Why do we talk to ourselves in our heads? The mystery of inner speech explained

Inner speech, or self-talk, is a natural cognitive process that helps humans plan, reflect, and regulate emotions. A recent study explored how this internal dialogue, when constructive, aids self-regulation and awareness, but can also lead to distress and reduced self-concept clarity if it becomes self-critical or repetitive. Mindfulness and self-acceptance are key to managing this inner voice.
