Health and water

Some people believe we feel thirsty whenever our body needs more water. While this is true,recent research studies have indicated that there are several indicators of inadequate water in some or all parts of the body. Ignoring this indicators can lead to several major diseases that medicines may not cure but nit treat. Almost everyone knows that drinking adequate water is good for health. But most people do not understand why this is so and what exactly happen when the body does not get adequate water.
Water prevents several health problems. Up to seventy per cent of the total body weight is due to water. Although it is present in parts of the body, it is more in organs such as lungs and brain and fluids such as blood, lymph, saliva and secretions by the organs of the digestive system.
Water is available liberally in most places. There are two main sources of water - under and surface water. Normally, surface water is 'soft' and underground water is 'hard'. This means that underground water has several minerals and/or compounds mixed in it. Soft water is more effective for therapeutic purposes as compared to hard water.
It is however important to remember that impurities of soft water, if present can adversely affect health, therefore, it is necessary to purify water which will be used for drinking and for therapy.
