New study suggests touch is a key ingredient in dogs' stress-buffering power

Key Points:

• A study published in Biological Psychology found that dog owners who physically petted their dogs after a stressful mental test exhibited calmer brain and heart responses during a subsequent stress challenge, while mere eye contact or talking without touch did not provide the same benefit.
• The research involved 64 dog owners undergoing two stress tests with recovery phases; physical touch with their dog during recovery did not speed immediate stress recovery but served as a protective buffer, reducing physiological stress responses in the second test.
• Physiological measures including brain alpha and beta waves, heart rate, and heart rate variability showed that touch with a pet lowered biological stress reactivity, though participants' self-reported stress levels did not consistently align with these measures.
• The study highlights the importance of physical touch in human-animal interactions for stress buffering, suggesting that stroking a dog’s fur stimulates nerve fibers that send calming signals to the brain, but notes the need for further research to confirm findings and explore mechanisms.
• Researchers emphasize the mutual comfort of both human and animal during interactions, caution about generalizing findings beyond White European dog owners, and call for future studies on diverse populations, different stressors, and interactions with unfamiliar animals.
