Does staying hydrated help prevent colds and flu?

Dr. Andrea Pennington, MD
Integrative Medicine
Staying hydrated helps to keep your whole body operating at its best. For your body to fight infection, it needs adequate water. So to avoid dehydration, be sure to drink enough water to make your urine clear. For most, drinking 6 to 8 eight ounce glasses of water each day will do the trick. Water is the best choice; you want to be sure not to drink too much soda, coffee or sugary juice drinks which can actually dehydrate you. While orange juice can help because of the vitamin C, limit yourself to 8 ounces each day to be sure to get enough water in. Also, decaf green tea can be soothing and has immune-boosting antioxidants.
