How much water should a person drink each day? The role of water in our life

The theme that the health, beauty and harmony of a person largely depends on how much pure water it consumes, rises regularly. Especially it is popular among slimming. There is also the opposite opinion: excess fluid provokes swelling, creates an additional burden on the kidneys and heart. So how much water per day should a person drink and how to calculate the daily rate individually for each person? We will try to answer these questions.

Norm for an adult

First, each person is approximately 70% water. Secondly, a day we lose quite a lot of fluid with urine, feces, sweat. Accordingly, the body has a regular need for normalization, restoration of water balance. Therefore, scientists recommend drinking at least 8 glasses of clean water daily, without taking into account soups, broths, juices, tea and other liquid.

There is another assumption. A pier, the person should drink so much water that for one eaten calorie it was necessary on 1 ml of a pure liquid. But later the theory changed. And according to its new variant, along with the usual drinking water, you can replenish the liquid in the body with any drinks and food that contain it. It's about the first dishes, compotes, kissels and so on. Actually, it is still difficult to understand how much water a person should drink per day, because the opinions of doctors and nutritionists on this issue diverge.

Modern calculations of the water norm depending on the weight

The opinion that an individual is sufficient to consume 2 liters of water per day is recognized as erroneous. Today, scientists were able to calculate as accurately as possible how many people should drink water per day. The table below will help you calculate the volume of fluid, depending on the weight.

This table shows the norm of water without taking into account other liquids: tea, coffee, juices, etc. Also, according to studies, experts recommend the bulk of consumption in the morning. At the same time before going to bed, the amount of water drunk should be minimal. So you can avoid unwanted edema. Drinking water is advisable before meals, while drinking a lunch is not recommended, as well as consuming liquid during meals. But quenching thirst without limits is recommended during intensive training.

Why is it important to drink a lot?

After determining how many glasses of water a day a grown man should drink, one must understand the importance of this. There are several reasons to strictly adhere to the rule:

• Water helps to lose weight, because it suppresses the appetite. When a person experiences a feeling of hunger, she helps him to cope. In addition, the water does not contain calories.
• One who drinks a sufficient amount of fluid, reduces the risk of heart and vascular disease.
• Water gives a charge of energy, suppresses fatigue and increases overall performance.
• Lack of fluid can provoke headaches.
• Water takes a direct part in the digestion process. You can avoid many troubles associated with the gastrointestinal tract.
• Together with the liquid from the body are released harmful substances, slags and toxins.

And this is not all the reasons why you need to drink plenty of water. Remember that it is also a source of health and beauty. It depends not only on the internal physical state, but also on the appearance. Especially positively, the liquid affects the skin.

What kind of water should I drink?

Depending on how much water a person should drink per day, it is also important to know that the remaining fluids are considered unreasonable. Because any other drink - milk, juice, alcohol or coffee - contains a certain amount of calories. Therefore, they can, rather, equate to nutrition, rather than to drink. If there is a possibility, then it is better to refuse the maximum from the harmful liquid. For example, from soda, packaged juices, alcohol. Replace them with pure mineral still water. Because many drinks that we use to quench thirst, on the contrary, provoke it. Especially alcohol. It can lead to dehydration, if you use it in the heat, when thirst is tormented.

Some of us find it difficult to restore the water balance, because it is impossible to force ourselves to drink when you do not want to. In this case, it is better to limit the consumption of other liquid. For example, remove the soup from the diet. And replace it with a glass of clean water. Remember: the tap water will not be of use, because it contains too many impurities that are harmful to health. To drink any non-carbonated mineral water. In extreme cases, boiled or carefully filtered running water.
