How much time of the relaxation response can one exercise session generate?

Engaging in exercise has been shown to elicit a relaxation response that can extend beyond the duration of the activity itself.

Exercise contributes to the relaxation response through several mechanisms, including the release of endorphins, reduction of stress hormones, and improvement of overall mood and energy levels. Research indicates that a single session of moderate-intensity exercise can produce an optimal value of relaxation that may last for approximately two hours afterward. This extended benefit makes exercise an effective strategy for managing stress and promoting a sense of well-being.

While longer sessions of exercise can certainly lead to more profound or longer-lasting effects, the specific response associated with a standard exercise session typically aligns with the estimation of around two hours, making this the most accurate choice.
