Important health news...
... that you probably already knew. Purring cats are good for you!
(Elizabeth von Muggenthaler) recorded and then measured the purr of forty-four felids (members of the cat family) including cheetahs, ocelots, pumas, domestic cats, and servals. Cats, from your house pet to lions and tigers in the wild, generally purr in the range of 20 to 140 Hertz (Hz). Some are as high as 150 Hz but the average housecat comes in at about 25 and 50 Hz.
Research has already shown that exposure to frequencies at that same 20 and 50 Hz level induces increased bone density. In one study, for example, chickens were placed daily on a vibrating plate for 20 minutes, which resulted in stronger bone growth (National Geographic January, 2001 p. 11). Further, in 1994, Dr. Chen and his associates, working with rabbits, determined that frequencies of 25 and 50 Hz promoted bone strength by 20%, stimulating both the mechanism and speed of fracture healing (Chen et al, 'The Effects of Frequency of Mechanical Vibration on Experimental Fracture Healing'. Chinese Journal of Surgery, 32 (4), 217-219, 1994)
But it's the cat's "healing by association" that most people find interesting: that ability of a cat to sympathetically help cure illnesses in people simply by being around them. Studies have also shown that owners, especially senior citizens, who have cats have lower blood pressure and can live longer than humans who don't own pets. Many individuals swear they can ease or completely eliminate their migraine headaches simply by lying down with a purring cat next to their head.
Can't hit that minimum recommended daily dose of bone-enriching calcium? Maybe grabbing the nearest cat and holding it close may just prove to be the answer to brittle-bones. Having surgery? Perhaps after coming home, keeping a cat nearby will reduce your recovery time. So, go get a cat. Keep it happy and purring. You're both likely to be healthier and you'll have a great friend who truly understands how you're feeling.
