What physical measure is essential to combat fatigue?

Regular exercise is essential for combating fatigue as it boosts energy levels, enhances mood, and improves overall physical and mental health. Engaging in physical activity increases blood circulation, which allows for more oxygen and nutrients to reach the body's tissues, helping to fight feelings of tiredness. Moreover, exercise promotes the release of endorphins, which are natural mood lifters, and can lead to improved sleep quality.

In contrast, the other options can contribute to increased fatigue. Inadequate hydration can lead to dehydration, which causes tiredness and lethargy. Excessive screen time often leads to eye fatigue and can disrupt sleep patterns, further contributing to feelings of exhaustion. Skipping meals deprives the body of necessary nutrients and energy, ultimately leading to fatigue. Regular exercise, on the other hand, provides a positive framework for maintaining energy levels and overall health, making it a vital strategy in managing fatigue.
