I heart water

Too much salt intake is bad for the heart, resulting in enlargement and thickening of the organ and a higher risk of failure. Researchers looked at the balance of salt and water in blood and found that people who stayed well hydrated had lower risk of cardiovascular disease. What does it mean to be “well hydrated?” Researchers translated that to 6 to 8 cups (1.5 to 2.1 liters) a day for women and 8 to 12 cups (2 to 3 liters) for men.
