       Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.        Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort  than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress       levels and blood pressure in people – half of them pet owners – while they performed 5 minutes of       mental arithmetic (算术) or held a hand in ice water. Subjects (受试者) completed the tasks alone, with  a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal   friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With   pets in the room, people also made fewer math mistakes than when doing in front of other companions.   It seems people feel more relaxed around pets, says Allen, who thinks it may be because pets don't  judge.       A study reported last fall suggests that having a pet dog not only raises your spirits but may also  have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year  studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56  people without pets were put on a diet program. On average, people lost about 11 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more

exercise---mostly with their dogs---and found it worth doing.
