Dr. Fereydoon Batmanghelidj is the author of the book "Your Body's Many Cries for Water" in which he states that the main cause for the majority of todays health problems is mild to severe dehydration which is caused by the fact that people are not drinking enough water. He came to this realization while he was in prison during the 1979 revolution in Iran. There he treated a man who was having pain in his stomach caused by ulcers, the doctor gave him two glasses of water and short time after that the pain stopped.
After this dr. Batmanghelidj came to a conclusion that water could be used to prevent or even solve a large amount of todays ills, and majority of nutritionists agree with that. Todays way of like makes us neglect our water intake, and even if we do drink, we drink coffee, alcohol and various kinds of juices. What doctor suggest in his book is that we should drink 2 deciliters of water 6-8 times a day, spread out evenly through out the day. The problem lies also in the fact that today we have a decreased sense of thirst, and the rule is that when we feel thirsty we are already dehydrated. Once that happens, even if it is a minimum dehydration our metabolism is slowed down, and in the long run this could cause problems with blood pressure, circulation and with our digestion.
By drinking water you prevent the onset of the previously said conditions due to low levels of water in your body, but it has been noticed that drinking water can help eliminate conditions such as stomach ulcers, rheumatoid arthritis and high blood pressure, even though claims of healing are still highly speculative, and other variables specific to each case should be taken into consideration. Another good thing that you get by drinking proper amounts of water you avoid the use of drugs which could be expensive or even dangerous for you.
Some neurologists believe that frequent headaches could be connected to low intake of watter, and not only that, but also on loss of concentration and a decrease in the intelligence. All in all, almost everybody agrees that it's very important to obtain a habit of drinking water even when you are not thirsty in order to maintain bodily function at a satisfactory levels, and remember, when you are thirsty you already have a shortage of water in your body, so react before that.
