According to recent studies, people who maintain a healthy level of hydration have a decreased risk of developing chronic diseases and live longer than those who do not.
The National Institutes of Health study, which was published in eBioMedicine, examined the health records of 11,255 individuals. Five medical visits over a 30-year span were used to collect the data; the first two took place when the participants were in their 50s and the final occurred when they were between the ages of 70 and 90.
