Whatever stated regarding water-intake is not unfair. Conventionally, healthy active standard adult female/male requires to take those amount of water per day respectively. In case of any disease or ailment and spacial environment - there are customized advice too.

we all need water there’s no life without water since the water have three quarters of the earth also give us energy and make our skin better

Dear Nagham Yahya ,

Yes. Water is important to our life, even weights more than our foods. I ask this question is to remind people to think. Not all of what we learned before our "right" such as atom was the smallest particle in the world, before the old stone era, there had no civilization as advanced as we do, etc. Now, they should be revised.

It's the same thing that many medical education should be reviewed. Otherwise, many diseases are caused from wrong concepts!

Last December, due to the wrong concept of drinking 8 cups water per day, I was forced to drink too much water for near a month. Later, I told one of my cousins that without doing so, a family's female owner did not allow me to sleep and she did not go to bed after 11:00 P.M. just waiting me to drink water. Until I drink a cup of water, she did not come to my room to force me drink water.

Another family, my mother's best friend kept correcting my "concept" whole day long about drinking more water. For two more days, she could not stop to let me drink water. Otherwise, she did not allow me to make her healthier. We also could not chat any other stuffs.

For their health, I scarified myself and abused my body by putting too much water into my body. Is it funny? That I ought to against my body needs and I was healthy survived 67 years without drink so much water as the textbook taught me.

My body knows how to better absorb nutrition from foods. So, I eat less and can do more than regular people. My body also knows how to recycle water. So, besides water from the foods, I am hardly to drink water.

Besides that, my tiredness to treat patients and kept all of my routing jobs. I got eczema after one month visited friends and relatives. This event, induced me to wake up people from now on.

I will correct people's wrong medical concepts gradually by posting more questions or give more medical facts about the real health.

Best Regards,

Frieda

Dear Md Rabiul Alam

According to your answers, there are many questions that we can discuss. Before we go far, may I ask you two questions:

Best Regards,

Frieda

Everyone needs at least 1 liter of water to balance the body. So the body stays healthy in all daily activities.

Dear Yunus Laukapitang

Thanks for your comment. Could you give me a reason and support? Thanks.

Frieda

How do you know how much water is proper to take? Have you ever thought it's the same question to ask what is the size of a dress to give a person to wear?

Of course, you will say each one has a different size to wear. It should be the same as to how much water a person should drink. It's is depends on each one's health and his body needs. Such as sweats out, sit in an sir condition room without sweat, take diuretic drug, a person lives in south pole or equator, etc. Can set a "standard water to drink" right?

Do you know there are so many diseases are due to extra water inside the body? Funny is that those patients also keep "drinking water" by learned before?

Have you ever asked a patient who takes a diuretic drug, do you still retain water? He will tell you "yes"! It's due to he feels, the more thirst. If so, what will you think?

Should we keep the same knowledge level from elementary to adult, to elderly to even lay on bed and needs a 24-hour caregiver? That a person should drink "8 cups water per day?" Do you think that we need to update the "standard" that is not objective nor scientific? Or, there are more researches need to do in order to update this "king does not wear clothes." story?

In relation to the minimum intake of 8 glasses of water per day, I personally believe that this is a cultural knowledge. A custom that with the coming and going of time has become a truth. Water forms a high percentage of the body's cells. It is necessary for all the metabolic functions of the organism, during the whole life of the individual.

I do not know if there are controlled studies that, through empirical investigations, give this knowledge as valid. However, it is necessary to maintain metabolic functions in a balanced state.

I have observed that in tropical countries, where temperatures reach very high values, practically all year round, the need to consume water is more than urgent, mainly on summer days (almost 365 days a year), including consuming one greater amount of water.

However, I have also experienced that in countries with a regularly cold climate, or in winter, consumption and water loss is lower. I suppose that this is because in them, the energetic metabolism generates less heat production, heat that must be damped with the adequate supply of water, which we owe when the organism fires its alarms.

Water, like blood, is life, and although "what overflows does not harm", we must be cautious because in excess it can harm us.

In places affected by the prevalence of infectious diseases that lead to the loss of body water, life is at risk, so the urgent contribution of this precious fluid is necessary, along with other chemical elements that help reduce morbidity. and mortality from such diseases.

I never questioned, but i have heard it over and over. Personally i hardly take water but all is well.

Dear Hector JOSE Ruiz-Camacho ,

Thanks sharing your experience. Let use a scientific reasoning approach: In a specific environment, our body has its optimum water quantity. Within this water quantity people are healthy.

Under this premise, if there is water loss, i.e. water expelling outside the body, the same or similar amount water should be compensated back. It's either from drinks or foods. Does it sound right to you and to every one?

If people in different hot and cold environments to loss different water amount, in different diets to intake different amount of water, in different health situations of abnormal sweating a lot or no sweat at all, scientifically speaking, besides regular intake foods, drink 8 cups water for everyone is "not scientific", "does not make sense" and "not right."

When we were kids, we ran, activated a lot to consume more water inside our body. After adults, most of us sit in the front of a computer whole day long, without exercises, without sweats, no abnormal urination, diarrhea, vomiting to lose water. Why we all need 8 cups water?

