Did you know that the frequency of a Cat purring is actually very healing?
Purr frequencies correspond to vibrational/electrical frequencies used in treatment for bone growth/fractures, pain, edema, muscle growth/strain, joint flexibility, dyspnea, and wounds. Domestic cats, servals, ocelots, and pumas produce fundamental, dominant, or strong frequencies at exactly 25 Hz and 50 Hz, the two low frequencies that best promote bone growth/fracture healing [Chen et al., Zhong. Wai Ke Za Zhi. 32, 217–219 (1994)]
Practice Pranayama and Meditation with some purring frequencies in the background for your ASMR healing benefits. Best listened to in headphones and at any volume that activates the physical tingles for you.
