There’s a formula for measuring your body’s water requirements

There are few among us who don't – on some level – know that we should be drinking more water.

And while we may chug a litre before, during and after a work-out or drink it by the bucket-load when we're hungover, not all of us are as judicious when it comes to staying hydrated on a day-to-day basis.

If you respond well to limits and like to know when you're hitting a target, then it might be worth considering your water intake in relation to your body weight.

Here's what you need to do:

Establish your weight in lbs and divide that figure in half. This figure is the number of ounces of water you need to consume per day.

And since we work in litres here, you should know that there are 33 ounces to every litre.

It's also important to note that this calculation is based on the body at rest which means when you're sitting at your desk or pottering around your house, but it's a good starting point, right?
