Exercise has a profoundly positive effect on overall energy levels. Regular physical activity increases cardiovascular fitness, enhances muscle strength, and improves endurance, leading to better overall functionality throughout the day. Engaging in exercise promotes the release of endorphins, which can elevate mood and reduce feelings of fatigue. Over time, consistent physical activity can improve sleep quality, further boosting daytime energy. As a result, individuals who exercise regularly often report feeling more energized and less prone to exhaustion.
