Useful life lessons for health and well-being: adults' reflections of childhood experiences illuminate the phenomenon of the inner child.

The participants' experiences of events during childhood were illuminating the phenomenon of the inner child as promoting or hindering health and well-being and impact human adaptation throughout life. Our findings indicate that the participants learned useful life lessons suggesting that experiences during childhood can help us to adapt across the life span and over generations, and this is the essence of the inner child. Our findings also contribute to the health literacy discussion and detail how knowledge and action competency is developed in mental, social and existential dimensions of health and well-being.
