Idling toward death: Sitting linked to dying early ABC News Share     Sitting around too much in one's spare time appears to increase the risk of dying, regardless of physical activity, researchers found. Among more than 120,000 adults, those who sat more than six hours a day in their leisure time were significantly more likely to die in a 14-year period than those who sat less than three hours, according to Alpa Patel of the American Cancer Society in Atlanta, and colleagues. The association was stronger in women than in men, the researchers reported online in the American Journal of Epidemiology. More
What, me worry? The Boston Globe Share
Everyone knows that spending too much time in the sun is bad. It'll give you leathery skin and increase your risk of skin cancer. But it feels great to see that glow in the bathroom mirror — it just looks healthier, doesn't it? And catching only a few minutes of sunshine a day boosts vitamin D levels. The question of how much time to spend in the sun requires a judgment on the risk of bad things happening — skin damage, cancer — against the possible benefits — that lovely glow. But we are lousy at calculating such risks. More Cholesterol study: Low HDL may not be so bad WebMD Share
Patients on statin drugs who reduce their LDL "bad" cholesterol to very low levels may not need to be so concerned about boosting their HDL "good" cholesterol levels for protection against cardiovascular disease, according to a new study. "Once we get the levels of LDL down to very low levels, it becomes unclear whether HDL is an important determinant of [cardiovascular] risk," says researcher Paul Ridker, MD, director of the Center for Cardiovascular Disease Prevention at Brigham & Women's Hospital, and professor of medicine at Harvard Medical School, Boston. More With this rinse, performance improves The New York Times Share
Exercise scientists say they have stumbled on an amazing discovery. Athletes can improve their performance in intense bouts of exercise, lasting an hour or so, if they merely rinse their mouths with a carbohydrate solution. They don't even have to swallow it. It has to be real carbohydrates, though; the scientists used a solution of water and a flavorless starch derivative called maltodextrin. Artificial sweeteners have no effect. More Diet and behavior changes may slow Alzheimer's U.S. News and World Report Share
A combination of diet and lifestyle changes decreases Alzheimer's-like symptoms in dogs more than either treatment does on its own, a new study shows. The findings show the importance of taking multiple approaches to arrest the disease in humans, the authors say. Their results also provide evidence supporting recent research that suggests plaque deposits in the brain are not the cause of Alzheimer's. More
Lifestyle interventions needed to stay heart-healthy HealthDay via Bloomberg Businessweek Share
There's no lack of scientific evidence proving that staying in shape and eating right are critical to a long and healthy life, but the fact that over 8 million Americans have histories of heart attack, stroke or heart failure suggests that too few are taking the message seriously. That's the theme of a new scientific statement from the American Heart Association (AHA), which reviewed 74 previously published studies and developed specific behavioral-health strategies to help people stay heart-healthy. More Knee ligament tears often need no surgery: study Reuters Share
Most people who have a common knee ligament injury fare just as well with intense physical therapy as they do with surgery, according to a study comparing the two techniques released recently. Researchers said that focusing on rehabilitation first could prevent more than half of operations done to repair a tear in the anterior cruciate ligament (ACL), which lies beneath the kneecap and attaches the thigh bone to the shin bone. More Deceptive marketing of dietary supplements Forbes Share
Without any fanfare, Congress held a hearing recently on how supplements are marketed to the elderly. The Government Accountability Office (GAO) conducted a study of 40 different herbal supplements, looking at what the supplements actually contained as well as how they were being sold, both in stores and online. Not surprisingly, the GAO found that companies have been making deceptive, inaccurate claims about many of the most popular supplements sold in the U.S. More A robot that helps you diet The Wall Street Journal Share
Autom is a weight-loss coach. She knows how much you've been exercising, and she knows your diet. With a touch of your finger, she knows if you're in a good mood. Autom is also a robot, and her inventor hopes she can help people lead healthier lives. Cory Kidd, co-founder and chief executive of Intuitive Automata Inc., built the first incarnation of Autom by hand while studying at the Massachusetts Institute of Technology's Media Lab and seeing patients at Boston Medical Center's clinic. Mr. Kidd, 32 years old, saw an opportunity to create "something that could be a very large benefit," he said. More |
