Studying yawning has the potentially benefit of identifying underlying neurological disorders. Strong evidence of a link between yawning and fatigue, and with multiple sclerosis, is known. Mechanisms involved in excessive yawning are not understood and my work has shown a definitive link between yawning and cortisol levels in normal people. However, since people with multiple sclerosis often yawn excessively, it is important to establish whether or not their cortisol levels rise as with normal people since prolonged rises in cortisol levels indicate stress and may also indicate adverse neurological symptomatology. My work has generated a new hypothesis to explain the occurrence of excessive yawning and is complementary to Dr Gallup’s theories on thermoregulation in multiple sclerosis, which is pioneering. I am meeting Dr Gallup (Princeton University) in New York to discuss further studies in order to stay ahead of research progress. This is an excellent opportunity for kudos for Bournemouth University in being the first to carry out such research.
