"Unfreeze" refers to the process of changing something from a frozen state back to a liquid or usable form. This typically occurs when ice or frozen substances are exposed to warmer temperatures, allowing them to melt. For example, when you take a block of ice out of the freezer, it will gradually unfreeze as it warms up. In a broader context, "unfreeze" can also describe the act of releasing or removing restrictions. In psychology, it may refer to breaking down old habits or beliefs to allow for new growth and change. This concept is often used in change management theories, such as Kurt Lewin's model, which emphasizes the importance of preparing for change.
