Affirmations work by leveraging the principle of neuroplasticity, where our brain's structure and function can be shaped by thoughts and experiences. Repeating positive affirmations can reinforce certain neural pathways, helping to foster a positive mindset. Over time, these repeated positive thoughts can help to challenge and weaken negative beliefs or self-talk, contributing to improved mental well-being. This process is akin to exercising a muscle; the more regularly affirmations are practiced, the stronger and more influential they become in shaping one’s outlook and behaviors.
