A cat’s purr is one of the most comforting sounds in nature, but it serves a biological function beyond just showing happiness. Scientists have discovered that the frequency of a cat’s purr (between 25 and 150 Hertz) falls within the range that supports tissue regeneration.
Bone and Muscle Healing
Vibrations at these frequencies have been shown to improve bone density and promote healing in muscles and tendons. This might explain why cats often purr when they are injured or in pain???it is a self-soothing and self-healing mechanism.
Benefits for Humans
The benefits extend to owners too. Studies suggest that cat owners have a 40% lower risk of heart attack. The presence of a purring cat lowers blood pressure and reduces stress levels, acting as a natural therapeutic agent.
