Interacting with animals has been shown to decrease levels of cortisol (a stress-related hormone) and lower blood pressure. Other studies have found that animals can reduce loneliness, increase feelings of social support, and boost your mood. For example, researchers are looking into how animals might influence child development.

Animals can serve as a source of comfort and support. Therapy dogs are especially good at this. They’re sometimes brought into hospitals or nursing homes to help reduce patients’ stress and anxiety. Dogs are very present, if someone is struggling with something, they know how to sit there and be loving.

Caring for an animal can help children grow up more secure and active. Pets also provide valuable companionship for older adults. Perhaps most importantly, though, a pet can add real joy and unconditional love to your life.

If you don’t have the time, money, or ability to own a pet full-time, there are still ways you can experience the health benefits of being around animals. You can ask to walk a neighbor’s dog, for example, or volunteer at an animal shelter. Most animal shelters or rescue groups welcome volunteers to help care for homeless pets or assist at adoption events. You’ll not only be helping yourself, but also helping to socialize and exercise the animals, making them more adoptable.
