How does increasing cardiorespiratory fitness affect stress on your body?

Increasing cardiorespiratory fitness leads to a reduction in overall stress on the body. This improvement in fitness enhances the efficiency of the heart and lungs, allowing the body to utilize oxygen more effectively during physical activity. As a result, regular aerobic exercise strengthens the cardiovascular system and improves recovery from exertion, which can lead to lower resting heart rates and blood pressure.

Furthermore, engaging in activities that enhance cardiorespiratory fitness stimulates the release of endorphins and other neurotransmitters that help improve mood and promote relaxation. This contributes to a more resilient response to stressors, thereby rightfully decreasing overall stress levels experienced in both physical and mental contexts. In addition, improved fitness can lead to better sleep quality, increased energy levels, and enhanced mental well-being, all of which play a crucial role in managing stress effectively.
