Sleep of shiftworkers within the arctic circle

Aviat Space Environ Med. 1984 Nov;55(11):1026-30.


The sleep of shiftworkers in the Arctic has been investigated using electroencephalography. The subjects were studied four times a year over a 2-year period. There was a trend toward less restful sleep during the autumn and winter months, but otherwise sleep at various times of the day was similar to that of individuals elsewhere. This would suggest that sleep disturbance in polar shiftworkers can be managed in a similar way to that of shiftworkers in temperate regions.
