Scratch that itch: Why focusing on inflammation can reduce symptoms

A recent study from Bar-Ilan University's Azrieli Faculty of Medicine in Israel reveals that focusing attention on areas of inflammation can alter the body's inflammatory response. Researchers discovered that when participants voluntarily concentrated on sensations from a localized area of inflammation in their arm, the inflammatory reaction was less severe and recovered more rapidly than when they diverted their attention.

The study, published in Nature Human Behaviour, involved 57 healthy volunteers who experienced a temporary skin inflammation. They were instructed either to focus on the inflamed area or shift their attention elsewhere. The researchers observed the inflammatory response for 20 minutes, alongside monitoring heart rate, skin temperature, and nervous system activity.

Nearly 90% of participants experienced a smaller inflammatory reaction when directed their attention to the affected area, changes occurring within minutes. Dr Liron Rozenkrantz, a researcher, stated that directing attention towards the inflamed area not only influenced the participants' experience but also altered the inflammatory response itself.

The study's lead researcher, Dr Nofar Mizrachi, in collaboration with Prof Menachem Rottem, a clinical immunologist, suggested that the brain's prioritization of bodily signals could impact how the body regulates itself. The implications of these findings remain to be seen, particularly regarding their applicability to chronic inflammation, autoimmune diseases, wound healing, or other conditions.

The next step for the team is to uncover the specific brain and immune pathways involved and determine if similar effects occur in other organ networks.
