Heat waves and Consume water, milk and additional water in food during spring and summer

 Heat waves and Consume water, milk and additional water in food during spring and summer

The results of the investigations on the consumption of liquids in the summer and spring during 2017-2019 are given. Summer 2019 turned out to be the hottest season and with the most water demand where people consume the greatest amount of water with an initial contribution of liquids in water and milk of 1925 ml / day to which an additional supply of water must be added during that stage. 150 ml / day for water management and a gradual contribution of 100, 150 and 100 ml / day during 1.0-7.0 am to counteract the respective effect of heat waves, for a total contribution during the 2425 ml stage / day, in addition there is an additional contribution of the average water consumed in fruits and vegetables of 482 ml / day and an average contribution of water contained in other foods of 239 ml / day. In the spring of 2019 an additional supply of 100 ml / day was made for water management and 100 ml / day to counteract the effect of the heat wave with a total contribution during the stage of 2025 ml / day.  Juan G.R., Juan G.R. y Juan P. J.A. Heat waves and Consume water, milk and additional water in food during spring and summer. Water and Irrigation Vol.: 11, No. 1: 38-42, June 27, 2020. Spain.

The human body is made up largely of water the average constitutes 65% of body weight. This average value is calculated considering all ages and sexes, but it varies with age: in the elderly it is generally less, in babies it is around 80% of the weight, in men it is usually greater than in women. The kidneys contain approximately 83% water, the lungs 80%, the liver 74%, the brain 75%, the muscles 75%, the blood 80%, the skin 65% and the bones only below 15% according to anatomical and physiological studies of the Ministry of Health. The obese and overweight people are those who have a lower percentage of water in the body, due to a greater amount of adipose tissue that usually has less than 20% water, so these people can contain water in the body with values ​​less than 50%.

Water is a solvent for minerals, water-soluble vitamins and nutrients, thus it acts on different metabolic functions of the individual, transports oxygen to the cells and constitutes the main component in many fluids such as saliva and sweat. Water is a thermal buffer to regulate the internal temperature of the body. Through water, numerous waste substances and toxic substances are eliminated through urine and sweat.

The World Health Organization recommends that one liter be taken daily for every 35 kilos of weight. Age, weather or sports practice can raise that amount. On the other hand there is whom recommend drinking at least 2 liters of water a day to ensure an adequate water supply, nor is it recommended to drink more water than necessary.

According to the European Food Safety Commission (EFSA), the recommended consumption of liquids from the age of 14 should be 2.5 liters a day for men due to a higher demand for calories and 2 liters / day in the case of women. According to a survey in the case of adult men, 33 percent stay below 2.5 liters / day and in the case of women, 21 percent do not consume the 2 liters / day indicated, according to the University Institute of Biomedical and Health Research.

The results were taken from the investigations carried out by Juan and Collaborators on the flow of urine and its relationship with the climatic factors that were carried out in Alicante for 3 years, 2017-2019 for the different times of the year, which consider winter, spring, summer and autumn, the body’s water deficit was studied for values ​​of 1.9 to 2.3 ml / min for the flow of urine and for a normal flow of urine with values ​​greater than 2.9 ml / min according to the investigations carried out.

Summer is the season of the year with the greatest climatic demand, which is why it is the period when people consume the most water. In the summer of 2017, the initial contribution of liquids in water and milk was 1925 ml / day, to which must be added during this stage an additional supply of water of 150 ml / day for water management and 200 ml / day to counteract the effect of heat waves, with a total contribution during the stage of 2275 ml / day.

In the summer of 2018 the initial contribution of liquids in water and milk was 1925 ml / day, to which must be added during this stage an additional supply of water of 150 ml / day for water management and a gradual contribution of 200 ml / day and 100 ml / day to counteract the respective effect of heat waves, with a total contribution of 2375 ml / day during the stage. The summer of 2019 behaved hotter than the others, with an initial contribution of liquids in water and milk of 1925 ml / day to which must be added during that stage an additional supply of water of 150 ml / day for water management. and a gradual contribution of 100, 150 and 100 ml / day during 1.0-7.0 am to counteract the respective effect of heat waves, with a total contribution during the stage of 2425 ml / day. The results are in accordance with the recommendations of the European Commission for Food Safety.

During the spring of 2017 and 2018 there was no heat wave, so no additional contributions were made to counteract the effect of the heat, only an additional supply of 100 ml / day was made for water management, for a contribution of liquids during the 1925 ml / day stage. In the spring of 2019 an additional supply of 100 ml / day was made for water management and 100 ml / day to counteract the effect of the heat wave with a total contribution during the stage of 2025 ml / day and he agrees with that recommended by the WHO to provide 1 liter of water per 35 kg of weight.

The total contribution of liquids during the winter was 1935 ml / day and in the autumn of 1825 ml / day during the stage and constitute the seasons of the year with the lowest water demand, as a consequence of being two stations where the trend of lows predominates temperatures.  During 2017, the average contribution of water consumed in fruits and vegetables was: 451 ml / day in the spring and 457 ml / day in the summer. In 2018, the average contribution of water consumed in fruits and vegetables was: 490 ml / day in the spring and 498 ml / day in the summer. In 2019 the average contribution of water consumed in fruits and vegetables was: 466 ml / day in the spring and 482 ml / day in the summer.

During 2017, the average contribution of water consumed in other foods was: 221 ml / day in the spring and 232 ml / day in the summer. In 2018, the average contribution of water consumed in other foods was: 238 ml / day in the spring and 236 ml / day in the summer. In 2019, the average contribution of water contained in other foods was: 225 ml / day in the spring and 239 ml / day in the summer. The results were calculated taking into consideration the nutritional balance investigations carried out by Juan, for 4 years in the period 2013 and 2016 on the food eaten daily, using for this the balance method that uses the amounts ingested in: calories, proteins , total fats, saturated fats, carbohydrates, fibers, sodium, cholesterol and the contribution of water, nutrients and vitamins. It is concluded that with an adequate diet, the amount of food ingested in: meat and fish, carbohydrates, fibers, fruits, vegetables and others is distributed in a balanced way, a balanced management of food, nutrients and cost of food eaten, improves the health and quality of life of people.
