What level of stress is recommended for maintaining alertness?

Maintaining alertness typically requires a consistently low level of stress. When stress levels are too high, it can lead to overwhelm and cognitive impairment, which negatively impacts decision-making and situational awareness. Conversely, having no stress or an overly relaxed state can also detract from alertness, resulting in a lack of focus and responsiveness.

A moderate and balanced approach to stress, where there is just enough challenge to keep an individual engaged but not so much that it causes anxiety or a fight-or-flight response, is ideal for achieving optimal alertness and performance. Fluctuating levels of stress may not provide the stability needed for sustained attention, while a high level of stress can cause burnout and fatigue, diminishing overall performance. Therefore, a consistently low level of stress is crucial for keeping alertness at a desirable level.
