How does regular physical activity benefit health?

Regular physical activity increases energy levels through several mechanisms. Engaging in exercise helps improve cardiovascular health, enhances muscle strength, and boosts overall stamina. When the body is physically active, it becomes more efficient at using oxygen, which can lead to greater energy production.

Moreover, regular exercise promotes the release of endorphins, often referred to as "feel-good" hormones, which can elevate mood and reduce feelings of fatigue. Over time, those who maintain a consistent exercise routine often report higher levels of alertness and vitality in their daily activities.

In contrast, options that mention decreases in muscle mass, reduced sleep quality, or the absence of significant effects do not reflect the established benefits of physical activity. Instead, regular exercise is widely recognized for its positive impact on both physical and mental health, making the increase in energy a fundamental advantage of staying active.
