healthbriefs Dream on… and Learn Better M


odern science has established that sleep can be an important tool for enhancing memory and learning skills. A new study at Beth Israel Deacon- ess Medical Center sheds light on the role that dreams play in this process. “After nearly 100 years of debate about the function of dreams, this study tells us that dreams are the brain’s way of processing, integrating and really un-


derstanding new information,” says senior author Robert Stickgold, Ph.D. “Dreams are a clear indication that the sleeping brain is working on memories at multiple levels, including ways that will directly improve performance.” Indeed, according to the researchers, these new findings suggest that dreams may be the sleeping brain’s way of telling us that it is hard at work on the process of memory consolidation— integrating our recent experiences to help us with performance-related tasks in the short run, as well as over the long term. In other words, dreams help us translate this material into information that has broad ap- plication in our lives.


Happiness Keeps Growing I


s there any good news about growing old? Research- ers reported at a recent American Psychological Association convention in Toronto that an increase of happiness and emotional well-being occurs as people mature. Their study of contributing factors showed that older adults exert greater emotional self-control, have learned to avoid or limit stressful situations and are less likely than younger adults to let negative com- ments or criticism bother them.

groundbreaking Swedish study has demonstrated that heart cells are able to regenerate themselves, overturning the conventional wisdom that the body cannot replace damaged heart cells. Examining the heart tissue of 50 people over four years, the researchers found that on average, new heart cells appeared to replace old ones at a rate of about 1 percent a year in youth and 0.5 percent a year by age 75. Thus, our heart comprises a mosaic of older and newer cells. Scientists hope to learn how to stimulate this organ’s ability to naturally regenerate.

Our Renewable Heart A


DIET MAY AFFECT OUR INTERNAL


CLOCK Our body’s internal clock, the circadian rhythm, helps it


adapt to the cycle of day and night and


regulates functions such as sleep and metabolism. Work- ing with lab animals, scien- tists at Hebrew University of Jerusalem have discov- ered that a high-fat diet can cause disturbances in this daily rhythm by affecting an animal’s clock-related genes. Significant health conse- quences include irregular sleep/wake cycles and meta- bolic disorders.


Stress-Busting Walnuts


A


diet rich in walnuts and walnut oil may prepare the body to deal better with stress, according to a team of Penn State researchers. They spe- cifically considered how these foods, which contain polyunsaturated fats, influence our blood pressure. Their studies showed that walnuts and walnut oil have the ability to lower blood pres- sure, both when we are at rest and in response to stress.
