Recent “research on frequencies that promote bone growth, fracture healing, pain relief ad relief of breathlessness and inflammation, show that frequencies between 20 Hertz and 150 Hertz are healing frequencies. All cat species have purr frequencies between 20 Hertz and 150 Hertz with the exception of the cheetah.” The cheetah purrs at 25, 50, 100, 125 and 150 Hertz. “This corresponds exactly with the best healing frequencies.”
Lyons notes that the purring of a cat lowers stress — petting a purring cat has a calming effect. It decreases the symptoms of dyspnoea (difficulty in breathing) in cats and humans. It also lowers blood pressure and reduces the risk of heart disease. Cat owners have 40% less risk of having a heart attack.
The healing power of cat purrs is believed to help with infections, swelling and pain, muscle growth and repair, tendon repair and joint mobility.
