We all know that water is the source life Earth. No plant, insect, animal or human can survive it. A new study highlights how important it is to our health and to living longer. The study is the National Institutes of Health in the USA. Researchers found that people who drank a lot water every day were healthier and lived longer than those who didn't. The research team said people who stay well hydrated developed fewer serious health problems and age-related illnesses, heart and lung disease. They added that adults who did not drink enough water were more likely to die a younger age. These adults were also more likely to show signs ageing.

The researchers looked health data 11,255 adults a 30-year period. They analyzed the information patients who had visited a hospital least five times. The first three times were when the patients were their 50s, and the last two times were when they were aged between 70 and 90. Dr Natalia Dmitrieva, lead researcher the study, said: "The results suggest that proper hydration may slow down ageing and prolong a disease-free life." She encouraged people to drink more fluids, water and juice, and fruit and vegetables a high water content. She added that half people worldwide do not drink enough. The average adult needs to drink least 1.5 litres water every day.
