How much water should you drink every day? Apparently, not as much as you’ve been told. No study has ever shown or claimed that we should really drink 8 glasses of water a day, which roughly equates to two litres, it is just one of those “everyone knows” that people religiously follow.
The popular myth originated from The regulation of the water content of the human organism, where the author measured his own urine and sweat output and determined he lost 3 percent of his body weight in water per day- which came out to be eight cups. Based on this, for a long time the water requirement guidelines were eight cups. However, this is not the case anymore except that most people still know the saying: eight glasses of water a day.
Real, or clinical dehydration, when your body has lost a significant amount of water because of illness, excessive exercise or sweating, or an inability to drink, is a serious but rare issue- which almost always has symptoms. In fact, people who drink a lot of water are the most dehydrated as explained below. Hyponatremia is a condition whereby you can get really sick by drinking too much water, and leads to all kinds of complications such as a coma, heart attack, seizures and enlarged liver.
When you drink too much plain water, your electrolytes no longer can balance the exchange of fluid inside and outside the cell. This causes parts of your cells to swell and others to dehydrate due to loss of salt.Also, realize what you input doesn’t equal what you output. If you drink a glass of water, you do not urinate a glass of water. You will urinate a glass full of urine, which is filled with electrolytes and other stuff. So urine is flushing out minerals.
Another popular myth is that 60% of the body is water, and so you should consume a lot of water. However, that a falsify, your body is all electrolyte fluids such as the blood, lymph and urine with minerals.
Moreover, water does not help you to lose weight as many people believe or would like to believe. This is because water is not fat-soluble and cannot flush fat. Also, water does not flush out toxins, as commonly believed, because like fats- toxins are not water-soluble but fat soluble.Last but not least, drinking a lot of water doesn’t help dry skin. Having dry skin, mouth, or joints is a deficiency of vitamin A. Oil and fat is what keeps the skin younger-looking, as opposed to drinking ounces of water.
Your body knows when it’s thirsty- we have 52 perceptions of perceiving whether we are thirsty, hungry, hot or cold- so it is advisable to drink water only when you feel thirsty. Some fruits and vegetables may also hydrate the body twice as effectively as a glass of water.
