When it is said that a bit of stress is good then experts are not faking it. It has been recently revealed through a US study that short-term stress is good for immune system and enhances the performance.

The study, which has found its place in Psychoneuroendocrinology, was being carried out by a group of researchers from the Stanford University School of Medicine and two other institutions. The newly published study has made it clear that short-term success can become a source of success.

The study findings were based on an experiment, which was being carried out on rats. "The study, conducted in rats, adds weight to evidence that immune responsiveness is heightened, rather than suppressed as many believe, by the so-called 'fight-or-flight' response", said study researchers.

Lead author Firdaus Dhabhar from the Stanford Institute was of the view that little stress alerts brain and other body parts to remain active for challenge. This way, one tends to give an exceptionally well performance.

Dhabhar said that he has been carrying out study on stress hormones and its effect on immune system for last 10 years, and has noticed that improved performance credit should go to short term stress that people take before carrying out any task.
