Scientists at the University of Aberdeen recently collaborated with others to figure out how much water people really need . People only need about 1.5 to 1.8 litres of water a day, less than the recommended two litres .
It is a well-known fact that to remain healthy and hydrated, a person should drink at least two litres of water a day, as well as being advised by doctors and specialists.However, new studies have shown that the recommended eight glasses of water a day may be too much.Though it isn't harmful, it is not needed in all circumstances.Scientists at the University of Aberdeen recently collaborated with others to figure out how much water people really need.People were recruited by a glass of water in which some of the hydrogen molecules were replaced by a stable isotope of the element called deuterium, which is found naturally in the human body and is completely harmless, according to the study.The rate at which the extra deuterium is eliminated determines how quickly the body's water is evaporating.People with a higher water turnover, according to the survey, must drink more water in hot and humid conditions and at high altitudes, as well as athletes and breastfeeding women, as the water turnover is higher among them.Men aged 20-35 consumed an average of 4.2 litres of water per day, while women aged 20-40 consumed 3.3 litres, according to Professor John Speakman of the University of Aberdeen, who told Radios Good Morning Scotland that the initial estimate of two litres per day came from a slight error. They estimated the amount of food by asking people how much they eat.Mr Speakman said that because people under-report how much they consume, there is a miscalculation and that overestimating the amount of water needed is unnecessary.He also explained that water turnover is not proportional to the amount of drinking water required.Even if a male in his 20s has a 4.2 litres of water per day, he does not need to drink 4.2 litres of water a day, he said. About 3.6 litres of water per day is sufficient.Since most foods contain water, a substantial amount of water is obtained by eating.Featured Video Of The DayBJPs Gujarat Poll Candidate Hardik Patel On leaving the party, the bridge tragedy, and the 2002 Riots.
