Rachel Keck, MS via Dr. Axe – Pets are a big deal in our culture, and that’s a good thing considering there are plenty of health benefits of owning a pet. How do pets help humans? For starters, there’s nothing quite like returning home after a long trip or day at the office and being greeted at the door by your pet. That’s not all. Science suggests that the benefits of owning a pet go far beyond that. For instance, who knew cat purr frequencies induce healing? More on that later… Health Benefits of Owning a Pet Is having a pet good for your health? Yes! And you don’t even have to own a pet to reap the benefits. For instance, the Brooklyn Cat Cafe in New York welcomes people to come and enjoy some delicious treats while hanging out with adoptable cats. Similarly, for dogs, the Dog Cafe was a Los Angeles-based cafe where people can hang with adoptable pups while grabbing a snack, and now there are plenty of dog-friendly places to go. In Hawaii, on the small island of Lanai, there’s a cat sanctuary where people travel from all over the world to hang out with cats and get their cuddle on. Costa Rica is also home to a similar dog sanctuary with more than 1,000 adoptable dogs in every stage of life. The time, effort and love put into both the cafes and sanctuaries demonstrate the value people put on animals. Priceless. Why is it good to have pets? For pet owners and lovers, it comes as no surprise that having a pet is beneficial for health and well-being, including: 1. Social Interaction Social interaction is one of those more obvious health benefits of owning a pet. One underlying mechanism for the positive impact from social and physical contact lies within the dopaminergic pathway in the brain. Following interactions with an animal, such as petting or snuggling, there is an increase in neurotransmitters, specifically dopamine, serotonin and oxytocin, that create a euphoric feeling. A study done at the Veterans Administration Medical Center illustrates another way that animals impact social interaction. In the study, patients sat in either the presence or absence of a dog. Results indicated that social interaction among patients increased following the presence of the dogs. The interaction unleashed a cascade of “feel good” neurotransmitters, increasing the mood, pleasant emotions and overall mental health of individuals. 2. Improved Mood Human and pet interactions, whether through physical contact or through visual stimulation, can create a positive, calming and soothing atmosphere. Physical contact with an animal, through petting or cuddling, activates touch receptors on the skin. These touch receptors then stimulate areas of the brain that are associated with reward centers and cause a cascade of activity resulting in the release of a variety of neurotransmitters. Stimulation of the touch receptors also results in an increase in oxytocin, the love hormone, and a decrease in cortisol levels, the stress hormone. 3. May Boost Heart Health An increase in oxytocin is associated with stress relief due to a decrease in anxiety and blood pressure. A study conducted at the University of Minnesota Stroke Institute in Minneapolis illustrated that pet owners, particularly cat owners, experienced a 30 percent decrease in heart attack or stroke. The human and animal relationship also has been shown to decrease cholesterol and triglyceride levels. The decrease in cortisol, cholesterol and triglyceride levels in conjunction with the increase in oxytocin all contribute to aiding in the health of an individual’s cardiovascular system — therefore decreasing the risk of a heart attack or stroke. 4. Mental Health Booster Just seeing a pet also has profound positive effects. A study at Caltech showed that individual brain cells responded when a person saw an animal but not when they saw another person, place or object. The cells activated upon visual stimulation are found in the amygdala, the region in the brain associated with emotion and fear. Since the cells respond to any type of animal, it’s believed that it may be a leftover ancestral relic involving specialized cells that help the brain respond to danger quickly. In those times, the danger was often animals. Now, these cells are responding to an emotional response evoked by the animal that is often less out of fear and more often due to adoration, once again activating the dopaminergic pathway. It’s due to the activation of this pathway from varying interactions with animals that results in an increase in mood, a decrease in anxiety, improved sleep and an overall improvement of mental health. 5. Anxiety Reducer Several studies illustrate a reduction in anxiety and an increase in sleep due to interactions with animals. In one such study, 230 patients were referred to animal therapeutic sessions. Data was collected prior to and following the animal therapy session with results showing a significant reduction in anxiety follow the session. This study illustrates the significant impact animals have in helping reduce anxiety during times of duress, though more research is needed to understand the underlying mechanism. 6. Better Sleep Another study conducted by the Mayo Clinic illustrated that 41 percent sleep better due to the presence of the pet in bed, while only 20 percent describe a sleep disturbance due to it. This may, in part, be due to the feelings of safety, comfort and the cozy atmosphere that the presence of animals creates. Improvements in sleep lead to a slew of other health benefits, including warding off illness, increased memory, succinct mental processes, a decrease in stress and improvement of mood. 7. Greater Relaxation While the effects that cats and dogs have on humans are similar in many ways, cats have one crucial difference that puts them at an advantage to be more beneficial to humans than dogs. Cats purr. Cat purring occurs during both inhalation and exhalation at a consistent pattern and frequency between 25 and 150 Hz. While purring helps soothe, calm and lull people to sleep with its rhythmic pattern and vibrations, purring has also been shown to occur at frequencies often used in therapies to heal the human body. Studies have shown therapeutic vibrations can aid in bone growth, fracture healing, pain relief, swelling reduction, wound healing, muscle growth/repair and increased mobility of joints at frequencies between 25–150 Hz. Beyond healing an injury, the vibrations caused by a cat purr can lead to changes in brain activity. A noninvasive study was done to measure the neurological response of the high-frequency sound and vibration (16). An electroencephalography test showed increased neuronal activity within the occipital region (visual perception) during high-frequency stimulation, along with increased cerebral flow within the brain stem (region of the brain crucial for regulation of the central nervous system, cardiac function, breathing, heart and the left thalamus that regulates