What is the field of psychoneuroimmunology (PNI) concerned with?

The field of psychoneuroimmunology (PNI) is primarily concerned with the interplay between psychological processes, the nervous system, and the immune system. It explores how mental states, emotions, and psychological factors can influence bodily functions, particularly immune responses. This discipline underscores the significance of stress, emotions, and behavior on health and illness by investigating the biochemical and biological pathways that link the psyche with immune functioning.

Understanding this connection can lead to insights on how psychological interventions can impact physical health, especially in immune-related conditions. The focus is not just limited to the psychological aspect, as it encompasses the neurological and immunological ramifications, integrating knowledge from multiple disciplines to foster a holistic view of health and well-being.
