Water is seen as one of the first necessities of life. Many drinks are therefore considered to be very healthy. But how much water do we actually need? And can you drink too much?
"Water is essential to us as people. We have 60 to 70 percent of water. It is involved in all kinds of body processes such as breathing, the transpiration (and thus heat regulation), the stools, the blood pressure draining waste. In case of a shortage of water, there is a lower blood pressure. Lose weight by drinking water. The skin becomes more and more wrinkled at low blood pressure. However, it is not necessary to drink more water for a beautiful skin: water does not prevent skin aging. There are other factors involved. In principle, water has no influence on water. However, it can provide a full feeling, which makes you eat less. Also the role of water on the stool is not very direct. The most moisture we drink is absorbed by the intestine and excreted via the urine. The feces hold only a small part of the water. In case of a body shortage of water, moisture is extracted from the intestine or skin. This can lead to constipation. However, in normal drinking this is not the case. Drinking more than usual, therefore, does not affect the stool. "
"We need 2.8 liters of moisture per day. About 300 ml of it comes from the body itself and comes free in all kinds of body processes. In addition, 1 liter of moisture comes from our food. We have to get the last 1.5 liter with drink. It does not matter what, if it's moisture. The brains are very good when you need moisture, and you get thirsty. This stimulus is very sensitive, which means that a small change in the body soon leads to a thirsty feeling. In older people, the body thirst less well. Therefore, they should be more aware of drinking. These are the consequences of drinking too little water. A slight water shortage can lead to dizziness, headache, fatigue and reduced concentration. In case of a larger deficit, dehydration (dehydration) may occur: this may include fainting and respiratory problems. "
"You do not drink too much and a lot of drinks spread over the day cannot hurt. If you learn to drink a lot, your body will adapt to it. The urine is less concentrated and more plastic. You will also get thirst before, because your body adjusts to drinking more. However, it may be harmful if you drink a lot of water in a short period of time, for example two liters in half an hour. Your blood gets thin and the body cannot handle it. The concentration of salts in the blood becomes less and you have too much water in the body. There is then acute hyponatremia, also known as water poisoning. The body cells cannot handle this situation well and swell. If brain cells swell you can hit the coma. In hyponatremia it is important to reduce drinking water. "
"Normally, our body is very well able to maintain the water balance. Here, hormones, the thirst and the secretion of the kidneys play an important role. As mentioned, too much drinking can lead to an acute disturbance of water balance, but certain situations or conditions can also lead to chronic disturbance. Stressful situations or lung tumors, for example, affect the hormone vasopressin. This hormone retrieves water from the forurine. In cases of heart failure, cirrhosis of the liver and preeclampsia (pregnancy poisoning) there is a disturbed blood pressure. In either case, the body holds too much water: chronic hyponatremia. Actually I should drink more water - Useful tips. In case of vomiting and diarrhea, there may be a disturbed water balance due to disturbed blood pressure. "
"Water with minerals is better than just tap water. There are certainly differences between types of water. We never actually drink pure (distilled) water without salts, but usually mineral water or tap water. Mineral water is rainwater from the uninhabited land. The salts in which the water flows into the soil determines the taste of the water. No water can be added to mineral water. Tap water is purified surface water. The composition is laid down by law. In the Netherlands, the quality of tap water is quite good, maybe even one of the best in the world. For our health it does not matter what you drink: the kidneys filter the substances from the water they need. There is no evidence that mineral water is better than tap water or vice versa. However, the taste can be very different. "
