(Best Syndication News) - A study of rats found that bone and marrow abnormalities were present in rodents who lacked sleep on a long-term basis. The researchers found abnormal blood serum levels that measure bone metabolism in the rats lacking in sleep. The study was reported in the September 2012 issue of Experimental Biology and Medicine.

Researchers from the Medical College of Wisconsin investigated further by directly measuring bone parameters in rats that had been sleep deprived for much of their young adulthood.

(Best Syndication News ) - Making healthy lifestyle choices in old age can increase lifespan by up to six years for men and up to five more years for women, according to a Swedish study published in the online edition of BMJ. Healthy lifestyle choices include not smoking, eating right, staying physically active, and staying socially.

The researchers wanted to see if having healthy habits were just as important after a person turns 75. They wanted to see if there was an extension on a person's lifespan.

To investigate, the researchers studied 1,800 participants that were tracked from 1987 to 2005. Over the 18-year period, the participants were documented for their age, sex, occupation, education, lifestyle habits, what they did in their leisure time, and their socializing network.

(Best Syndication News) - A study found that people who are physically fit during the 30’s, 40’s, and 50’s have a better chance at a longer lifespan and at the same time they could improve their chance that they will remain in good health in their last years of life. Researchers from UT Southwestern Medical Center and The Cooper Institute published their findings in the online edition of the Archives of Internal Medicine.

Regular aerobic exercise has previously demonstrated a reduced death risk. In this study, the researchers wanted to find out if being physically fit in midlife would change the rate of chronic disease in the last years of life.

(Best Syndication News) - A study found that eating cocoa flavanols on a daily basis might help to improve mild cognitive impairment such as memory loss. The study results were published in the American Heart Association's journal Hypertension.

Flavonols are compounds that naturally occur in apples, tea, grapes, red wine, and cocoa. Other research has suggested that consumption of flavonols might reduce the risk of developing dementia.

One theory as to why flavonols may benefit the brain is that they could help improve blood flow. Another idea is that flavonols might work within the brain structure and thereby preserving function and neurons. The idea is that the flavonols might improve metabolism and may help with the molecular structure that is involved with memory.

(Best Syndication News) - A study found that middle-aged adults who kept active on a regular basis during their leisure-time had better protection for the heart than those who remained inactive. The research was published in the American Heart Association’s journal Circulation.

The researchers investigated over 4,200 study participants with an average age of 49 to determine if leisure-time physical activities provided benefits to keeping a heart healthy. The leisure-time activities included brisk walking, vigorous gardening, cycling, sports, housework, and home maintenance.
