most helpful answer in 2004 the institute of medicine made a general recommendation of 91oz (a little over 11 cups) for women and 125oz (over 15 cups) for men of total fluid intake each day. there are some things to keep in mind however. it’s estimated that 20-25% of your fluid intake comes from the food that you’re eating. for example lettuce can be around 95% water carrots 87% and broccoli 91%. in fact most of the foods that you eat contain some percentage of water even things like bread. the majority of our fluid intake comes from the liquids we consume. things like tea juice or coffee do count towards that total fluid intake each day. although there is a net gain some liquids that contain caffeine act as a diuretic (meaning that it makes you have to urinate) so there will be some small water loss due to that. prolonged physical activity or heat exposure will also increase water losses and may therefore raise your daily fluid needs. one way to determine your level of hydration is to look at your urine which should be fairly clear. if your urine is a very dark yellow then you may need to be drinking more water. yes it is necessary to drink 8 glass water per day. in todays life everyone is health concious and all want to become fit and away from diseases. we can take other liquid also instead of water for health purpose and for energy level we can take fruits juice fruit tea and other drinks also. yes it needs to be water the other drinks are in addition to.
does the body actually need 64oz of water per day or do other fluids count towards thia total as well? . some days i only post 2 or 3 out of 8 glasses of water on the webmd food and fitness planner chart but i also drink tea coffee and juice during the day. . does it really matter if the liquid isn't water?
