The NIH article "The Power of Pets" explores the health benefits of human-animal interactions, highlighting that pets can decrease stress, improve heart health, and aid children's emotional and social development. Interacting with animals has been shown to lower cortisol levels and blood pressure, reduce loneliness, enhance social support, and elevate mood. Therapy animals, particularly dogs, are noted for providing comfort and support in settings like hospitals and nursing homes, helping to alleviate patients' stress and anxiety. The article also discusses ongoing research into the safety and efficacy of animal-assisted interventions, especially concerning potential germ transmission in clinical environments.Regarding brain health and cognitive performance, the article suggests that the companionship of pets can mitigate stress and loneliness, factors that negatively impact cognitive function. Engaging with pets may promote mindfulness and emotional regulation, contributing to overall mental well-being. However, while the article provides insights into the positive effects of pet ownership, it does not offer specific lifestyle recommendations for improving brain health. Given the National Institutes of Health's authoritative position and the evidence presented, the information is credible, though further research is needed to establish definitive guidelines.
