Drinking Water Myths

MYTH: You Can't Drink Too Much Water

It is possible to drink too much, over consumption of water can lead to a potentially fatal condition called Hypernatremia also known as Water Intoxication. Source:

MYTH: Drink Eight Glasses Per Day

Common advice is to “drink eight 8-ounce glasses of water per day” which is about 1.9 litres. We are calling this a Myth as (although it approximates other guidance) no one seems to know quite where the advice originated from. Source:

MYTH: Drinking Water Helps Lose Weight

Water will not cause you to lose weight however the NHS states that it “…might help you snack less…” and that “…Sometimes thirst can be mistaken for hunger; if you're thirsty you may snack more.” Source:

MYTH: You Can Only Hydrate With Water

Not true; water is great as it contains no calories or sugars, however milk and fruit juice are also good, provided you understand the amount of sugar you're consuming. In addition a large proportion of your fluid intake can come from the food you eat.

General Fluid Intake Guidance

What you need to drink depends on many factors including, what you've eaten, your health, age, the climate and any physical activity.

The factors involved are too numerous to leave us with definitive guidance on the amount an individual should drink, but the general guidance that we found online is as follows:

The Institute of Medicine (US)

According to the Mayo Clinic the Institute of Medicine determined that “…an adequate intake (AI) for men is roughly 3 liters (about 13 cups) of total beverages a day. The AI for women is 2.2 liters (about 9 cups) of total beverages a day…” Source:

Department of Health (UK)

The Department of Health suggest that you drink 6-8 glasses (about 1.2 litres) of fluid a day if you live in the UK that's 6 200ml OR 8 150ml glasses, cups or mugs. Source:

Other Factors:

Other factors that affect how much water you need may include:


A large proportion of your fluid intake can come from food, for example Melons have a high water content which may count towards the amount that a person needs to drink in a day.

Exercise and Activity

If engaged in exercise or other activity you may need to consume extra fluid to compensate for the fluid loss.


Hot or humid conditions and altitude, all may have an effect on the amount of water you require.

Medication, Medical Conditions and Health Issues

Some people on medication or with medical conditions should either increase or decrease the amount of water that they drink. If you are taking medication, have any sort of medical condition, or health issue you should seek hydration advice from your own GP or appropriate health care professional.

Pregnancy or Breast Feeding

If you are expecting or breast-feeding you will need additional fluids to stay hydrated and should seek hydration advice from your own GP or appropriate health care professional.

Age and Weight

Children, the elderly or the obese may need to maintain different levels of hydration and should seek hydration advice from your own GP or appropriate health care professional.

Additional - What Should We Drink?

All drinks help us stay hydrated but some are considered better than others:

  • Water is best, as it contains no calories or sugars
  • Milk and Fruit Juice are also good but watch out for the sugar
  • Alcohol is not advisable
  • Despite the Myths Tea and Coffee are generally considered fine in moderation, although not for toddlers, children or pregnant women

Tip: If you don't like plain water consider adding fruit juice or add a slice of lemon or lime to improve the taste.


Additional - How Much Water Do We Lose Per Day? **

  • Our bodies loose a total amount of 2.5 liters.
  • We typically get 1 Liter back from food.
  • Our bodies make 0.3 Liters through Chemical reactions.
  • We therefore need to drink 1.2 litres per day.

** Water loss is increased when the temperature rises or when we participate in more activity.
