IMPORTANT FACTS ABOUT WATER

Most people need between 8 and

12 cups of fluid a day (about 2-3 litres).

Needs vary, of course, depending

on your age, your gender and how

active you are. But in general for every

50 pounds of body weight, you need

about a quart of water every day (or

about a litre for every 25 kg of body

weight). For most people that falls

within the often-cited suggestion that

we take in at least 8 glasses a day.

DO YOU KNOW

WHY PROPER

HYDRATION IS

SO IMPORTANT?

Around 60-70% of the

human body is composed of

water, so it’s fair to say that

water is vital for survival. It

functions to keep our body

temperature regulated,

takes part in digestion and

excretion, contributes to

cognitive functions* and

physical performance,

just to name a few!

Drinking fluids with meals is fine: water won’t dilute

digestive juices or impair your digestion in any way. It

doesn’t really matter when you take in water, as long as

you get what you need over the course of the day.

Fruits and veggies

can provide 20%

or more of your

water needs.

Watery foods can

go a long way

towards meeting

your fluid needs. If

your meals include

plenty of fruits and

vegetables, and

you drink fluids

with meals, you’re

probably meeting

your water needs.

There are nearly

3 cups of water in a

meal that includes

a salad, some

broccoli, brown rice

and watermelon

for dessert. On the

other hand, too

many people eat

a ‘dry’ diet that’s

heavy on processed

foods—a meal of

a cheeseburger

and a bag of chips

contain less than

half a cup of fluid.

The temperature of your water doesn’t really matter. In

terms of hydration, it doesn’t matter if liquids are warm,

cool or cold. They’ll all hydrate you equally, although

temperature will affect the rate at which you consume

them. Some people think that ice cold water will help

you lose weight—the idea being that you’ll burn calories

bringing the fluid to body temperature. In theory you

could, but the amount of calories you’d use up is so

tiny that it’s nearly insignificant. And you’d also have the

‘brain freeze’ to deal with.

DID YOU KNOW?

Studies have shown as little as 1% dehydration can cause

major changes in body temperature, while 2% dehydration

will drop your performance levels significantly!**
