Spontaneous healing refers to the unexpected recovery from an illness or injury without conventional medical treatment. This phenomenon can occur in various conditions, including cancer, autoimmune diseases, and chronic pain. Researchers study these cases to understand the underlying mechanisms that may contribute to such recoveries, including the body's natural healing processes and psychological factors. Factors influencing spontaneous healing may include mind-body connection, placebo effect, and individual resilience. While spontaneous healing is not fully understood, it highlights the complexity of health and the potential for the body to heal itself under certain circumstances. Further research aims to uncover insights that could enhance medical treatments.
