That is, less pain. According to a research done in Howard Florey Institute in Australia, thirsty people are more sensitive to pain. Study participants had their thumbs squeezed to urge slight pain. Then a saline solution was injected to induce thirst. The subjects all had a PET scan to see if there were any changes in brain activity and blood flow.

The thumb pressure subjected to the participant was constant. However, they continue to become thirstier. As the level of their electrolyte went down, the more pain they felt.Why? The study indicated that a part of the brain is activated when pain and thirst are experienced simultaneously. A "priority" switch of some sort is triggered and pain is more emphasized because it is a greater threat than thirst.

Water: no calories, natural pain reliever!
