How Purring Cats Can Improve Your Health

Meet “Moo”—my daughter Tupelo’s beloved new kitten.


Whenever she cradles him, he happily purrs while Tupelo relaxes. These past few days have been the most relaxed I’ve seen her in months!

And it makes sense, according to the science. Interestingly, there are a number of studies pointing to the healing powers of cats—especially the sound of their purring.

Cats have been shown to provide therapeutic effects for heart health, longevity, and even bone and tissue healing!

In this issue of Sound Health, you’ll learn all about the healing power of a purr and why a furry addition to your family could literally be a life saver.

Cats slash heart attack risk up to 40 percent

Heart disease is the leading cause of death worldwide, claiming nearly 17.9 million lives each year.

But according to a 2009 study from the University of Minnesota, owning a cat may significantly lower your risk for developing this far too common disease.

The study was conducted over a span of 20-years years and included nearly 4,500 participants between the ages of 30 to 75. Nearly half the participants owned a cat at the time of the study or had previously owned a cat at some point in their lives. The other half had never owned a cat.

Researchers found that compared to cat owners, those who never owned a cat had:

  • 40 percent higher risk of suffering a heart attack
  • 30 percent greater risk of dying from some form of heart disease.

The researchers attribute the cat owners’ improved health markers to previous studies showing that pet ownership reduces stress and lowers blood pressure—two factors that decrease overall heart disease risk.

But the health benefits of cat ownership don’t stop there…

The healing frequencies of a cat purr

There’s also a fascinating connection between the frequency of cat purrs and the healing of broken bones and injured soft tissues.

I realize this may sound a little “out there,” but according to the research, the sound frequency of purring offers quite the therapeutic healing benefit.

According to Scientific American, the frequency of a cat’s purring ranges between 25 and 150 hertz (Hz). This is the same range of frequencies used by the ultrasound devices doctors have been using to fuse broken bones, improve bone mass loss, and even heal wounds.

A 2015 study found that this sound frequency therapy works to improve bone strength by increasing bone formation. This is done with a very low sound frequency of 30 Hz—just above what the human ear is able to hear.

In another 2015 study, 116 women suffering from osteoporosis received 30 Hz of vibration for 10 minutes for five days a week. This therapy helped increase bone mineral density by an average of 4.3 percent.

Another 2014 study highlights how a 60 Hz frequency stimulated the growth of new blood vessels in hard-to-heal wounds like diabetic ulcers. And while these doctors use electronic devices to create these frequencies, our furry friends can do it, too.


Tapping into your own healing frequencies.

Cat’s aren’t the only ones with the ability to soothe themselves with sound…

You can, too!

You’re built with the ability to generate your own healing frequencies. In order to enjoy their healing benefits, all you need are a few sound-based techniques.

I detail a few of my favorites here and here.

But the best way to get the most powerful health benefits from self-generated sound is to put these techniques into action on a regular basis.

Fortunately, there’s an easy-to-use tool to help you develop a consistent practice.

It’s called the Inner Sound Method. Every week, I’ll send you a 10-minute video tutorial, designed to help you jumpstart and maintain your own sound healing routine—all while improving your day-to-day life and improving your long-term health.

It’s completely different from anything I’ve ever done. Think of it as having regular, private, guided sessions with me, for as long as you need!

Oh, and one more thing: Moo told me he wants you to, “stay safe, be kind, and take care of one another.”
