Cardiovascular exercise improves mood through the release of endogenous opioids, such as endorphins and cannabinoids, which contribute to feelings of happiness and stress alleviation. Regular aerobic activity can lead to long-term improvements in emotional well-being and resilience against anxiety and depression. Enhanced blood circulation during these exercises increases energy levels and cognitive clarity. Furthermore, group cardiovascular activities, like running clubs or cycling classes, provide social interactions, which further enhance mood and promote a sense of community.
