When to Drink Water?
Recently, subject and sales of "water" H2O is getting popular in Japan. There are parlors and bars that offer to drink only WATER. Nowadays, water business is good in most countries. There are big malls where they offer free cold water to shoppers.
Most people say that they drink water when they feel that their throat is thirsty. However, our research group says that simply drinking when you are thirsty is insufficient in maintaining the body's moisture (fluid). On the other hand, too much drinking can cause "water intoxication" a.k.a. hyperhydration or water poisoning.
To get healthy, let us drink water at the right time and at the right quantity. But when and how?
Do you know that our body has a certain cell that keeps water in it? If we do not have such cell in the body, even teardrops won't come out from our eyes. What is that? Is it a new discovery? It was just found in 2003 by an American scientist.
The kidneys clean (filters) the blood with water, but don't you know that the quantity of water that passes the kidneys is about 150 liters in a day!? The average person has approximately 4 – 5 liters of water in the blood, and the kidney filters almost 99 % of it repeatedly. Excessive moisture or water is discharged as urine.
We tried to analyze the quantity of sweat and urine after exercise and quantity of water taken after being thirsty. The result – an average person lost 520 ml of sweat and urine while they drank only 150 – 200 ml of water. Yet, why many were satisfied with just less than a half of water intake compare to the 500 ml loss of water from the body?
It is probably psychological or some mechanical effects of the mouth that make us feel thirsty. It means that if you do something to your mouth, although you are losing moisture from the body due to sweat and urine, you may not feel thirsty at all. Bingo! We discovered that if you stimulate the mouth, a certain wave or signal will go to the brain, and you will not feel any thirst at all. Try it by yourself.
The thirst mechanism can be altered by "hallucination". That's what it means and it is really true.
The water you drink remains first in the stomach, and it slowly moves to the intestine and from the intestine to the blood. This process takes a little time to fill enough quantity of water in the blood, and your brain may still trigger thirst. During this process, you might drink too much water and may reach to a dangerous state called "water intoxication" that can lead people to death.
Actually, in order to avoid such dangerous stage, a sensor in the mouth and throat will tell your brain that water is present in the mouth, and will no longer trigger thirst. This is the thirst mechanism of the throat, which prevents you from drinking too much.
Therefore, by means of a certain kind of stimulation in the mouth, throat wave or signal can cheat the feeling of thirst. Yes, it is true and it is what we call "hallucination".
Let's chew a candy or gum, or pinch your lips several times, your thirst will disappear. It is just like hallucination in the brain, but only momentarily. Soon, you will feel thirsty until real water reaches your blood.
When the moisture of internal body becomes insufficient, viscosity of the blood becomes strong (sticky). And of course, there will be a danger of myocardial infarction and other blood-related death as well as brain damages or heatstroke.
We lose approximately 2.5 liters of water a day regardless of climate. Of course, during a very hot summer, you may lose more than 3 liters due to sweat.
Our meals in a day contain approximately 1 – 1.3 liters of water. Thus, it is necessary to drink some additional 1.5 liters of water to keep our body's moisture to a normal level.
It is recommended to drink about one glass of water every one hour during daytime and some cups of coffee, tea, or fruit juice during morning and evening. It is not recommended to drink too much water in a short period as the water you drink may just escape as urine. It is also recommended to carry a water bottle with you during daytime. In this way, your health condition will be improved dramatically.
We do not recommend drinking carbonated beverages because it contains sugar and it might make you fat. Coffee and tea contains caffeine, which increases number of urination and lose more water in the body. This is just the same to beer and wine. If you drink alcoholic beverages, you will lose more water in the body. Too much alcohol might lead to death, too.
Proper drinking of water makes you healthy and young.
INTERESTING WATER TRIVIA
Here's some miscellaneous trivia that you may not have known. Test your knowledge and share what you learn!
- Koala (well known as an icon of Australia) is an Aboriginal word meaning "no drink". It is because there's no one who saw Koalas drinking water. Such an idea is factually mistaken as Koalas do drink water, but only rarely, due to their diet consisting of eucalyptus leaves, which contain sufficient water.
- Another one is about Kangaroo. A common legend about the kangaroo's English name is that it came from the Aboriginal words for "I don't understand you." According to the books, Captain James Cook and his companion Sir Joseph Banks were exploring Australia when they happened upon the animal. They asked the natives what the creatures were called. The local responded "Kangaroo", meaning, "I don't understand you", which Cook took to be the name of the creature.
- The desert rat is another animal that get their liquid from the food they eat. Although they don't actually drink, they still need water from their food.
- Human blood is 83% water. Human bones are 25% water.
- Poor quality drinking water kills the equivalent of 20 jumbo jets filled with children every day.
