Drinking enough water every day is good for overall health. It has zero calories, helps manage body weight, and reduces caloric intake when substituted for drinks with calories, like regular soda. Drinking water can prevent dehydration, a condition that can cause unclear thinking, result in mood change, cause your body to overheat, constipation, and kidney stones.
The National Academy of Medicine suggests an adequate intake of daily fluids of about 13 cups and 9 cups for healthy men and women, respectively, with 1 cup equaling 8 oz (240 ml). Higher amounts may be needed for those who are physically active or exposed to hot climates.
Lower amounts may be required for those with smaller body sizes. It’s important to note that this amount is not a daily target but a general guide. In the average person, drinking less will not necessarily compromise one’s health as each person’s exact fluid needs vary.
