Physical fitness is closely linked to mental resilience, as it enhances an individual's ability to cope with stress and adversity. Regular exercise contributes to the release of neurotransmitters like serotonin and dopamine, which uplift mood and enhance emotional stability. Moreover, engaging in physical activity can improve cognitive function, making individuals more adept at problem-solving and decision-making under pressure. As a result, physically fit individuals often exhibit greater perseverance and the ability to bounce back from setbacks in various aspects of life, positively affecting overall mental toughness.
