“Fatigue” and “sleepiness” often are used synonymously, but they are not the same. Sleepiness is the physiological desire to sleep. Fatigue describes a physical, mental or social impairment that includes tiredness, sleepiness, reduced energy and increased effort needed to perform tasks at a desired level. Nearly 4 out of 10 employees in the U.S. suffer from sleep loss. People most at risk for fatigue and fatigue-related incidents include:

• Shift workers, especially those working night shift, rotating shifts, long hours or with early morning start times
• Workers who perform a task for extended periods or repeatedly perform a tedious task
• Individuals who get less than seven hours of sleep a night
• Individuals with untreated sleep disorders such as obstructive sleep apnea
• Parents and caregivers of young children
• People taking certain medications that interfere with sleep
