🧠¿La atención modula la respuesta inmunitaria?
Distraerse puede reducir la percepción del dolor o el prurito. Sin embargo, un estudio publicado en Nature Human Behaviour sugiere que concentrarse en las sensaciones corporales modifica la inflamación aguda.
En tres experimentos prerregistrados, los investigadores indujeron una reacción cutánea con histamina. Al enfocarse en el área afectada, los participantes presentaron una respuesta aproximadamente 1,5 veces menor y de resolución más rápida que ante estímulos distractores.
Los resultados proceden de personas sanas y de un modelo localizado, por lo que no pueden extrapolarse a enfermedades crónicas, autoinmunes o infecciosas. Aun así, invitan a reconsiderar cómo los procesos cognitivos influyen sobre funciones tradicionalmente consideradas autónomas.
