Quality of life in shift work syndrome.

Air Force radar controllers represent an excellent example of night shift workers, as they are obliged to demonstrate perfect alertness during working hours. We set out: a) to assess the quality of life in these shift workers; b) to identify those with shift work syndrome and c) to evaluate the possible effects of triazolam both on their quality of life and sleep. The results reveal an impairment of the quality of life in shift workers, independently of the presence of a circadian rhythm sleep disorder. Quality of life was more severely impaired in subjects with circadian rhythm sleep disorder. Hypnotic therapy brought about an improvement both in the sleep disorder and in the quality of life of subjects affected by shift work syndrome. Selective alertness tests failed to demonstrate any "sedative carry-over" in the treated patients.
