You may have read that everyone should drink two litres a day as standard but the truth is - everyone's different. Now a team of scientists from Minnesota are proving that. The researchers have devised a simple formula to calculate how much water you should be drinking personally based on your body mass and every individual's results vary.
Here's how it goes...
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.
Divide that number by eight to see your result in cups.
Do note that if you're exercising a lot you will lose water at a more rapid rate meaning you'll need to compensate. The American College of Sports Medicine reports that you should drink an extra 12 ounces of water for every 30 minutes of exercise.
If you struggle to drink large quantities of water, remember that you can also retain hydration from high-water foods such as cucumber, watermelon and celery.
