How to Use Positive Self-Talk for Better Mental Health.
Self-talk is basically the conversations you have with yourself in your mind. It reflects your beliefs, thoughts, and feelings, and can be either uplifting or discouraging. If you’re naturally optimistic, your inner dialogue is probably more positive, but if you lean towards pessimism, it might be more negative. Shifting to positive self-talk is a powerful tool for managing stress and boosting your overall health. Studies show that having a positive mindset can improve your quality of life.
