LIFE Water and Health

Many people drink water often to be healthy. There are many waters that are good, such as deep ocean water from the clean deep sea, hot spring water and glacial water in the Alps. Drinking lots of water helps prevent chronic diseases and treats all kinds of diseases. Should I believe?

1. The function of water
Other than urolithiasis, there is a claim that drinking water can prevent cancer, cardiovascular disease, digestive problems, and allergic diseases because there is no disease that can be treated with water. Experts say, "This is an exaggerated claim, and water doesn't prevent disease." Except for urolithiasis, no water has a direct preventive or therapeutic effect. However, if you drink enough water to maintain the amount of moisture in the human body cells will increase cell resistance. This suppresses the invasion of various bacteria and viruses, and facilitates the discharge of harmful substances in the body.

Helping metabolism is the key function of water
The importance of water is more fundamental than the suppression of individual diseases. In the process of being absorbed by the body through the mouth, throat, esophagus, stomach, small intestine, and large intestine, water facilitates the function of each organ. It is to perform the core function of metabolism by rotating the whole body.

Green tea, coffee, beer instead of water
Caffeine drinks, such as coffee, tea, and green tea, have the opposite effect of draining your body of water. Caffeine promotes diuretic activity and releases water from your body. Coffee releases twice as much water and tea releases about 1.5 times as much water. Sugary drinks, such as juices and soda, can also cause dehydration. Drinking sweetened beverages increases the osmotic pressure in the body, which requires more water. Beer also has more water that drains into the urine than it drank.

mouth
As the water drips down your throat, it attracts microorganisms or bacteria from your mouth. Microorganisms and bacteria that have been swept away in water are harmless to humans because most of them get killed by stomach acid.

Neck, esophagus
The water soaks the vocal cords and makes a good voice, and moisturizes the esophageal mucosa to help peristalsis. If you have reflux and you drink a little water, your stomach acid is washed away. At this time, drink lukewarm water similar to the acid temperature.

top
Dilute the gastric juice to some extent. However, since water does not neutralize stomach acid, the stomach that is over-acidic does not sink in water. Damage to the gastrointestinal mucosa is a bit of help in the bitterness.

Major, large intestine
80% of the water drank is absorbed by the small intestine and travels through the veins into the blood. The rest goes down to the large intestine to dilute the stool, and some are absorbed through the large intestine veins. Drinking less water reduces the water coming to the large intestine, causing constipation.

Blood, skin, respiratory system
Blood supplies systemic cells with nutrients and fluids, and then returns with the cell's waste products. The returned water flows to the kidneys and becomes urine. The water that reaches the skin cells is released into the sweat along with the waste. The water that goes to the respiratory tract “cleans” the dust in the bronchus. Drinking water often to moisten the bronchial tubes will help clean them, even if you breathe. Bronchial moisture is evaporated with water vapor.

2. How much should I drink?

If you lose a lot of weight, you should drink more.
Replenish your body with water as much as your daily water output. The average body weight of a day's body weight is 3.1 liters. 1.6L in urine and 0.5L of sweat, breathing and skin. Usually adults consume 1 to 1.5 liters of water from the food they eat. Recycling (water generated during cell metabolism) Since the water is about 0.1L, drink the remaining 1.4 to 2L of water to replenish.
If you are losing a lot of weight, you may need to drink more than this. The heavier the weight, the greater the need for water. Multiply your weight by 30-33 to get your approximate water requirement (L). Adults weighing 70kg should drink 2.1 to 2.3L. You should also drink more when the weather is hot or when you are sweating enough to get your top wet. Less urine and darker colors are a sign that your body is dehydrated.

I like to drink water every hour
Drink water once every hour. In particular, older people have a lower rate of resorption of water in the kidneys, and the thirst in the hypothalamus of the brain ages and the body does not feel thirsty even if the body lacks water. It is a good reason to consciously drink water every hour. The water should not be swollen, but it is better to drink one or two sips and chew it.

Excessive causes abnormal symptoms
People with normal kidney function are mostly excreted through their urine after about 2 hours even if they drink a lot of water. Drinking a lot of water means nothing more. The important thing is the speed of drinking water. Drinking too much water at once can lead to hyponatremia, which can lead to headache, nausea, dizziness, and muscle spasms. Even if you are thirsty, do not drink more than 0.5L of water at once.

It's not good to drink a lot unconditionally
Drinking lots of water unconditionally doesn't benefit your health. You just need to drink as much as you need to maintain your metabolism, which supplies your cells with moisture, nutrients, and waste products. Healthy people have enough metabolism to drink only when they're thirsty. Water requirements are not constant. It depends on your weight, activity and weather. More than 60 years ago, in 1945, the United States claimed that drinking 8 glasses of water with 8 ounces (227 mL) of glass every day is good for your health (8 × 8 theory). Concluded that it is not particularly helpful.

I can't buy even if I drink a lot of water
It is not true that 'you can gain weight by drinking only water'. Water has no calories at 0kcal. You will gain weight temporarily, but if your heart and kidneys are normal, you will return to your normal weight because of diuresis. However, if you have a heart or kidney abnormality, your body can accumulate moisture and gain weight. Healthy people drink water and appear fat because of edema.

3. water and disease
Kim, 47, who has mild heart failure, said that she usually drinks "a lot of water" during outpatient care, but she was pointed out that "complications can occur." Mr. Kim told a friend with angina that his doctor told him to drink a lot of water. But the doctor said, "Heart disease is one that requires a lot of water and one that should not." There are two diseases that encourage fluid intake and others that limit it. If you need to promote circulation and waste discharge, you need water. If you have poor circulation and drainage, keep water away. If you need to drink less water, drink only the amount suggested by your doctor and reduce your salt intake.

