How Much Fluid Should We Drink Each Day?
Paying attention to hydration, especially in times of physical exertion and stress is important. So, exactly how much liquid should we consume each day? There is no one size fits all formula for everyone. The Center for Disease Control and Prevention (CDC), which defines Daily Fluid Intake as the amount of water consumed from foods, plain drinking water, and other beverages and advises that the specific amount of daily fluid intake required will vary based on individual age, sex, pregnancy and health status (2017).
A 2015 article points out that most healthy individuals successfully meet daily fluid intake requirements by responding to thirst cues in combination with the water content in the foods that they eat, cautioning that heat, physical activity, and medical condition may significantly impact fluid intake requirements,
“…Even a healthy person’s water needs will vary, especially if you’re losing water through sweat because you’re exercising, or because you’re outside on a hot day. If you’re wondering how much water should you drink on those occasions, speak with your doctor, but a general rule of thumb for healthy people is to drink two to three cups of water per hour, or more if you’re sweating heavily.”
It is important for individuals with specific medical needs or questions about fluid consumption to consult their health-care provider.
Paying attention to hydration is an easy way to care for your health.
