¿El apego humano-perro aumenta la resiliencia y la resistencia a la COVID-19? Un enfoque biopsicosocial y una investigación a futuro




Palabras clave:

apego, canis lupus familiaris, inmunidad cruzada, oxitocina, pandemia


Este artículo es una propuesta biopsicosocial sobre la mejora de la resiliencia a enfermedades, incluida la COVID-19, debido al apego afectivo entre humanos y perros. La resiliencia se refiere a la capacidad humana física y emocional de responder positivamente a los eventos adversos, como las enfermedades. Recientemente, algunos autores han propuesto hipótesis independientes sobre el papel de la oxitocina (OT) y la inmunidad cruzada para aumentar la resiliencia y la respuesta frente a la COVID-19. Aquí se extiende esa hipótesis al campo biopsicosocial, incluyendo los bien conocidos beneficios del apego afectivo humano-perro sobre la salud humana. Se propone que las relaciones de afecto fuerte y recíproco entre humanos y perros pueden aumentar la resiliencia a la COVID-19, debido al papel de la OT en la respuesta inmune, sumando inmunidad cruzada. Otros beneficios como amortiguar el efecto de las emociones, la comodidad mental y el alivio del estrés son funciones complementarias de los perros en la salud humana y viceversa.
