Water Theraphy

Did you know that water is a therapy or can heal something? Well, according to what i learn water can help you from any cough and cold you have. Drink a lot of water and you feel good and better. When i have a fever my mom also put a cloth in my forehead that wet with water. She said it will help to cool you from that hot fever. Also it is healthy to drink 6-8 glass of water each day right? I read books about it and that what it said 6-8 glasses of water per day. It will help your system to clean up whatever its in your body. How about you what can you say about water?
