Recently, more and more often we come across articles and notes about the need to drink a lot of water. Drinking regimen is essential and drinking water is vital.
What is the danger of a lack of fluid
There are many common opinions about how much water you need to drink every day. Experts say that the norm of drinking water per day for each person is individual and depends on the person's lifestyle, on his physical activity and, of course, metabolism. Among the decisive factors are also:
- human weight;
The average rate of fluid is from a liter to one and a half, according to scientists at Harvard. And it doesn't have to be pure water. It is believed that a person needs about 30 ml of water per kilogram of body weight. Moreover, drinking a large amount of water at a time is also harmful - you need to drink water in small portions throughout the day.
Lack of water is dangerous for our body. Dry skin, brittle hair and many other seemingly cosmetological problems "grow" precisely from the lack of water. We often confuse the feeling of hunger and thirst. That is why nutritionists advise drinking a glass of water if you feel like eating. Lack of water is a provocateur of eating something sweet. This is especially noticeable during training. If you are exercising, try to keep water close to you, but do not drink in large portions - literally one sip of water will be enough. Also note that a lack of water in the body significantly reduces the effectiveness of training.
Chronic fatigue can also result from a lack of fluid. The child is that if the body does not have enough fluid, the blood becomes thicker, the heartbeat slows down and blood flows to the brain more slowly. Another interesting fact is that a lack of water can lead to a bad mood.
Is it harmful to drink with food?
If you are a supporter of proper nutrition and take care of yourself, then you have probably read and heard that drinking with food and immediately after eating is harmful. This is because the liquid dilutes the gastric juice and the food is digested more slowly. In the long run, this can lead to digestive problems. For the same reason, drinking water (tea, coffee, juices) is not recommended immediately after meals.
However, recent research has shown that this is not the case. According to research by scientists at the University of Calgary, drinking in no way affects the acidity of gastric juice. Our body itself regulates acidity, and it rises even when we smell food or see delicious dishes. For a noticeable change in acidity, a person needs to drink a huge amount of water, which is impossible even physiologically - the capacity of the stomach is about one and a half liters.
Drinking water before meals or during meals even helps us to some extent - this way we eat less. The main thing is that it was just water, maximum - unsweetened weak tea. No sugary sodas, alcohol, or juice from the bags.
