Fatigue significantly impacts a security guard's performance by decreasing alertness and slowing reaction times. When an individual is fatigued, their cognitive functions, such as attention, judgment, and processing speed, are impaired. This can result in missed details, slower responses to situations, and an overall reduction in the ability to effectively monitor their surroundings or respond to potential threats.

Fatigue can stem from various factors, including long shifts, inadequate rest, and high-stress levels, all of which contribute to a diminished state of alertness. This decreased capacity can lead to serious consequences, especially in security roles where quick decision-making and responsiveness are critical for ensuring safety and security.

In contrast, the other choices do not accurately reflect the negative consequences of fatigue on performance. Some incorrectly suggest that fatigue might enhance alertness or vigilance, which contradicts the well-documented effects of tiredness on both mental and physical performance.
