The relationship between cardio fitness and mental health is well-documented. Regular aerobic exercise can boost the production of endorphins, which reduce feelings of stress and anxiety while promoting an overall sense of well-being. Additionally, engaging in cardiovascular activities can improve sleep quality, enhance mood, and bolster cognitive functions, such as memory and focus. Long-term, improved cardiovascular health can lead to increased resilience against mental health issues, contributing to a more balanced and fulfilling lifestyle.
