"An apple a day keeps the doctor away." Similarly, if we drink a little more water every day, we may find that we need to go to the doctor less often. A healthy diet is made up of water and different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they offer energy and fiber, without giving us much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for health in all kinds of ways. They believe that many illnesses and health problems appear as a result of dehydration—a lack of water. Most people are dehydrated at least some of time, although they probably don't know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure could be helped if people drink more water. They also believe that drinking more water can help people who are fat. Water contains no calories so it will not make us gain weight. If we drink water, we will probably drink less sugary soft drinks. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water, so we should not stop going to see the doctors completely.
