Urine flow and the influence of climatic factors in 2018

Juan G. R., Juan Prado J. A. and Juan G. R. Urine flow and the influence of climatic factors in 2018.

Water and Irrigation Vol.: 11, No. 1: 17-20, April 14, 2020, Spain.

The urine collected during Phase 1, from 1.0 to 10.0 AM of the 2018 investigations is 1354 ml / day / phase and represents 76.4% of all the 24-hour average urine that is 1773 ml / day, while the Urine during Phase 2, from 10.0 AM to 1.0 AM is 418 ml / day / phase, representing only 23.6% of the total. The contribution of water and milk plus the water contained in 24h in the ingested food, plus the additional contribution of water during the heat wave was 2583.9 ml / day for the annual average of the 4 times of the year. The annual average urine flow in F-1 was 3.0 ml / min and 0.42 ml / min in Phase 2. Climatic factors: temperature, relative humidity, barometric pressure and wind speed, generally act together on the behavior of urine flow, the most frequent being the combined action of 2 and 3 factors, which are influenced by the effect of climate change and global warming that cause them to be increasingly unstable and variable .

From the investigations 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 water deficit for values ​​of 1.9 to 2.3 ml / min for urine flow and for a normal flow of urine with values ​​greater than 2.9 ml / min, during Phase 1 of the investigations.

Climatic factors were taken from AEMET data sources at the Climatic station El Altet located about 10 km away from where the investigations were carried out, daily evaluating the behavior of urine and influencing climatic factors: temperature, barometric pressure, humidity relative and wind speed.

The urine collected during Phase 1, from 1.0 to 10.0 AM of the 2018 investigations is 1354.4 ml / day / phase and represents 76.4% of all the 24-hour average urine that is 1772.7 ml / day , while urine during Phase 2, from 10.0 AM to 1.0 AM is 418.3 ml / day / phase, representing only 23.6% of the total. The contribution of water and milk plus the water contained in 24h in the ingested food, plus the additional contribution of water during the heat wave was a total of 2583.9 ml / day for the annual average of the 4 times of the year. The annual average urine flow in F-1 was 3.0 ml / min and 0.42 ml / min in Phase 2, see table Nº 1.   Research indicates that in adults, the water deficit and the lack of water in the body, reflect that at this time there is no adequate water supply, so to counteract the adverse effects of increased climate demand, normally take during the summer and spring about 2 liters of liquid a day and an additional contribution of 700 ml / day for the water contained in the food eaten: fruits, vegetables, different meats and fish, cereals, grains and other foods. Additionally, more water must be supplied when the intense heat waves appear during the summer and spring, additionally providing 150 to 200 ml each time the heat waves appear. The diet used was calculated by the balance method based on the recommendations guided by the WHO, which was verified during the period 2013-2016 by Juan, 2017.

Due to the importance of Phase 1 of urine, which represents around 75% of all urine collected on an average day, the behavior of this phase will be analyzed during the different times of the year, which are mainly influenced by the characteristics of the climatic year, the individual and his metabolism, the environment and the contribution of liquid per day, plus the additional contribution by concept of the water contained in the ingested food, plus the additional contribution of water when the climatic demand generally increases by heat wave.

During the winter characterized by low temperatures, the urine collected during Phase 1 was 1412 ml / day / phase, in the spring the urine evacuated was 1392 ml / day / phase. In the summer there was an increase in temperature and an increase in daylight hours, the urine collected during Phase 1 was 1284 ml / day / phase and the total volume decreased compared to 2017 as a result of increased demand climatic, in the autumn the mean temperature decreased again and the urine collected during Phase1was 1330 ml / day / phase, see Table N2.

From the analysis of the influence of climatic factors on urine flow from 3.0 ml / min, which is the most frequent, it is observed that the barometric pressure is the one that has the most influence, following in importance the temperature and relative humidity, the one with the least effect was caused by the wind, see Table No. 3. Climatic factors generally act together on the behavior of urine flow, the most frequent being the combined action of 2 and 3 factors, the least likely is the combination of 4 climatic factors, when a single factor acts the dominant one is the barometric pressure in all its dimensions. In turn, the different climatic factors are influenced by the effect of climate change and global warming, causing them to become increasingly unstable and variable.
