What does non-productive activity likely indicate at elevated heart rates?

Non-productive activity at elevated heart rates is indicative of potential stress overload. Elevated heart rates can be a physiological response to stress, which may impair a person's ability to focus and perform tasks efficiently. When individuals experience stress, their attention can become scattered, leading to activities that do not contribute meaningfully to their goals or responsibilities. This misdirected focus may manifest as engaging in activities that are not constructive, reflecting an overload of stress rather than effective coping or heightened productivity.

In contrast, options suggesting effective coping strategies, heightened alertness, or increased productivity would typically be associated with a well-managed response to stress rather than a sign of being overwhelmed. Therefore, the presence of non-productive activity alongside elevated heart rates serves as a warning sign that an individual may be struggling to cope with stress, ultimately leading to decreased overall effectiveness.
