Dog
The therapeutic deployment of dogs has achieved clinical validation across multiple domains. Therapy dogs reduce anxiety in hospital patients by 24 percent according to research published in the Journal of Alternative and Complementary Medicine. Dogs assist veterans with PTSD, provide grounding for individuals experiencing panic disorders, and offer non-judgmental companionship to those receiving mental health treatment.
The mechanisms appear to involve both the tactile sensation of contact and the social facilitation dogs provide. A therapy dog creates a bridge between isolated individuals and social interaction, lowering the barriers that mental health conditions often erect.
Silence
Silence forms the foundation of contemplative therapeutic traditions spanning millennia. Vipassana meditation retreats prescribe ten days of complete silence as transformative practice. Research from UCLA demonstrates that regular silent meditation practitioners exhibit greater cortical thickness in brain regions associated with attention and interoception.
The therapeutic application of silence requires, however, that the individual tolerates it. Many cannot. Researchers at the University of Virginia found that 67 percent of men and 25 percent of women would rather administer electric shocks to themselves than sit alone with their thoughts in silence for fifteen minutes. Silence offers profound benefits to those who can endure it.
VERDICT
Dogs deliver therapeutic benefit regardless of the recipient's psychological preparedness. Silence demands a capacity for introspection that many have not developed.
