Cat owners of the world all know the comfort of having a feline friend. Science takes this notion even deeper, with reason to believe that cat purrs could have medical benefits to both cat’s themselves, and us humans!
Though purring is generally considered an indication of a cat being comfortable and happy, felines often purr when they are injured or frightened. This contradictory notion has raised the theory that low energy mechanical stimulation can be used to aid a number of medical issues.
Low frequency biomechanical stimulation is a technique that utilises a specific set of frequencies to stimulate the soft tissues inside the body. Evidence claims that low energy simulation can help improve chronic venous insufficiency and promote joint healing from inflammation. In sports medicine, these frequencies are also thought to nurture strained muscle structures and increase the elasticity of tendons and capsules.
Cat purrs oscillate between exhalation and inhalation, at a frequency range of 20 to 150 Hz, which is a low lying frequency range. This has led researchers to consider how cat purring could have health benefits to pet owners.
It is known that cats have adapted to save energy through long periods of sleep and rest. So, it is a working theory that purring during sleep is a low energy mechanism responsible for stimulating the bones and the muscles in cats, without requiring excessive energy.
"there is also a link to stress reduction, heart attack prevention, and decreased symptoms of dyspnea (difficulty catching breath)"
On top of the muscular and osseous benefits of low range frequency stimulation, there is also a link to stress reduction, heart attack prevention, and decreased symptoms of dyspnea (difficulty catching breath).
Although studies on the subject are minimal, cat purr frequencies, as a bioceutical (natural medicine), have gotten the attention of scientists. So, while we wait for further investigation, get the most out of these soft melodies from your feline pets.
