Different authorities gives different opinion about how much water we can drink per day. The Health Authorities commonly advised to drink 8 glasses (nearly 2L) of water. However, the amount of water taken by a person may vary according to his working/living conditions. Athletes, people working/living in warm climatic conditions or people engaged in work which need a lot of physical energy may take more amount as they need more. Water itself acts as nourishment for the body, if taken appropriately. Otherwise, as “Excess of everything is bad”, water can also act as poison.
1. Over drinking of water is known as over-hydration. Due to over-hydration, our kidneys are forced to function more, which may leads to the damage. Drinking more water than what the kidney can get rid of in the form of urine can cause too much water to collect in the body which leads to swelling. It also causes loss of essential minerals in the form of sweat.
2. Over drinking of water can cause an increase in the volume of blood (by diluting) which may create more pressure on our heart.
3. Drinking more water than our actual requirement may affect the function of our vital organs and subsequently may cause headache, vomiting and nausea.
4. Over drinking of water is potentially deadly. Drinking large amount of water, particularly at the end of the day can disrupt sleep too. So better avoid drinking water before 2/3 hours to bed time. The amount of water, one should drink, will vary from person to person. The bigger and more active you are, the more fluids you will need. The best way to follow is “DRINK WHILE THIRSTY”. We can also drink more or less by keeping an eye on the color of the urine. Ideally urine should be of light, straw color. Always drink water slowly, sip by sip. On average, food we eat provides 20% of total water intake. For example many fruits and vegetables. In addition, beverages, such as milk, juice, beer, wine and even coffee, tea or soda can contribute a portion of our daily total fluid intake. Water is still THE BEST BET because it is calorie free, inexpensive and readily available.
