell up.
Doctors call this water intoxication, and it’s a big problem. Now, most of your cells can handle the swelling to a degree, since soft, flexible tissue like fat and muscle can stretch. But for the cells in your brain, it’s another story, because your skull isn’t stretchy. It’s bone. It’s hard, like a rock. So, as your brain swells, it builds up pressure in your head.
At first, you might experience headaches, confusion, or drowsiness, but as the pressure increases, you risk brain damage, coma, and even death. And it could all be over in less than 10 hours. A 64-year-old woman, for example, died the same evening after drinking between 30 to 40 glasses of water. People suffered vomiting and seizures after downing over two liters per hour.
Drink to your thirst – it’s the best indicator!
The average healthy adult needs somewhere around three to four liters of water a day. And since this can come from food and other drinks too, In fact, there is no set pattern that how much water one should consume in a day, so for each of us the best indicator of body requirement is when you feel thirsty drink water to an extent you are thirsty, do not intake water for the sake of some calculations that I have to complete 3 or 4 liters a day. So the only and the best intake of water is to drink when you’re thirsty and then stop.
