How Much Water Should You Drink?
Follow Some General Guidelines
Many people think you should drink eight 8-ounce glasses of water per day. There really is no evidence to back that up, but it's an easy approximate amount to remember. The amount of water you should drink every day depends on a variety of factors including your weight, activity level, the weather, and how much you sweat. In reality, people meet their daily fluid requirements by drinking water and other beverages. We also get water from food that we eat. People get about 80% of their daily fluids from drinking water and other beverages. About 20% of total water comes from food. In general, an adult woman needs approximately 11 cups of total water per day from food and beverages. An adult man needs approximately 15 1/2 cups of total water per day. Caffeinated beverages have a slight diuretic effect. Of course if you are thirsty, you need to drink more fluids. Adequate hydration aids in weight loss and has numerous other healthy benefits.
