On average, most adults can concentrate intently on a task for around 10-15 minutes before their attention begins to wander. However, some tasks may require more or less concentration, and individuals may have varying abilities to maintain focus.
Certain techniques, such as mindfulness meditation or the Pomodoro Technique, can help improve concentration and extend the duration of focused work. Regularly taking short breaks and engaging in activities that promote mental well-being, like exercise and nature walks, can also positively impact attention span.