A disease that requires less drinking

1 severe hypothyroidism
Drinking a lot of water can't drain well, resulting in hyponatremia. If you have severe hyponatremia, you should get a sodium transfusion. If not severe, limit your water to less than 1 liter per day.

2 cirrhosis
Decreased liver function does not produce albumin. Lower levels of albumin in the blood increase the water content in the blood because the water is not distributed to each organ and remains in the blood. Increased water can flow into the abdominal cavity, causing the stomach to get vengeful.

3 kidney failure
Only drink thirst when your doctor is thirsty. Stage 5 dialysis patients lose their chance of producing albumin as the protein is released through dialysis. The water then flows into the abdominal cavity rather than distributed to each organ.

4 heart failure
If you have heart failure, your heart will fail and you will not get enough blood out of your heart. Therefore, water should be drunk within 1 liter per day. If you drink more than that blood is not properly circulated, stagnating in the blood vessels. When blood pressure increases due to increased blood volume, water can flow into the low-pressure lungs and brain, causing edema. Excessive water also causes hyponatremia.

5 Adrenal Insufficiency
The oversignal hormone, aldosterone, is produced in excess, which prevents the smooth discharge of water and salt. Therefore, much fluid intake causes systemic edema.

A disease that requires drinking plenty of water

1 pneumonia, bronchitis
Respiratory diseases, such as pneumonia and bronchitis, increase in heat and respiration, which increases the release of water through the skin and respiratory system. Drink lukewarm water a little often to keep your respiratory system dry.

2 inflammatory urinary diseases
If you have urinary tract infections, cystitis, or prostatitis, your urine will be too hydrated to release the irritant into your urine. If waste is not discharged and concentrated, it can turn into urinary stones. You should drink at least 500 mL more than your daily amount of urine.

3 diabetes
Diabetics who do not have complications of renal failure should often drink water to suppress blood sugar buildup. In particular, elderly diabetics who are not thirsty should consciously drink water every two hours, even if they are not thirsty.

4 hypertension, angina
Lack of moisture in the blood increases blood viscosity and slows blood flow. In this case, blood clots or fats build up on the walls of blood vessels, so it is better to drink 1.5 ~ 2L of water a day. Drinking enough water from the stage of dyslipidemia will help to prevent progression to angina. However, salinity should be thoroughly limited to less than 5 ~ 6g per day.

Drink water to stop summer cold
Drinking enough water will help prevent colds in the summer. Water keeps the respiratory mucosa moist and increases the activity of the bronchial and lung cilia, preventing viruses and bacteria from entering the respiratory tract.

4. You should drink water when you're not thirsty.
During exercise, you may already be dehydrated, even if you are not thirsty. Unknowingly, the water in your body is released as sweat, but you may not feel thirsty at this time. Therefore, whether you are thirsty or not, drink water regularly. Before exercise, you should drink water to prevent sweating. You should drink 5 to 7 mL of water per kilogram of body weight about two hours before exercise. Cold water absorbs faster than warm water, so it is good to drink cool water at 15 ~ 21 ℃. During the exercise, the electrolyte escapes through sweat, so drink a sports drink containing sodium and potassium instead of water. The amount of sweat varies from person to person, usually about two to three sips every 15 minutes. At the end of your workout, you should compare your weight before and after your workout. If you are losing 500g, you can drink about 750mL.

5. Number of functions, is it really good?
Pure water is a function water that adds ingredients that are not originally present or changes the properties of water. Although there are various functional water, experts say that there is no significant difference from ordinary water medically. 'Good water' is clean water without harmful substances such as pathogens that are harmful to the human body, and has weak alkaline (PH 7.5) that increases digestion or absorption of food.

Hydrogen water
It is claimed that drinking hydrogen water (dissolved water) can eliminate free radicals. But you don't need to drink it to get rid of free radicals. This is because free radicals must be moderately physiological in the body and the immune function is increased. Cho Byong-ryong, a professor of family medicine at Seoul National University Hospital, said, “You don't have to drink hydrogen water because you can maintain an adequate amount of free radicals by just exercising, smoking, and eating vegetables.”

Deep ocean water
It is a water rich in minerals, which is sprayed from the deep sea without sunlight and then dissolved in salt and other substances. Park Hyun-a, a professor of family medicine at Seoul Paik Hospital, said, “If mineral consumption is the purpose, there is no need to drink deep sea water. "Eat food is enough."

sparkling water
It is water that dissolved carbon dioxide. There are some claims that drinking carbonated water is helpful for constipation and diet, but Professor Park Hyun-a said, "It is not sufficiently medically proven."

Alkaline water
Alkaline water. Alkali ionized water, alkaline reduced water, alkaline bridged water, and the like are basically similar. One of the most well-known benefits of alkaline water is that it removes free radicals in the body to prevent aging and cure diseases. Professor Go-woon Kim said, "We can not expect alkaline water to be effective in suppressing aging of the body or treating diseases." Alkaline ionized water generator, however, has been approved by the Ministry of Food and Drug Safety as a medical device that is effective in improving symptoms such as indigestion, excessive stomach acid, chronic diarrhea and abnormal intestinal fermentation.

Oxygen water
Contains 10-15 times more oxygen than regular water. Some people say that oxygen water "becomes faster in the body than when you inhale oxygen in the air," but this is not true because the water passes through the stomach and becomes blood. However, by increasing the oxygen supply of cells in the body is effective to increase the body's physiological function. Professor Kang Go-Kyung of Wellness Center Kang Kang Kyung Hee Hospital said, “When you boil water, oxygen flows away and you just drink it. That's right. ”
