Understand your fluid needs

You should first understand your body's fluid requirements before deciding to drink more water. A frequent daily water intake advice is 64 ounces (1,920 ml), or 8 cups, although this is not supported by evidence.

The National Academy of Medicine (NAM) advises that men drink 125 ounces (3,700 ml) of fluid per day and women drink 90 ounces (2,700 ml). This includes fluid from water, other drinks, and foods. However, NAM acknowledges that making general recommendations for fluid needs isn't optimal because they are dependent on your activity level, location, health status, and other factors. For most people, simply drinking to relieve their thirst will be enough to meet their fluid requirements. However, if you exercise frequently, work outside, or live in a hot climate, you may require to drink more water.
