Why is mental fitness included in the dimensions of health and fitness in TC 7-22.7?

Mental fitness is included in the dimensions of health and fitness in TC 7-22.7 because it plays a crucial role in overall performance. It encompasses not only cognitive functions such as focus, decision-making, and emotional resilience, but also the ability to cope with stress and maintain motivation. Mental fitness directly influences physical performance, as a strong mental state can lead to better physical conditioning, improved teamwork, and effective leadership. The integration of mental fitness acknowledges that health and fitness are multidimensional, and that mental well-being is just as important as physical health for achieving optimal performance and maintaining a high quality of life.
