Water is vital to life, and we need to drink water regularly in order to maintain the fluid balance in our body, which should be around 70% at all times. You see, your body loses water throughout the day via various bodily functions such as sweating and urination, and this needs to be replaced.
It is imperative that we drink water throughout the day though, as drinking the daily requirement all in one go could have an adverse effect and result in a condition called water intoxication or hyponatraemia.
Drinking too much water, especially all in one go, can also cause an imbalance in the minerals in your blood due to your blood being too diluted, which means that the minerals become less concentrated, ergo less able to do what they should.
It is far better and healthier to drink a large glass of water first thing in the morning and at regular intervals throughout the day and then end the day off with a glass of water before retiring to counteract the many hours you are asleep and during which your body can dehydrate.
If you are doing an intense workout or prolonged exercise, drink water approximately two hours before; sip water during the exercise and then again after. If the exercise is very long and/or intense, you can also drink a sports beverage that contains electrolytes or minerals, to improve your performance.
Your kidneys filter between 120 and 150 quarts of blood daily, maintaining the correct levels of minerals like calcium, potassium, and sodium, as well as filtering waste. In order to keep your kidneys working properly you need to ensure that there is sufficient water in your body.
If you do not like drinking tap water then it might be time to invest in a water cooler. Mains water coolers are plumbed directly into your main water line (hence the name), and can be fitted with a filter that can filter out all toxins and pollutants, leaving you with chilled, quality drinking water 24/7.
