饮用足够的水能帮你缓解疲劳，还能祛斑，可谓“包治百病”。
But the majority of people simply don't drink enough of it.
Medical research centre the Mayo Clinic in Minnesota reveals that men should be drinking 13 cups of it a day on average, while women could consume nine.
But every person's body is different - and the amount you really need to drink can be worked out using a simple scientific formula.
Step 1: Take your weight (in lbs) and divide it by 2.2.
Step 2: Multiply that number by your age.
Step 3: Divide that sum by 28.3.
Step 4: Your total is how many ounces of water you should drink each day.
Step 5: Divide that number by eight to see your result in cups.
However if you exercise regularly, you'll of course need to drink even more water to replace the liquid you'll lose through sweat.
The American College of Sports Medicine reports that you should drink an extra 12 ounces of water for every 30 minutes of exercise.
Your diet can play a large role in helping to keep you hydrated.
Eating foods with a high water content, such as watermelon, cucumber and celery, can help flush out toxins in your body.
