New research has found a link between drinking water and a reduced risk of heart failure. According to research presented at ESC Congress 2021, staying hydrated throughout life could reduce the risk of developing heart failure. Daily fluid intake recommendations range from 56 to 74 ounces (1.6 to 2.2 liters) for women and 70 to 105 ounces (2 to 3 liters) for men. However, across the world, people rarely consume even the lower ends of these ranges. When the body isn’t properly hydrated, the concentration of serum sodium increases. This directs the body to conserve water, activating a process known to contribute to the development of heart failure. Habitual Fluid Consumption Studies have shown that serum sodium concentration remains within a narrow range over long periods. Previously, many people had thought that hydration and serum sodium would change day to day, depending on water intake. Unfortunately, this isn’t true, and …
