Which benefit is NOT commonly associated with regular exercise?

Regular exercise is widely recognized for numerous health benefits, and among these, a temporary increase in stress levels is not considered a typical benefit. In fact, regular physical activity is generally associated with reducing stress and improving mental health. Exercise has been shown to promote the release of endorphins, often referred to as "feel-good" hormones, which contribute to decreased feelings of stress and anxiety.

On the other hand, the other benefits mentioned—reduced risk of disease, delayed aging, and increased longevity—are well-documented outcomes of consistent exercise. Engaging in regular physical activity helps enhance cardiovascular health, strengthen the immune system, and can contribute to a lower risk of chronic diseases such as diabetes and heart disease. Additionally, exercise supports healthy aging by maintaining muscle mass, flexibility, and mental sharpness. Ultimately, these factors collectively lead to a longer, healthier life, as regular exercise has been consistently linked to increased longevity.
