RNAO’s best practice guideline on fatigue  states that contributing risk factors for fatigue include: on-call hours, mandatory over-time, working while sick, inadequate rest between shifts and rotating shifts within the work week. Personal factors include: working more than one job, age, home and family responsibilities, physical and mental health, and working voluntary overtime.
The top five factors contributing to fatigue in nurses, according to RNAO and CNA’s 2010 study on fatigue, were: increased workload, working short staffed, increasing expectations from patients and families, high levels of patient acuity and unexpected emergency with staffing or patients.
Tips on how to beat fatigue
Eating well, resting adequately between shifts, participating in physical activity outside of work, and communicating shift preference when you know the personal impacts linked to shift patterns.
Sleep well by: ensuring your bedroom is cool, blocking out distracting noise, and installing dark shades.
