We are presently looking at the health and personality profiles of subjects who claim to be noise sensitive during sleep, but who are probably not, vs subjects who we think are noise sensitive but do not realise it. Funded by the Civil Aviation Authority. Fatigue and Alertness in Seafarers. The shipboard environment has changed recently, with new technology, together with reduced and more international crews as recruitment extends overseas. Findings showed that differences in sleep quality and duration between work and home were more evident for split-shift workers, and that they also experienced greater sleep disturbance and shorter sleep periods than those working a single shift each day.
Further research is needed on a larger sample of split-shift crew.
The photograph shows a typical ships bridge, where the seafarer spends his time on watch, monitoring different instruments, as well as the environment surrounding the ship.
