Which of the following activities can help improve mental health?

Engaging in physical exercise is widely recognized as a powerful way to improve mental health. Physical activity triggers the release of endorphins, often referred to as "feel-good" hormones, which can enhance mood and reduce feelings of stress, anxiety, and depression. Regular exercise is also linked to better sleep, increased self-esteem, and improved cognitive function, all of which contribute to overall mental well-being.

In contrast, activities like aggressive competition, excessive screen time, and social isolation can negatively impact mental health. Aggressive competition can lead to increased stress and anxiety, while excessive screen time can contribute to feelings of loneliness and disconnection. Social isolation, similarly, can exacerbate feelings of loneliness and depression. Therefore, physical exercise stands out as a beneficial activity that promotes a positive state of mental health.
