Sport improves mood for several reasons:

1. Release of endorphins: Physical activity stimulates the release of endorphins, which are called “happy hormones.” This leads to improved mood and reduced feelings of stress.

2. Reduce Stress and Anxiety: Regular exercise helps reduce stress and anxiety. Physical activity helps you relax and cope with negative emotions.

3. Improved self-esteem: Achievement in sports can improve self-esteem and self-confidence. This can have a positive effect on your mood.

4. Social interaction: Participation in sporting events, team games or group training promotes social interaction, which affects psychological well-being.

5. Improved sleep: Regular physical activity can help improve sleep quality, which in turn promotes a good mood.

6. Developing Discipline: Sports require constant practice and self-discipline, which can lead to the development of positive characteristics and therefore an improvement in mood.

7. Distraction from problems: Exercising can temporarily distract you from everyday problems and negative thoughts, which promotes a more positive mood.

8. Improved physical health: Increasing physical activity contributes to overall improved physical health, which is important for psychological well-being.

Remember, it's important to choose a sport you enjoy to reap the maximum benefits for your mood and mental health.
