all three groups experienced a higher pain threshold and a higher pain tolerance than previous to the film. The results did not show a significant difference between the three groups. There are also potential relationships between humour and having a healthy immune system. SIgA is a type of antibody that protects the body from infections. In a method similar to the previous experiment, the participants were shown a short humorous video clip and then tested for the effects. The participants showed a significant increase in SIgA levels. There have been claims that laughter can be a supplement for cardiovascular exercise and might increase muscle tone. However an early study by Paskind J. showed that laughter can lead to a decrease in skeletal muscle tone because the short intense muscle contractions caused by laughter are followed by longer periods of muscle relaxation. The cardiovascular benefits of laughter also seem to be just a figment of imagination as a study that was designed to test oxygen saturation levels produced by laughter, showed that even though laughter creates sporadic episodes of deep breathing, oxygen saturation levels are not affected. As humour is often used to ease tension, it might make sense that the same would be true for anxiety. A study by Yovetich N, Dale A, Hudak M. was designed to test the effects humour might have on relieving anxiety. The study subject were told that they would be given to an electric shock after a certain period of time. One group was exposed to humorous content, while the other was not. The anxiety levels were measured through self-report measures as well as the heart rate. Subjects which rated high on sense of humour reported less anxiety in both groups, while subjects which rated lower on sense of humour reported less anxiety in the group which was exposed to the humorous material. However, there was not a significant difference in the heart rate between the subjects. In the workplace Humour is a ubiquitous, highly ingrained, and largely meaningful aspect of human experience and is therefore decidedly relevant in organisational contexts, such as the workplace. The significant role that laughter and fun play in organisational life has been seen as a sociological phenomenon and has increasingly been recognised as also creating a sense of involvement and possible comradery among workers. Sharing humour at work not only offers a relief from boredom, but can also