consciousness). Purring is often compared to rhythmic chanting, which is used in different cultures to aid in a healing process or to create a meditative or calm state. Rhythmic sounds, such as chanting or purring, cause a phenomenon known as brainwave entrainment. Brainwave entrainment is a process in which an individual’s brainwave frequency becomes synchronized with a periodic stimulus (vibration, sound, light). The vibration of the cat purr, in conjunction the sound of the purr, can lull a person into relaxation. One study showed the effects of natural sounds on individuals. Individuals were exposed to sounds found within nature, and cardiac monitoring along with imaging techniques was used to determine brain activity during tasks following noise exposure. The results showed that natural sounds, such as that made from a cat, were associated with a decrease in the sympathetic response (the fight or flight response to a situation) and an increase in the parasympathetic response. The parasympathetic response is responsible for the body’s ability to relax. Therefore, one is able to deduce that the vibration and sound of a purr from the cat has the ability to aid in healing as well as cause relaxation in humans. Despite the differences, pet owners benefit from the interactions they have with their pets and with other individuals due to their pets. Interactions with both animals and humans result in a release of the neurotransmitters dopamine, serotonin, and oxytocin in the brain. The release of these neurotransmitters activates the dopaminergic “reward” pathway in the brain, causing a feeling of happiness. The increase in oxytocin, the love hormone, causes a decrease in the stress hormone cortisol. The effect of all this together is an increase in mood, better sleep, a decrease in blood pressure and a more relaxed feeling. All pets are created equal and are very similar in the beneficial, symbiotic relationship they have with humans … except for cats, whose purr sets them apart from the rest of the animal pack. The purr of a cat has also been compared to rhythmic chanting and has the ability to relax someone to a state comparable to post-meditation. The rhythm and vibration of the purr, much like chanting and even music, can have a brainwave entrainment effect. There is the added benefit of potentially moving the body more when you have a pet, such as walking a dog or playing with a cat. This can encourage people to get up and move around instead of remaining sedentary all day. Even with all this knowledge, more research is needed to understand fully how animals — and especially the purr of cats — affect the central nervous system. With this knowledge, therapies could evolve in conjunction with conventional medicine to help individuals with certain mental health issues and the elderly. Final Thoughts The health benefits of owning a pet range from improving social interaction and mental health to reducing the risk of heart attack or stroke. Health benefits of both dogs and cats are noted in the literature, but cats seem to have an edge due to the healing frequency of purrs. Other health benefits of owning a pet include reducing cortisol levels and the fight or flight response, decreases in anxiety and depression, and more. To read the original article click here.

Michigan State University via Newswise – Since first hearing about the COVID-19 outbreak in China, media outlets around the world have reported on strains of the virus originating in animals, on pets testing positive for the virus and most recently, on a tiger testing positive for COVID-19 at the Bronx Zoo. Annette O’Connor – chairperson of the Department of Large Animal Clinical Sciences and professor of Epidemiology at Michigan State University’s College of Veterinary Medicine – says that there are seven different types of coronaviruses and that the Centers for Disease Control doesn’t believe the COVID-19 strain can be transmitted to domestic animals. However, O’Connor explains that since COVID-19 is a new virus, it’s critical for humans to take extra precautions around animals and pets since there isn’t a wealth of research about the virus. O’Connor answers common questions related to COVID-19 and pets: Can My Pets Get Sick from COVID-19? At this time, we have very limited information about animals and COVID-19 because it is too new of a virus. However, if pets do get sick, we would expect them to have signs such as diarrhea, vomiting or respiratory problems, like trouble breathing. If you are concerned about your pet, you should do what you would usually do: isolate them and contact your veterinarian. Am I at Risk for Catching COVID-19 From an Animal? The transmission we see currently see of COVID-19 is human-to-human transmission. We do continue to see rare reports of cats and dogs that live with COVID-infected patients being infected. To date, we have no evidence that owners can “catch” the virus from cats or dogs because we have no evidence that naturally infected cats and dogs shed the virus. However, as this is a very new virus, pet owners need to continue to follow routine practices for pet hygiene recommended by the American Veterinary Medical Association. These guidelines include washing your hands after petting animals, avoiding touching your face, don’t kiss your pet, and don’t share dishes, drinking glasses, cups, eating utensils, towels or bedding with other people or pets. So what about the tiger at the Bronx zoo who tested positive? The detection of the virus that causes COVID-19 in the tiger is interesting, because it appears to be an example of the transmission from humans to tiger – a very rare event. This finding has highlighted the concern for our wild animal populations, and staff at zoos have adopted practices that will protect these valuable populations. If I Have – or Someone I Know Has – COVID-19, Can My Pet Catch It? If an owner is ill with COVID-19, as suggested by the CDC, they should isolate themselves from the pets and have another household member care for them. If isolation of the pet isn’t possible, continue to use frequent hand washing and avoid touching your face. Also remember: if your pet requires veterinary care, make sure you inform your veterinarian that you or a household member is ill with COVID-19. That information will allow your veterinarian to take adequate precautions. Can My Pets “Catch” the Virus that Causes COVID-19 from Other Pets? There is evidence that cats can catch COVID-19 from other cats – but there is only a small amount of evidence at this point. The largest study we have only involved 102 cats from Wuhan, China; of the 102 tested, only 11 had antibodies to COVID-19. None had evidence of the virus, so they were probably infected some time ago. In that study we also don’t know how the cats became infected, perhaps they were infected from humans, or maybe cat-to-cat transmission does occur. We need to wait for more data.
