What are fatigue countermeasures?

Generally, a countermeasure is an action taken to reduce or avoid the effects of an undesirable condition or situation. In managing fatigue, appropriate countermeasures can help improve alertness, maintain performance, and reduce drowsiness. Taking appropriate countermeasures at appropriate times should be a cornerstone of a fatigue risk management system (FRMS), and understanding more about effective fatigue management is a foundation for better employee well-being overall.
