BEIJING, May 23 (Xinhuanet) -- A new study suggests that crossing your arms could reduce the intensity of pain, according to media reports.The study was conducted by researchers from University College London (UCL), who reported their finding in the journel Pain.They said that crossing the arms could confuse the brain and conflicting information between the brain's two maps - one for the person's body and the other for external space - leading to a lower sensation of pain.A laser was used to generate a four millisecond pin prick on the hands of eight volunteers, who experienced this twice with their arms at their sides and arms crossed.Then the participants were asked to rate the intensity of pain in two situations and an EEG (electroencephalography) was used to measure their electrical brain responses.The results showed that both the perception of pain and EEG activity was reduced when the arms were crossed."Perhaps when we get hurt, we should not only 'rub it better' but also cross our arms," said Giandomenico Iannetti of UCL's department of physiology, pharmacology and neuroscience.

LOS ANGELES, April 11 (Xinhua) -- Drinking 100-percent fruit juice may offer disease-fighting benefits, a new study suggests.Fruit juice is linked with reduced risk of cancer, improved markers of heart health and cognitive decline, and increased antioxidant activity, according to the study published on Monday by the American Association for the Advancement of Science (AAAS).These protective health benefits are similar to those of whole fruits, said the study, conducted by researchers at the University of California, Davis.The researchers came to the conclusion after summarizing recent research data on the potential benefits of fruit juice. The review included a range of study types, from in vitro to clinical trials (60 papers total), all published in 2005 or later.Among the fruit juices included in the review, consumption of apple, citrus, cranberry, grape, and pomegranate juices all showed beneficial effects. Markers of improved health ranged from reductions in urinary tract infections (cranberry) to improvements in age-related cognitive decline (grape and apple) to reduced risk of prostate (pomegranate) and respiratory and digestive (orange, grapefruit) cancers. Additionally, intake of all juices was linked to heightened antioxidant activity."While it is universally accepted that fruit and vegetable intake is protective, there is not a clear consensus about the benefits of consuming the juices that are extracted from them," said study lead author Dianne Hyson, PhD. "An analysis of the scientific evidence suggests that 100 percent fruit juices retain important bioactive components that may promote good health and aid in disease prevention."

LOS ANGELES, May 9 (Xinhua) -- Drinking alcohol may raise the likelihood among teenagers to spend more time on computers, a new study suggests.The study, conducted by researchers at Weill Cornell Medical College, was based on a survey of 264 teenagers, aged 13 to 17.Results showed that compared with teens who did not report drinking, those who drank alcohol in the last month used a computer more hours per week for non-school-related activities, including the use of social networking sites.Drinking was also linked to more frequent social networking and listening to and downloading music, according to the study published Monday in the on-line edition of the journal Addictive Behaviors.However, there was no demonstrated link between alcohol use and computer use for school work, neither there was strong link between video games and drinking or on-line shopping and drinking."While the specific factors linking teenage drinking and computer use are not yet established, it seems likely that adolescents are experimenting with drinking and activities on the Internet," said Dr. Epstein, assistant professor of public health at the college."In turn, exposure to on-line material such as alcohol advertising or alcohol-using peers on social networking sites could reinforce teens' drinking."Children are being exposed to computers and the Internet at younger ages. For this reason it's important that parents are actively involved in monitoring their children's computer usage, as well as alcohol use."Teenagers typically first experiment with alcohol at age 12 or 13, according to the study.Family risk factors include lax parental supervision and poor communication, family conflicts, inconsistent or harsh discipline and a family history of alcohol or drug abuse."According to a national study conducted by the Pew Internet and American Life Project, more than half of parents of teenagers had filters installed on the computers their child uses to block content parents find objectionable, yet many parents do not use any form of parental monitoring, particularly for older teens," Epstein said.

BEIJING, March 22 (Xinhua) -- China's State Food and Drug Administration (SFDA) has ordered a "serious investigation" into two kinds of bath products that reportedly gave children skin diseases.The order came after recent reports accused the body wash and lotion used by bathhouse chain Tian Po Po Xi Jiu Tang, or, literally, "Grandma Tian's Bathhouse," in southwest China's Sichuan Province of having "caused severe body damages," according to a SFDA statement released Tuesday.The bathhouse chain, with a history of some 70 years, was first established in Sichuan's capital Chengdu and was listed as a part of the city's Intangible Cultural Heritage in 2009.The licensed bathhouse claimed to use bath products developed by its own Chinese herbal medicine recipes that protected children from various skin ailments and other diseases, such as eczema, colds, and constipation.However, an unknown number of children suffered pustular psoriasis, a chronic skin irritation characterize by raised bumps, after washing at the bathhouse chain and using the two products, according to reports.Sichuan's provincial food and drug administration bureau previously deemed the two products to be "fake drugs" based on an initial investigation by the local police and food and drug authorities, the statement said.The SFDA urged local food and drug supervision departments across the country to monitor and check the two products sold by the bathhouse chain within their regions, and vowed to punish any violations of laws and regulations.

SYDNEY, March 30 (Xinhua) -- Work is good for health while long term work absence, work disability and unemployment can make us miserable, according to a consensus statement from the Australian and New Zealand doctors on Wednesday.The Australian and New Zealand Consensus Statement on the Health Benefits of Work was launched by the Royal Australasian College of Physicians (RACP) and the Australasian Faculty of Occupational and Environmental Medicine (AFOEM) in Wellington.In the statement, doctors say that work is generally good for health and long term break form work along with unemployment and being unable to work due to disability generally have a negative impact on wellbeing.Work is also an effective means of reducing social exclusion, particularly for indigenous people and other disadvantaged groups, the statement says."Work practices, workplace culture, work-life balance, injury management programs and relationships within workplaces are key determinants, not only of whether people feel valued and supported in their work roles, but also of individual health, wellbeing and productivity," it said."Good outcomes are more likely when individuals understand the health benefits of work, and are empowered to take responsibility for their own situation." the statement said.