If health education says to drink 8 cups water to wash body is the main point, besides my discussion on https://www.researchgate.net/post/Do_you_think_that_drinking_water_can_wash_out_the_bodys_waste_and_or_toxins#view=5c944e2b979fdc77dd632710, please think this way:

So, to drink 8 cups water is not right. If it's not right, it will cause many diseases. I will discuss it later.

Best Regards,

Frieda

Dear Catherine Gakii Murungi

Lucky that you are not in the medical field. Otherwise, I will urge you to question about it. In many fields, all people said does not mean it is right.

Do you know our body can recycle the water? Even for spirit cultivating people, can absorb water and nutrient from the air? Reabsorb more nutrients from intestines if there is no food intake?

I put this question, is due to I am tired to treat patients whose health problems are caused by improper intake too much water under this "8 cups water".

Best Regards,

Frieda

While I am not a medical doctor (I am an academic one), I have to base my answer from my experiences in the military and police. If someone is dehydrated they do not preform as well at critical tasks. They can even make bad decisions at critical moments. In extreme cases it can cause injury or death. Coffee or soda does not do the same thing to the body. In fact it can accelerate the process of dehydration in extreme cold or heat. We were always trained that any excess hydration would be urinated away.

Dear Gregg W. Etter ,

Thanks for your comment. You supplied good health knowledge for dehydration that the body cannot perform the normal metabolism and activities.

Yes, people under dehydration can cause many health issues to death. However, usually except kids who are too young or shortage of water to drink, people will look for water to drink.

Coffee or soda supply tastier than water plus advertisement added values. In fact, they all can cause more health issues than water and supply fewer health benefits than water.

In the western medicine, people are easy to see the severity of shortage water supply, but neglect the oversupply of the water caused health issues. The extra water can be urine out is only for a healthy person. Please read my comment about the extra water caused health issues at https://www.researchgate.net/post/Do_you_think_that_drinking_water_can_wash_out_the_bodys_waste_and_or_toxins .

Relatively a policy or a military person has a better health than a general public due to the health screen and physical training.

In Chines medicine and Chinese culture, there is always a moderate level, i.e. a maximum and a minimum level regulate us to stay between the two levels to not cause any problems. Any hypo or hyper water supply will cause troubles.

On the other hand, in TCM, we have more alert to our body's needs instead of listening to the school's "western education".

Frieda Mah Thank you for your question. The amount of water we should drink daily varies depending on age, gender, physical activities, the temperature of the environment. Also, people who have fever, dehydration, or flying, having vomiting or loose bowel motions may need to drink more water to compensate for the loss. When there is vomiting and or diarrhoea, they may need to have some salts with the water (rehydration fluid). State of health could affect the amount of water we need, in some diseases like heart failure or chronic liver or renal problems, the amount of water intake may need to calculate according to the severity of the disease. Therefore, there is no single advice that matches everyone. However, for healthy male adults, the recommended amount is 3.7 Litre fluids, and for healthy adult women, the amount is 2.7 Litre fluids.

Dear Samy Azer ,

Thanks for your detailed comment.

Drinking water depends on each individual's needs. But, I met many people who follow drinking 8 cups of water per day. They forced me to drink water. It was a very painful experience. If I do not drink water, they think that I against basic medical knowledge. I do hope the textbook should get revised.

In TCM, intake water in foods or drinks all can be recycled in our body. So, TCM does not give any reference amount. Meanwhile, in a TCM clinic, we always ask the patient's feelings to let patients be more alert to their body needs.

Best Regards,

Frieda

Thank you Frieda, please read my last 2-3 lines in my previous response. For a healthy adult male, 3.7 Litres of fluids per day, and for a healthy adult woman, 2.7 Litres of fluids daily. I want you to do a practical exercise. Get a 1.5 Litre bottle of water from the market and measure how many cups of water will this be? The trouble in using the "cups" in your question, there are several sizes of cups, and we cannot say that all cups are one-size. The cups could be 30 ml, 100 ml, 150 ml, or 250 ml.

Now the answer: a bottle of water of 1.5 Litre capacity is (=6 cups of 250 ml-standardised old water cups). This means the 8 cups you mentioned are the minimum thing to drink if you are healthy (8 cups here equal 2 litres). Now when we say fluids we mean other fluids you may drink as well such as tea, coffee, lemonade and liquids in cooked food etc. That is why 8 cups is the minimum so long as you are healthy not having heart failure or renal or liver failure. I hope this answers your question.

Dear Samy Azer ,

Thanks for your explanation. You might surprise that besides regular meals, I almost do not drink any liquid. My meals do not cover soup most time. I almost do not eat many fruits: 1-2 oranges per day is enough. I feel fine.

Frieda

some articles suggest it is dependent on weight...

• Take your weight (in pounds) and divide that by 2.2.
• Multiply that number depending on your age: If you're younger than 30, multiply by 40. ...
• Divide that sum by 28.3.
• Your total is how many ounces of water you should drink each day.

As a young man, I thought I was immortal. The army and 30 years in law enforcement cured me of that silly notion. However, if you do not regularly take care of your body and that includes drinking the right amount of water, it will catch up with you in old age. Now that I am old, I regret smoking. I am told by my medical doctor that if you do not drink enough water eventually you will have kidney problems. You begin to notice these things when they begin to make you take pills because you did not pay attention when you were told the first time.
