Bar-Ilan study finds paying attention to an inflamed spot makes it calm down faster

Researchers at Bar-Ilan University's Azrieli Faculty of Medicine in Israel reported in Nature Human Behaviour in mid-August 2026 that where people direct their attention can change how strongly their body reacts to inflammation. The work came from the lab of Dr. Liron Rozenkrantz and was led by Dr. Nofar Mizrachi, with clinical immunologist Prof. Menachem Rottem of Emek Medical Center in Afula.

The team ran three preregistered experiments with 57 healthy adults. Each volunteer received a standard skin-prick procedure, of the kind used in allergy testing, that produces a small and temporary patch of redness and swelling. Participants were then asked either to concentrate on the sensations coming from the affected arm or to watch videos that drew their attention elsewhere. Over the next 20 minutes the researchers measured the size of the reaction several times and tracked heart-rate variability, skin temperature and other signs of autonomic nervous system activity.

Almost nine in ten participants had a smaller reaction when they paid attention to the inflamed site. On average the swelling and redness were about one and a half times smaller than when the same people were distracted, and the skin returned to normal faster. The difference appeared within minutes. Because each person was tested under both conditions with the same inflammatory trigger, the design points to attention itself as the cause.

The researchers found two routes for the effect. One depends on sensory signals travelling from the inflamed tissue to the brain. The other is a top-down influence that persisted even when those signals were dulled with a local anaesthetic. Tel Aviv University neuroimmunologist Asya Rolls, who was not involved, praised the study's design in comments to The Times of Israel.

The authors are careful about the limits. The study involved only healthy volunteers and a short-lived, artificially induced reaction, so it does not show that attention training can treat chronic inflammatory or autoimmune disease or speed wound healing. The team next plans to map the specific brain and immune pathways involved.
