The starting point of Human-Animal Interaction began during the nineteen-eighties when it became a field of study. In the past ten years’ human-animal interaction influenced human-animal assistance and became accepted that it has positive effects on humans, (Beetz, Andrea, 2012). Today, animal-assisted interventions for children and adults with or without mental health problems is positively acknowledge. Many studies show physiological effects of human-animal interaction. Which is associated with psychological process integrating with the psychophysiological effects of human-animal interactions backed up by the studies. There are many effects of human-animal interaction. Specifically, there are negative and positive effects. The negative effects hence little to none. Nevertheless, the positive effects have helped children with autism to elderly residents or patients. …show more content…
The different parameters that are affected is the heart rate variability (HRV), heart rate and blood pressure. While walking with a dog, ones’ heart rate was significantly higher than when walking alone. Generally, higher heart rate variability indicates a relax state and an increase of para-sympatric activity, (Motooka et al. (2008). Handlin et al. (2011), showed that stroking one’s own dog for just three minutes led to decreased heart rates fifty-five minutes later in female dog owners. While no such response was observed in a controlled group not petting a dog. Allen et al. (2002), investigated the effect of two stressors in married couples, other in the presence of a friend, their own pets, or the spouse. In the presence of their pets, pet owners showed significantly lower heart rates and blood pressure before the task, less increased reaction toward the stressor and faster recovery, than the non-pet owning participants. All of these anti-stress parameters are positively effected by human-animal
