Which factor is essential for a child's good health?

A lifestyle that includes physical activity is essential for a child's good health because it plays a crucial role in their physical, mental, and emotional development. Regular physical activity helps children maintain a healthy weight, strengthens their muscles and bones, and improves cardiovascular fitness. It also contributes to better mood and sleep patterns, while reducing anxiety and symptoms of depression. Engaging in physical activity can also enhance cognitive functions and improve concentration, which is beneficial for academic performance.

In contrast, high levels of screen time can lead to sedentary behavior, which is linked to negative health outcomes such as obesity and poor mental health. Consistent emotional support from peers is important but is more related to social and emotional well-being rather than direct health outcomes. While participation in multiple extracurricular activities can support well-rounded development, it does not necessarily guarantee physical health if those activities are not physically engaging. Ultimately, the integration of regular physical activity into a child's lifestyle is fundamental for fostering healthy growth and development.
