What is an example of a fatigue countermeasure?

The correct choice highlights social interaction as a fatigue countermeasure because engaging socially can divert attention away from feelings of fatigue and help rejuvenate mental alertness. Interaction with others may stimulate cognitive function and emotional well-being, providing a psychological boost that can combat the effects of fatigue. It can lead to increased motivation and energy levels, which are crucial when trying to perform tasks while tired.

In contrast, while relaxation techniques may also help in managing stress, they might not necessarily counteract fatigue effectively, as they can sometimes lead to further relaxation rather than re-energization. Reducing caffeine intake typically aims to alleviate potential negative effects of excessive consumption but does not directly address fatigue. Intensive napping, while providing temporary relief from fatigue, may not be practical in a work setting and could lead to sleep inertia, which can impair performance instead of enhancing it.
