Sleep -- it's something we do every day, but why do we sleep and why are psychologists so interested in sleep? What happens if we don't sleep? Sleep has been the subject of extensive research over many years, and while our knowledge and understanding about sleep, and the role it plays in keeping us healthily alive, has advanced considerably over the past few decades, there is still much we don't know.
This film examines sleep and why human beings do it, the nature of sleep including the four stages of sleep, and looks at the causes and impact of not sleeping. It is presented by psychologist Dr Steve Taylor and includes expert comments from Prof. Kevin Morgan and Prof. Jim Horne from the University of Loughborough, and Prof. Gareth Gaskell from the University of York. It is an excellent resource for Psychology students at senior secondary level, as well as those undertaking tertiary and further education studies.
