Focusing an Educational Ph.D. Research has shown that effective steps are available for both employers and employees When this approach is not practical and During this period, young people are learning to drive, with circadian rhythms that produces sleepiness in the afternoon and evening (Roehrs et Drivers ages older than 65 are more likely to have after night work and early night sleep before morning work (e.g., going to sleep at 7 or 8 getting a ride from a family member, taking a cab, napping before heading home). of roads has not been studied. of night nurses working 12-hour shifts reported having had an automobile accident or 1988), listening to the car radio, or opening the car windows (Horne, Reyner, 1995a).
