Prof. Benjamin Murphy, Ph.D.Scientific evidence of the effectiveness of animal therapy exists in more than 200 peer-reviewed studies providing measurable biological change. As evidenced by research into measurable biological data, animal therapy yields physiological improvements, including decreased cortisol levels and lower blood pressure, resulting from the experience with animals. These indicators or biological markers provide a valid measure of the therapeutic effect across various populations that have been studied.
Physiological Markers
- Cortisol reduction averages 10-20% across clinical studies
- Blood pressure decreases 5-10 mmHg during sessions
- Heart rate variability patterns shift toward healthier coherence
Psychological Improvements
- Anxiety scores decrease 15-30% in standardized assessments
- Depression scales show mood elevation lasting 4-6 hours
- Social engagement increases 40% in group settings
Longitudinal Outcomes
- 6-month programs show sustained immune system enhancement
- Children maintain social skill gains 3 months post-therapy
- Elderly participants report reduced medication needs
Research methodologies include controlled clinical trials, which compare treatment groups with control groups to assess the effectiveness of treatments. Facts relating to salivary cortisol, blood pressure, Mood, and behavioral observations are measured before, during, and after the sessions. Has been completed. This method demonstrates both immediate and cumulative effects over time.
Studies in neuroscience link changes in brain activity to interactions between animals. For example, MRI scans reveal increased activity in the prefrontal cortex related to emotional regulation. There are substantial increases in endorphins and oxytocin, which contribute to a natural elevation in mood. These mechanisms confirm the documented psychological benefits that have been found.
The quality of evidence varies depending on program structure and length. Brief interactions demonstrate short-term stress reduction, whereas structures that last 8-12 weeks exhibit long-term change. Evidence is further strengthened when results are shown under the leadership of a trained professional; this helps ensure that measurable outcomes remain consistent across various contexts or populations.
