Loneliness Ages You, Fast

May 5, 2012 7:47 am 0 comments

Turns out that one isn’t just the loneliest number, it’s the number that makes us old, fast. Researchers at Cornell University have found that the social pain of loneliness produces changes in the body that mimic the aging process and increase the risk of heart disease. A Cornell news release reports that the researchers, who measured cardiovascular reactivity and recovery in 91 young adults (18-30 years old) and 91 older adults (65-80 years old), found that the cardiovascular response of the lonely young adults to the social stressor task looked more like that of the nonlonely older adults. They also found that loneliness increased resting blood pressure, cardiovascular stress reactivity and cardiovascular recovery times in the older people. In fact, the recovery time of the lonely older adults was so delayed they didn’t return to baseline levels during the two-hour-long follow-up period. Read more from Cornell.

    Exercise Pain Predicts Broader Pain Threshold

    How much you hurt after exercise is a good predictor of how much you hurt in life, according to research conducted at the Rutgers School of Dental Medicine, where they know a thing or two about pain. Researchers have known for years that exercise generally helps us tolerate pain. They even have a name for the phenomenon; it’s called “exercise-induced hypoanalgesia” or (EIH), but you knew that. Researchers have also known that some people respond better to the pain-diminishing influence of […]

    Worried About Ebola Yet?

    Are you worried about Ebola yet? At least one out of four American are, according to a new Harris Poll/HealthDay survey. And the most disturbing thing about the poll is that it was taken more than a week ago, before a nurse in Dallas who had treated an Ebola patient became sick, compelling the CDC to rethink the preparedness of U.S. medical workers to deal with the crisis. HealthDay reports that the online poll of more than 2,000 adults, taken between Oct. […]

    Repeat Knee Injuries: What Are The Odds?

    Ever wonder what the odds are that you’ll re-injure a knee after an ACL repair? Now we know, and the answer is: it depends how old you are.  If you’re in high school, and if you are reading this you are probably not in high school, you’ve got a 17 percent chance of re-injury. That sounds scary until you read the full report from researchers at the University of North Carolina, which claims a 20 percent chance of injury on […]

    Lifting Weights Improves Your Memory

    Can’t remember how many reps you should do of squat thrusts? Do a few more reps and it might come back to you. Slowly. Researchers at Georgia Tech are persuaded that an intense workout of as little as 20 minutes can enhance episodic memory, also known as long-term memory for previous events, by about 10 percent. A Georgia Tech news release admits that the school isn’t the first to find that exercise can improve memory, but their study, which was […]

    Knee Pain? Forget About Acupuncture

    Got a knee that won’t stop giving you pain? Don’t waste your time with acupuncture. According to researchers at the University of Melbourne in Australia, the therapy does little for knee pain in the short term and it does nothing in the long term. Science Daily reports that the researchers treated 300 adults with chronic knee pain either with needle acupuncture, laser acupuncture (hitting acupuncture spots with a low-intensity laser beam), sham laser acupuncture, or no treatment at all (the […]

    Karate Masters Have Faster Brains

    Researchers have known for a while that the power of a karate blow is not all about strength. Rather, it’s about fine coordination between wrists and shoulders. Now researchers at University College in London have learned where that better coordination comes from: a better brain. A University College news release reports that researchers looked for differences in brain structure between 12 karate practitioners with a black belt rank and an average of 13.8 years’ karate experience, and 12 control subjects […]

    Exercise Is Bad For Your Teeth, Maybe

    OK, this is surprising. As Gretchen Reynolds points out in the New York Times, exercise may be good for every part of your body but one: your teeth. Reynolds reports that the good health/bad teeth dichotomy came to the attention of many last year when a study was published in The British Journal of Sports Medicine, in which dentists who examined 278 athletes at the 2012 Summer Olympics in London reported that a majority displayed “poor oral health,” including high levels […]

    FDA Wants A Closer Look At Testosterone Risks

    Testosterone replacement therapy may make older men feel younger, but according to some studies, it can also push them closer to the grave. The Wall Street Journal reports on a 2013 study, published in the Journal of the American Medical Association, that found a 30 percent increased risk of death, heart attack and stroke among men taking testosterone, compared with other men. That study and others like it, plus a 65 percent increase in sales of such products between 2009 […]
