Water Water Water

There is a lot of water present in our body. Our body has
70 % water.

Why is there so much water in our body? Here are the
reasons :

w Water helps the food to move through the digestive
and excretory systems.

w It helps the body to digest nutrients.
w It is a major part of blood.

w It maintains body temperature by distributing the
heat through the body and losing excess of it in the

form of sweat.
w It surrounds and protects the delicate body parts

like the eyes, brain and the spinal cord.
w It keeps our eyes bright, skin soft and hair shining.

When you feel thirsty, it is your body's way of telling you to drink water and
fulfil its (the body's) need of water. The body loses water in the form of sweat,

urine and as vapours while exhaling. The amount of water needed by the body
depends on one's age, outside temperature, humidity etc. Usually, we need to
drink 8 to 10 glasses of water everyday.

Roughage
Roughage is the fibre present in the
food. It helps the body to get rid of

wastes. Thus, it prevents us from being
constipated. Green leafy vegetables,
fibrous fruits like orange, papaya etc.,

are rich sources of roughage. We must
include roughage in our diet.
