Nowadays, we hear folks mention the 8×8 rule more and more often. We do not solely hear it on TV or at the hospital, but additionally in the park, at the supermarket or even at the petrol station. Everyone looks to understand that drinking eight 8-ounce glasses per day could be a necessity if you would like to stay healthy.
But is it really so? Do our bodies really want that certain amount of water everyday? Or it’s just an invention whose purpose is to form us more careful to what we drink?
Well, scientists have finally come to a steadier conclusion: It does not matter however a lot of water you drink daily, as long as your body is properly hydrated and you do not feel the need to drink a lot of.
And after all, there’s no reason to question this, we all understand that the human body is capable to make us aware of our deficiencies. Don’t we feel the want to eat when our stomach is empty? Or do not we begin shivering when we’re cold? it is the same with water, we feel thirsty each time our body needs more liquids.
There’s no purpose filling up our body with water if there isn’t any want for it. There’s really a huge reason why we should not.
It’s a known fact that too little water will result in dehydration, and dehydration can easily kill you. But have you ever thought that an excessive amount of water may also have the very same effect?
In everyone’s body, there is a certain balance between the electrolytes (the minerals from the blood along with the fluid that carries the electrical charge) and water. Once this balance is destroyed, that person’s life may be in a very real danger.
Physicians call this health issue “hyponatremia”, but it is wide known as “water poisoning”. It may sound funny, but it is a very severe condition that, if not treated properly and rapidly, can lead to renal failure and afterwards, death.
How will this happen? Well, once the quantity of water from our body becomes a lot of higher than normal, the quantity of electrolytes can become too low for it, therefore an imbalance between these two would be unavoidable.
And once that imbalance appears, the person will begin to experience muscular cramps, dizziness, nausea and even convulsions. If these aren’t treated, they can rapidly lead to death.
Therefore, is water poisoning one thing we will usually deal with? Is it something we should always try and avoid the maximum amount as we can?
Well, fortunately for us, it’s pretty hard to play tricks on a combine of healthy kidneys, even by mistake.
This means that water intoxications are not as common in average individuals as they’re in professional athletes. The latter are really best-known for consuming a much higher amount of water, but for good reasons, right?
Well, the results of a 2005 study published in New England Journal of medicine claim that almost 1/6 of the 2002 boston Marathon participants have experienced a certain level of hyponatremia.
Another study, published in the 2006 British Journal of Sports Magazine, states that physical exercises are ofttimes associated with hyponatremia because of the excessive water consumption.
In that article, Timothy Noakes and Benjamin Speedy, two sports medicine doctors, claim the biomedical community is in a method of admitting the risks of the over-hydration in professional athletes.
However, these examples aren’t one thing we should worry about an excessive amount of, as they are pretty rare cases in average people. The most important issue is to drink a correct amount of water once physical exertion or effort, without exaggerating.
So, now you are probably wondering “Okay, too much water is not good at all?”, but will drinking too much water really kill you?
Yes, it can, in theory. But simply like I said before, it’s not really the case to worry, because you could not normally drink so much water that would lead to water intoxication. Your body would show you clear signs and would make you stop.
However, be careful with how much water you consume after a high effort and ensure you do not drink a much higher quantity than you’re feeling your body needs. As long as you respect this, you will never have to raise yourself if drinking an excessive amount of water will kill you.
