Quite an interesting article I have just read today.

I am always being told I don’t drink enough water.They tell me I should be drinking 2 litres a day , but really weight , gender and age also come into the equation. I personally struggle to drink anywhere near two litres or 3.5 pints.That seems an awful lot to me.But the experts say ……

How much water you should REALLY drink in a day revealed (and there‚Äôs a simple formula to use to calculate the amount you need as it’s different for everyone)

  • It also reports women should drink about nine cups
  • But as every body is different a formula can work out the exact amount you need

From feeling less tired to clearing up spots, drinking enough water can cure all sorts of ills.

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.

Symptoms of dehydration can include dry skin, a headache, dizziness and even fainting

How much water should you be drinking?

The formula for how much water you should be drinking:

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.

If you’ve been drinking enough water throughout the day, your urine should be a very pale colour rather than a deep yellow

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.

However, eating salty foods can do the opposite as your body will retain fluids to help dilute the sodium you’ve just consumed – which is why we often bloat after eating sodium-rich foods, and get thirsty.

My calculation comes to 23 cups and this seems a bit excessive even for a fat B like me lol This is almost 3 litres .I worked it out for the Mrs and it was 19 cups .I noticed the calculation didn’t take into account your gender .It would seem to me the equation is wrong. 1 litre = 33.8 us fluid ozs and a cup = 8 fluid ozs
