It’s no secret that water is important to your health, but many Americans don’t get the recommended 30 to 50 ounces per day. This can cause health issues like dehydration, muscle cramping, and fatigue.

Experts used to prescribe eight glasses of water a day, but now suggest that people who aren’t very active divide their body weight in half and drink that amount of water in ounces. A 160-pound person, for example, would aim for 80 ounces of water daily, which can come from water as well as watery foods.
