Why do you think we feel more thirsty when we exercise or
when we are tense? Many people think that parching of mouth or throat is only
caused by thirst. But, this is not true. Such parching can occur due to many
other cases also. Tension or production of less saliva by the salivary glands
as also produces thirst and so can nervousness. Have you ever wondered why we
feel thirsty? Present in our blood. The body tissues also contain these two
substances. Under the normal condition, the proportion of these two materials
in blood remains constant. If due to some reason, the amount of water in blood
gets reduced, the proportion of these two materials in blood remains constant. If
due to some reason, the proportion of the two materials also changes. In such a
situation, the thirst center located in the brain sends signals to the throat.
As a result of this, the throat starts contracting. This contraction makes it
dry ad we start feeling thirsty and want to drink water.

We feel thirsty when the amount of water in blood gets reduced
However, sometimes, the salivary glands secrete enough saliva
and our stomach and blood too have enough water and yet we feel thirsty. For
example, when man drinks liquor he takes enough quantity of slated preparations
along with the drink. Though the amount of water goes on increasing with the
intake of liquor, consumption of salted foods also increases the quantity of
salt in blood. As a result of this, the amount of salt in blood exceeds the
normal level. This disturbs the normal proportion of salt and water in the
blood. In such a situation, we feel thirsty. Excessive thirst may be a symptom
of diabetes or kidneys ailments. In such cases, immediate medical check up
should be undertaken.
