Emotional Support Animals (ESAs) have gained recognition for their ability to provide comfort and stability to individuals facing mental health challenges. While they are not service animals and do not require specialized training, ESAs play a vital role in improving emotional well-being. But what is the science behind their effectiveness? Let’s explore how these animals positively impact mental health.

How Emotional Support Animals Help
Research has shown that interaction with animals can have profound psychological and physiological benefits. Here’s how ESAs contribute to mental health improvement:
Reducing Stress and Anxiety
When a person interacts with an ESA, their body releases oxytocin, often called the "love hormone." Oxytocin promotes feelings of bonding and relaxation while lowering cortisol, the stress hormone. This hormonal shift can significantly reduce anxiety and help individuals feel calmer in stressful situations.
Alleviating Symptoms of Depression
The companionship of an ESA can help combat feelings of loneliness and isolation, two major contributors to depression. Studies show that caring for an animal increases dopamine and serotonin levels—neurotransmitters responsible for feelings of happiness and well-being.
Providing Comfort During Emotional Distress
ESAs offer unconditional love and non-judgmental companionship, making them a source of emotional stability. For individuals dealing with PTSD, anxiety disorders, or other mental health challenges, the presence of an ESA can provide a soothing effect during moments of distress.
Encouraging Routine and Responsibility
Taking care of an ESA fosters structure and routine in a person’s life. Daily activities like feeding, grooming, and exercising an animal can provide a sense of purpose and encourage individuals to stay engaged in their daily lives.
Lowering Blood Pressure and Heart Rate
Studies have found that petting or interacting with animals can lead to a decrease in blood pressure and heart rate, helping individuals feel more physically relaxed. This is especially beneficial for those who experience chronic stress or panic attacks.
Scientific Evidence Supporting ESAs
Several scientific studies highlight the benefits of emotional support animals:
A study published in BMC Psychiatry found that animals provide emotional comfort, reduce feelings of loneliness, and act as a coping mechanism for people with mental health conditions.
Research from the National Institute of Child Health and Human Development found that when playing with the family dog, children had higher levels of oxytocin compared to when they played alone with toys.
A study in Brill indicated that U.S. military veterans with PTSD reported having benefited from living with a dog. Respondents indicated that since adopting their dog, they had experienced feeling calmer, less lonely, less depressed, and less worried about their own and their family’s safety. These results suggest that living with a companion dog may help relieve some of the psychological distress associated with PTSD in some veterans.
