How Much Water Do You Need?
We are constantly losing water from our bodies, mostly through urine and sweat. If this water is not replaced the body is forced to recycle the water in our system by re-filtering it through the kidneys. This ultimately places extra, unnecessary strain on our kidney and liver. Why not avoid this whenever possible?
So, how much water do you need daily?
The Traditional Answer
Health authorities commonly recommend eight 236 ml (8 ounces) glasses of water, which is around 2 litres daily. This is called the 8×8 rule (8 servings of 8 ounces of water daily) and it can be very helpful but only to a certain degree as it does not consider all factors.
Other health experts say that we should drink water consistently throughout the day as we are always facing the danger of dehydration.
Other, Likely More Accurate Answers
This problem with these answers is that they fail to factor in the internal and external circumstances of different individuals. One person may drink eight glasses of water daily, but still be at the risk of dehydration because of other factors.
One school of thought says the quantity of water to take daily depends on your body weight. Take your weight in kilogrammes and divide by 20; this gives you the amount in litres you should be drinking daily (eg, 3.5 litres if you weigh 70 kilogrammes)—if you led an average lifestyle.
Another school of thought: drink enough water to ensure your urine is a light-coloured yellow, but without having to urinate more than seven to eight times a day.
Water Intoxication is drinking an extreme amount of water (eg, six litres) in a short period. It can be dangerous, even fatal. Stick to drinking water regularly throughout the day to get the maximum benefits.
Ayurveda, the ancient Indian system of medicine, recommends drinking one litre of warm water immediately on getting up from bed, ie on an empty stomach. This practice hydrates your body after a night of sleep, and purifies your system. The remaining amount of water you should be drinking can be taken throughout during the day.
