Today it is precisely these occupational groups who are most busy. There has been a fundamental change in society that we can't fully comprehend, and it has taken place very rapidly. Another striking feature is that there aren't any groups who are critical of this development. Physiological measurements were not undertaken, but emphasis was placed on finding sociological explanations for tiredness and dealing with tiredness. There has not been much research on tiredness as a subject.
All people experience tiredness, but it manifests itself in different ways.
This project looked at the many forms of tiredness and analysed the different social types of tiredness. A number of occupational groups were investigated, including teachers, engineers and auxiliary nurses. Sex, social class, generation and family situation were other important categories. There are great variations among the groups. If one is to do anything about the problem of tiredness, one must consequently do something locally, suited to the particular situation.
