Today’s world is more connected—and more mentally strained—than ever. Rates of anxiety and depression are at an all-time high, with the World Health Organization reporting that nearly 1 billion people globally live with a mental disorder. In the U.S., over 42 million adults struggle with anxiety, and loneliness has become so widespread that the Surgeon General declared it a public health crisis (source).
As people search for ways to manage their mental health, many are turning to a comforting, loyal source of support: pets. Whether it’s the calm of a cat’s purr or the joy of a dog’s tail wag, pets offer more than affection—they provide real psychological benefits backed by science.
From reducing stress hormones to boosting mood and combating loneliness, pet ownership has been shown to have powerful effects on mental well-being. In this blog, we’ll explore five science-backed ways that pets help improve mental health—and why they may be one of the most underrated tools for emotional wellness..
1. Pets Help Reduce Stress and Anxiety Naturally
It’s not just in your head—interacting with pets really does lower your stress levels.
Scientific research shows that petting animals can lower cortisol (the body’s primary stress hormone) and raise serotonin and oxytocin—chemicals that promote relaxation and happiness.
👉 In one study published in Frontiers in Psychology, participants who spent just 10 minutes petting a dog or cat had a significant drop in cortisol levels compared to those who didn’t interact with animals (source).
The soothing nature of pets—whether it’s a dog’s loyalty or a cat’s rhythmic purring—offers a calming effect on the nervous system and can reduce symptoms of anxiety.
Pro tip: Start your morning or end your day with 5 minutes of intentional pet interaction—it’s a simple, natural stress reliever.
2. Pets Can Boost Mood and Ease Symptoms of Depression
Feel down? Your furry friend might be able to help.
A report from the Human Animal Bond Research Institute (HABRI) found that 74% of pet owners said their pets improved their mental health. For many, pets provide a sense of purpose, routine, and joy—even on difficult days (HABRI study).
Pets are known to increase dopamine and endorphins, both feel-good neurotransmitters associated with pleasure, focus, and motivation. When you’re feeling low, simply watching your pet be their quirky, adorable self can spark a laugh—and a much-needed emotional lift.
According to a survey by Talker Research, 95% of pet owners say their pets improve their mental health every single day.
3. They Provide Routine, Structure, and Daily Purpose
One of the more underrated benefits of pet ownership is the sense of daily structure it naturally creates. Feeding schedules, walking routines, playtime, and grooming—all contribute to a consistent rhythm that can be especially helpful for those struggling with depression or ADHD.
The American Psychiatric Association notes that routine helps regulate sleep, mood, and focus, and animals help enforce that structure with their needs (source).
🐕 Your dog doesn’t care if you’re tired or sad—they still need a walk. This small obligation can nudge you toward movement, sunlight, and mental clarity.
4. They Combat Loneliness and Social Isolation
The emotional impact of loneliness is often underestimated, but it’s linked to increased risk of depression, anxiety, and even early death, according to the CDC.
Pets offer a unique form of nonjudgmental companionship that fills emotional gaps, especially for people who live alone or are isolated due to physical or mental health challenges.
In fact, during COVID-19 lockdowns, pet adoptions surged globally as people sought comfort and connection. A study in BMC Public Health found that pet owners experienced less loneliness and higher perceived social support during the pandemic (source).
Even something as simple as walking your dog can lead to casual conversations and new social interactions—both of which are great for mental health.
5. Unconditional Love That Builds Emotional Security
Perhaps the most powerful benefit of pet ownership is unconditional love. Pets don’t judge, hold grudges, or expect perfection. They accept you in all your emotional states—happy, anxious, overwhelmed, or heartbroken.
This emotional security has tangible mental health benefits. Studies show that the bond between humans and pets promotes emotional regulation and self-esteem, especially in individuals with trauma or attachment issues.
Emotional Support Animals (ESAs) are often recommended for people with PTSD, anxiety disorders, and depression, and the U.S. Department of Veterans Affairs supports therapy dog programs for veterans dealing with mental health struggles (VA resource).
