Why Do We Feel the Thirst?
People think that they feel the thirst when their throat gets dried or when the saliva in the mouth is not produced to the required amount. In the normal conditions, the amount of water and minerals in the blood will be equal. When the amount of water in the blood gets reduced, brain will send the instructions to the throat that water is required. For this reason, people feel the thirst. At some times, we feel the thirst even if we are having required amount of water in the blood. Reason for this is thirst feeling is that people eat more salt contained foods and this will create imbalance in the amount of water and minerals in the body. As a result, brain sends the instructions to the throat and people feel the thirst.
