Growing up with a dog or cat can change you down to a cellular level, researchers at CU Boulder have found.

Research conducted by CU Boulder indicates that growing up with a pet can have lasting effects on the immune system, influencing how the body responds to stress even decades later. The study found that individuals who had pets during childhood showed an increase in specific immune cells that help regulate inflammation.

The findings suggest that exposure to certain microbes through pets can provide protective benefits, especially for those living in urban environments with limited outdoor exposure. This microbial exposure from pets may contribute to a healthier inflammatory response, potentially impacting overall well-being for years.

How pets can impact your stress response, CU Boulder research finds

Well, growing up with a pet can change you down to a cellular level. CU Boulder has been studying how having a pet can mean your immune system develops differently. It's to the point that it impacts how your body reacts to stress. Even decades later, when you're an adult. It turns out that people that grow up with pets have an increase in the type of an immune cell that we have in our that keeps inflammation under control. And so just having a pet. Allows you to have more of these, so it's literally impacting your inflammatory response in your body to stress and to get really specific here. There's certain exposures to microbes that can end up being very protective for you. You can get those exposures when you go outdoors, but if you live in a city, maybe you don't get enough of that. So having a pet can really make a difference in how long you can end up lasting in your body for decades.
