There have been quite a few studies looking at the physiological effect of animal interactions, and they have repeatedly shown positive benefits in terms of lowered stress hormones, lower rates of cardiovascular disease and increased oxytocin levels (associated with feelings of well-being).

A recent Korean study in the journal of PLOS ONE (Public Library of Science) wanted to assess the psychological effects of animal interactions by measuring the brainwave responses in 30 individuals asked to interact with a dog in various different ways – playing, grooming, walking, feeding, etc.

Assessing the emotional effect that animal interactions have on the brain.

Brainwaves were measured using an electro-encephalogram (EEG) during these activities, and because it is understood that different waveforms are produced in different areas of the brain in response to stress levels and various emotional states, it is possible to assess the psychophysiological and emotional effect that animal interactions have on the brain.

The brainwaves during interactions were compared to brainwaves produced in a rested state, and participants were both pet owners and non-pet owners to try to eliminate the bias of a pre-existing affection towards animals.

Of the various interactions measured, walking, playing and physically touching a dog (grooming and massaging) seemed to have the greatest effect on brainwaves associated with reducing stress, emotional stability, concentration and even creativity.

We pet owners and dog lovers may find this study somewhat obvious. It’s not a particularly ground-breaking suggestion that walking and playing with your dog makes you feel happier and less stressed. However, at a time when supposedly 15% of the population are on anti-depressant medications, it makes me think I should be taking Bart for his third walk of the day and then cuddling up with him on the sofa for both of our sakes!
