What is a common acute benefit of regular physical activity?

Regular physical activity is known to have immediate positive effects on mental health, making improved mood and reduced feelings of anxiety and depression a common acute benefit. Engaging in physical activity leads to the release of endorphins, often referred to as "feel-good" hormones, which can elevate mood and create a sense of well-being. This neurochemical response is particularly beneficial in alleviating stress and anxiety, often resulting in a more relaxed state and improved overall mental health.

While increased muscle mass, increased sleep duration, and higher energy intake can also be associated with regular physical activity, these benefits generally manifest over a longer duration rather than immediately following a session of exercise. Muscle mass increases as a result of consistent strength training over time, sleep duration may improve with routine activity but can vary daily, and energy intake typically relates to dietary choices rather than being an immediate effect of physical activity. Thus, the acute benefit of improved mood and reduced anxiety aligns best with what occurs following exercise.
