If you feel adequately hydrated on 64 ounces of water each day, that’s great. If you feel overly hydrated (clear pee and very frequent urination), cut back slightly. If you feel dehydrated (dark pee, headaches, infrequent urination), eight glasses may not be enough for you.
The U.S. National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is: About 15.5 cups (3.7 liters) of fluids a day for men. About 11.5 cups (2.7 liters) of fluids a day for women.
Causes of refusal to eat and drink may include physiologic changes associated with aging, mental disorders including dementia and depression, medical, social, and environmental factors.
