Which of the following is an example of good health behavior?

Engaging in regular physical activity is a prime example of good health behavior as it provides numerous benefits for both physical and mental well-being. Regular exercise helps to maintain a healthy weight, reduces the risk of chronic diseases such as heart disease and diabetes, and contributes to overall cardiovascular health. Additionally, physical activity can improve mood, reduce stress, and enhance overall quality of life.

In contrast, the other options illustrate behaviors that could negatively impact health. Consuming fast food regularly typically leads to poor nutrition, smoking daily poses significant risks to lung health and increases the likelihood of various diseases, while staying awake for extended periods can disrupt sleep patterns and impair cognitive function. By choosing regular physical activity, individuals are taking proactive steps toward a healthier lifestyle.
