Drink eight glasses of water a day – you probably heard this advice ever since you were a kid, but do you follow it faithfully?

Now, there’s reason to make a conscious effort to do so. Daily Mail writer Sarah Smith challenged herself to drinking three litres of water per day for four weeks, to see if her health and skin will improve if she followed this age-old water rule.

Besides having to visit the toilet more often, Smith discovered that drinking more water helped improve her joint flexibility, her complexion, her breath, and her headaches. Collectively, it helps improve her concentration ability.

Now, what’s also very interesting is that she managed to lose two pounds (that’s almost 1kg) and half an inch off her waist – all these just by drinking more water, and not making any changes to her diet or fitness regime.

Smith says, “I’m eating less because drinking water with meals makes me feel fuller quicker. I used to snack, but I was reaching for food when I was actually thirsty. Studies show 37 percent of people mistake thirst for hunger.”

And it goes beyond just weight management. Smith’s eyes were reportedly suffering from dark circles in the past and now her eyes are clearer, sharper and righter.

Smith wrote that she felt fitter, leaner and healthier, and her friends and husband even tell her that she looks ten years younger now.

Now, pass us those water bottles!
