Construction workers from two public works departments in Portland, OR, completed three surveys over a 12-month period. The data collected, which was part of an Oregon Healthy Workforce Center study, was used to determine the respondents’ self-reported sleep quality and quantity, and was then compared with subsequent reports on safety behavior and workplace injuries.

Respondents who reported more insomnia symptoms, on average, experienced more “cognitive failures” – such as lapses in attention, memory or action – at work. More failures were related to an increase in minor injuries and a reduction in required and voluntary safety behaviors.

Among the cognitive failures:

• Not remembering correct work procedures or if equipment was turned off.
• Unintentionally pressing a control switch on machines.
• Stopping or starting the wrong machine unintentionally.
• Daydreaming instead of listening to a co-worker.
