How Does Fatigue Effect you?
Fatigue stressors may increase risk of a fatigue-related incident. When people become fatigued they have trouble paying attention, they think more slowly, make more errors, become forgetful, and may even fall asleep on the job
The Psychomotor Vigilance Test (PVT) measures changes in psychomotor speed, lapses of attention, instability of alertness, and impulsivity induced by fatigue stressors such as long working hours, night work, chronic sleep restriction, inadequate recovery, and jet lag. Learn more about the PVT
