Fatigue remains one of the most persistent human-factor risks in heavy industry, yet the conversation often focuses on managing rosters or tired workers rather than improving how they recover. In this presentation, Toni McQuinn shares insights from a six-week sleep study conducted with Redpath Mining under live operational conditions. The study explored how structured hydration and nutritional sleep support influenced sleep quality, fatigue and recovery across rotating shifts. Toni will discuss the practical lessons from the study and why sleep and recovery should be viewed not simply as wellbeing issues, but as important contributors to cognitive readiness, workplace safety and human performance.
