Have you ever wondered how many liters of water should we drink daily? To answer this question, it is necessary to assess the health, age and sex of each person.The water is a substance essential to our survival, working in various chemical reactions and physiological processes. Due to our inability to store this substance and its constant elimination by the body , we must always keep our body hydrated by drinking water.
There is much doubt, however, about the ideal amount to be ingested by each person. According to the Ministry of Health, it is recommended that at least two liters of water be ingested , preferably between meals. However, each person has a different metabolism and rhythm of life, which is therefore a recommendation of the minimum required for an adult.
Some authors recommend that several points be evaluated before establishing the ideal amount of water. Health problems, time of year, weight, height, physical activity, age and sex, for example, are some of the aspects to be analyzed before recommending how many liters of water are needed to meet a person’s needs.
There are several studies, however, that show ideal averages for each sex and age group . Babies up to six months, for example, should drink 0.7 liters of water, which comes from the mother’s milk. Men aged between 14 and 18 years old should drink 2.6 liters of water, while women of the same age need only 1.8 liters. Men over 19 should drink 2.2 liters of water, the same amount recommended for women in the same age group.
Some doctors and nutritionists also argue that, for adults, the ideal is that 35 ml of water be ingested per kilogram of mass. Therefore, for a 65 kg person, it is recommended to ingest 2275 ml of water. Observe the following formula:
Optimal amount of water = Weight X 35
It is worth mentioning that the recommendations for the amount of water to be ingested, which use weight, sex and age as criteria, do not take into account the context in which each person is inserted. On hot days, for example, sweat can cause a large loss of water, so greater replacement is necessary. The same is true for people who practice physical activity or who have gastrointestinal problems (vomiting and diarrhea ), in which the loss of water can be exaggerated.
People with heart and kidney disease should use water with greater caution, avoiding excessive intake. Excessive water in these cases can overload the kidneys and heart, aggravating the problem. Therefore, a frank conversation with the doctor is essential when there are health problems.
Analyzing the patient’s life and daily needs is essential for a correct recommendation of the amount of water to be ingested. It is important that there is a constant balance between what has been ingested and what has been lost for the body to function properly. Attention to excessive water loss and health problems can prevent the worsening of illnesses or the emergence of new problems.
