Why Pets Are So Good for Your Mental Health

You know when you’ve had a truly terrible day? Maybe you get home from work and your brain is buzzing with stressful thoughts, or your mood is in the gutter because you got into a fight with your partner. But as soon as you open that door and your beloved pet runs over to greet you with a whine, or a purr, and the look of love in their eyes, somehow, you just feel a little better.

As it turns out, behind that little mood shift you feel in the company of your pet is a pretty solid body of research. Our furry friends are sweet and lovable, yes. But science shows that animals may meaningfully support our mental health. Here are a few of the ways that happens.

Pets Help Reduce Loneliness

Let’s start with the most obvious way pets may help us feel better: Companionship. They’re simply another living being, another heartbeat in the room with you, somebody that’s always around, even if you live alone or don’t have a robust friend network in the area.

Some research shows that animals offer a sense of connection and emotional closeness that buffers against isolation and feelings of loneliness. Pet ownership has been associated with lower levels of loneliness and social isolation as well as lower rates of depression and anxiety.

Plus, there’s something uniquely soothing and comforting about being around a creature that is not going to evaluate, judge, or start a fight with you. Pets don’t care if you answered that email, made a questionable life decision, or left a pile of dirty dishes in the sink (again). They are, generally speaking, just happy you’re there.

No, animals aren’t the best conversationalists. They aren’t going to get into the meaning of life over coffee, shower you with compliments, or give you advice around whatever challenges you’re going through, but maybe that’s okay. Our pets provide us with something else that’s actually quite precious: An ever-present source of unconditional love and affection that’s more steady and refreshingly simple than most of our human relationships.

Animals May Calm Your Brain and Body

If petting an animal instantly makes you feel better, that’s not just your imagination. Pet ownership has been associated with improved stress management and psychological well-being. Some fascinating research illuminates the very real biology underpinning those links, including positive effects on our hormones, brains, and nervous systems triggered by spending time with furry friends.

One study found that when people pet their cats, their emotional arousal and parasympathetic activity (responsible for the “fight or flight” or stress response) decreases. Another study shows that when people pet their dogs, their levels of cortisol (the primary stress hormone) drop, while levels of oxytocin (associated with love, bonding, and a sense of safety) rise. Additional research suggests that interacting with a dog can stimulate an area of the brain called the prefrontal cortex, which plays a role in emotional regulation.

Animals may also help us calm our minds and bodies in less tangible or measurable ways. For instance, dogs may encourage us to practice mindfulness, which has been associated with stress relief and emotional regulation. Think of how immersed a dog is by the smells in the yard, or the sheer joy of chasing a tennis ball. Or the fact that your cat is never ruminating in the past or worried about tomorrow. They’re simply in this place, in this moment. Being around such completely present beings can encourage us to be more present ourselves.

Pets Support Routine, Purpose, and Healthy Habits

Caring for a pet can also promote a daily structure and sense of responsibility that support overall well-being.

Animals need the same things at roughly the same times, every single day: food, walks, potty trips, litter boxes cleaned. That consistent responsibility helps create a built-in rhythm to your day, which may serve as a stabilizing or centering force especially when you’re feeling off, overwhelmed, or stressed. Feeding your fish in the morning or taking your dog for an evening walk can become a small anchoring ritual of sorts, something you do no matter what.

There’s also the unmistakable sense of purpose that comes with caring for another living being. This creature relies heavily on you. Showing up for them, again and again, means everything to them. And on days when you feel a little adrift in the world, that can make all the difference. That feeling of being needed can be surprisingly beneficial to your mental health. One study found that along with companionship, pet ownership provided a sense of purpose and meaning to older adults.

Pets can also support positive lifestyle habits in small ways. For instance, some research has found that dog owners tend to get more physical activity, social interaction, and fresh air; which has been associated with improved mood, sleep, and mental health. Animals can also act as little social bridges.

The Bottom Line

Overall, people caring for pets tend to feel less lonely, less stressed, more purposeful, and happier. You certainly don’t need to know anything about the science behind why pets are so good for us to appreciate their company. But knowing how your fur baby’s mere presence can bring some evidence-backed benefits into your life? That may just make you appreciate them even more.
