- The study investigated how early morning shifts affect train drivers' sleep and alertness during normal work conditions.
- A total of 17 experienced drivers were observed on three different shifts, with results indicating that early shifts significantly reduced sleep duration and led to high levels of severe sleepiness (82% experienced this).
- The research highlighted an increased risk of severe sleepiness in early shifts, especially during longer drives, suggesting that early morning workers face greater risks, emphasizing the need for increased monitoring and risk assessment in such circumstances.
