How much water should you be drinking?


We’re all told to drink lots of water and cut down on coffee, cola and alcohol. But why should we drink water and how much do we really need?

Let’s start with the physiology. Humans are composed of about 75 per cent water and it plays many important roles in our bodily functions including digesting food, lubricating joints and maintaining body temperature.

Water is the most important nutrient that humans need. We can live without food for around 3 weeks but we can’t survive longer than 3 days without water.

Water creates a stable environment inside and around our cells, allowing us to get nutrition into our cells and eliminate waste from our cells.

Even the brain is made up of 80 per cent water. It is an essential part of our survival.

Our body is only designed to drink water and nothing else but water. When we drink anything else it is simply drying out the body.

Drinking liquids that are not water are displacing agents or diuretics.

Each time you drink any other source you are displacing the intake of a health giving fluid and consuming empty calories, which will eventually lead to weight gain.

This means if you drink a cup of coffee or cola in a day then you will need to drink the equivalent quantity in water just to balance out your hydration levels.

Most people are in a chronic state of dehydration. A dry mouth and bright yellow urine are clear indications that you are already dehydrated.

As water is so important to the survival of the body it will scavenge water from any system just to stay alive, mainly the digestive and musculoskeletal systems, leading to a host of seemingly unrelated disorders.

To ensure you stay hydrated, calculate your bodyweight in kilograms and multiply it by 0.033. This is how much you need to drink in litres. For example, I weigh 80kg so I need to drink 2.7 litres a day

Try and drink filtered or bottled spring water and avoid cloudy plastic containers, as they are prone to leaching chemicals into the water.

Drink up and enjoy the benefits of a fully hydrated body. The worst that will happen is a few more toilet breaks.
