2.2 Water – The Elixir of Life


The first question that arises with the consumption of water is how much to consume? The hydration needs of individuals are different. It depends upon factors like health condition, activity level and climatic conditions. The level of water intake depends on body weight, age, gender and the fat content in the body. There are adverse effects of lack of water consumption like hindrance in the excretion of uric acid, uria and calcium. This affects the electrolyte balance adversely which may lead to coma and death of a person or kidney malfunction. Water is the elixir of life and it is required for life processes like breathing, digestion and metabolism. It also helps in cooling the body through perspiration and lubricates the joints. The National Institute of Nutrition issued guidelines stating that the minimum daily water consumption by an individual should be 2 litres or 8 glasses of water. To maintain an optimum hydration one must consume low calorie nutritious beverages like lemon water, green tea, coconut water and buttermilk. Many places in India are facing water scarcity so we must implement ways to conserve water. Few of these include rain water harvesting, judicious use of water and even treatment of sea water to meet the scarcity.
