full+moonThe next time you can’t go back to sleep, look out the window and up at the sky; a full moon may be working its mojo. HealthDay reports that researchers at the University of Basel studied the sleep pattern of 33 healthy people who spent three and a half days in a sleep lab, where they were unable to see clocks or outside light. Scientists tracked their hormones and brain activity, and recorded how long it took people to fall asleep, as well as their total sleep time. The researchers then took all the data collected on nights of normal sleep and compared it to the phases of the moon. Guess what? In the four days before and after a full moon, the sleepers got an average of about 20 minutes less sleep, and the amount of time they spent in deep sleep decreased by about a third.  They also made less melatonin, the hormone that makes people feel drowsy after dark.

    Walnuts Slow Prostate Cancer

    Yes, it appears to be true: walnuts slow the growth of prostate cancer, at least in mice. A UC Davis news release reports that researchers at the school had found, in a previous study, that walnuts reduced prostate tumor size in mice, but the researchers weren’t sure which parts of the nuts generated these benefits. This time around, the researchers used a mixture of fats with virtually the same fatty acid content as walnuts as their control diet. Mice were […]

    Ski Season Is Just Around The Corner. Are You Ready?

    It’s true that many midwesterners are less than thrilled with this week’s blast of winter weather, but skiers elsewhere are getting psyched. But wait, there’s something else: getting in shape. A quick review of the forest of websites offering get-into-ski-shape advice reveals general agreement on the benefits of two exercises: squats and lunges. The rest, my friends, is chatter. Livestrong.com describes squats as “the cornerstone” of your skiing workout,” and recommends that you compound the gain (and pain) by doing […]

    Why Scratching An Itch Makes It Worse

    No, it doesn’t make sense. Why would scratching an itch make it itch even more? It’s like eating food making you more hungry. Researchers at Washington University in St. Louis thought so too, so they did some scratching experiments–with mice, of course, not humans, to find out why. Why? It’s about itch signals and pain signals and brain chemicals jumping tracks.  A Wash U news story reports that the researchers found that scratching creates a mild amount of pain in the skin, which […]

    Another Bad Way To Treat Low-Grade Prostate Cancer

    It’s called androgen deprivation therapy, ADT for short, and it works like this: drugs (and there are several that can be used) are administered, often by injection, to suppress testosterone production, because lowering testosterone levels has been shown slow the growth of prostate cancer cells. But wait. Now, from researchers at Tulane University, comes a study showing that for men with low-grade, slow-growing disease, ADT can do more harm than good. There are two reasons for that: one, low-grade prostate […]

    No, you don’t need exotic machineries; you don’t even need a gym. Here’s what you need: a chair, a wall, and gravity, which is widely available at no cost. Wait, you also need seven minutes. That’s how long it takes, according to New York Times Health columnist Gretchen Reynolds, to stay is shape, but you have to be willing to really put out during those seven minutes. Writing in the Times, Reynolds gives us 12 exercises recommended by Chris Jordan, the […]

    How To Lose Weight: Stay Cold and Hungry

    There are some very pleasant ways to keep the weight off–playing tennis or swimming–and then there are two much less pleasant conditions that researchers at Yale believe could do the same thing, by turning white fat (bad) into brown fat (good.) Cold and hunger. Yes, staying cold and hungry could keep us thin. Maybe.  Yale News reports that researchers at the Yale School of Medicine have uncovered a molecular process in the brain known to control eating that transforms white fat into brown […]

    Computer Brain Games Are For Losers

    Brain games, the computer based mental challenges that promise to boost the brain power of older adults, are an excellent way to waste time, but they do almost nothing to make us smarter. That’s the opinion of 69 scholars, including many cognitive psychologists and neuroscientists from around the world. A Stanford University news release reports that the scholars, who have jointly issued a statement expressing their skepticism, say that while people who play computer brain games may improve their scores on […]

    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 […]
