The physical toll of stress can be debilitating, but can sometimes be hidden. What are the warning signs, and what's the link with the stress hormone cortisol? By pinpointing the moment of optimum stress, teachers can start to control the cause of their stress and so reduce it. Professor Cary Cooper from Lancaster University is joined by occupational psychologist Emma Donaldson-Feilder in the last of this series of Stress Relief for Schools. Making use of scientific data gathered at the Kings Langley Secondary School, our psychologists explore the physiology of stress. They also follow the career of a teacher who appears remarkably relaxed after 20 years experience in the classroom. But concern mounts as it transpires that the surface calm is masking some worrying physiological readings. Is it the presence of cameras that is causing this stress or something else?
