Water, as many of us know is essential for survival, but exactly how much water should we be drinking? Doctors recommend 8-9 cup of water a day that is about half a gallon of water. However, if you’re performing strenuous physical activities 1 gallon of water is recommended ( that is eight 16oz water bottles , in case you didn’t want to lug around a gallon of water like I do ). But why so much?
