Mental Health Awareness Month: The Benefits of Animal Companionship

The company of animals – whether as pets or services animals – can have a profound impact on a person’s quality of life and ability to recover from illnesses.

The American Pet Products Association’s Pet Owner Survey found that nearly 70% (or 84.6 million) households in the U.S. own a pet. Of those households, 80% believe their pets bring them happiness and emotional support, 55% believe their pets reduce anxiety and depression, and 66% believe their pets relieve stress.[1]

In general, pet ownership can:

  • Improve cardiovascular health and physical activity[2]
  • Decrease stress and lower blood pressure[3]
  • Reduce loneliness, which can increase the risk of developing chronic health conditions[4]

For those living with mental and physical health conditions, animal companionship can be even more beneficial. In people with cancer, animal-assisted interventions (i.e. therapy, education, activities) play a role in reducing anxiety, depression, and aggression during treatment.[5] For people being treated for HIV, those who own dogs show fewer symptoms of depression and are better at taking medications – likely because of the routines that come with dog ownership.[6]

Service dogs can also make a world of difference to many. People who are hearing impaired showed long-term reductions in depression after getting a service dog.[7] Veterans with PTSD reported decreases in depression, social isolation, anxiety, and alcohol abuse, while also reporting improved sleep and better coping with flashbacks after being paired with service dogs.[8] Service dogs also help lighten the responsibilities of caregivers by assisting those with disabilities to accomplish everyday tasks and alerting to symptoms of chronic health conditions.
