The jury is still out. Aspirin has long been known as an effective painkiller, but it's become as important for preventing stroke and heart attack as it is for preventing pain. Low-dose aspirin therapy helps prevent heart attack and stroke by keeping blood platelets from clumping together and forming dangerous clots. http://www.johnshopkinshealthalerts.com/reports/healthy_living/1530-1.html?CMP=OTC-RSS While a direct link between periodontal disease and heart disease has yet to be firmly established, doctors believe there is an important connection between oral and cardiovascular health.You may have cultivated an excellent working relationship with a caring and competent physician. You may be eating a heart-healthy diet and exercising regularly. But have you seen your dentist lately? This is an important question, because the state of your teeth and gums may impact your cardiovascular… http://www.johnshopkinshealthalerts.com/reports/healthy_living/683-1.html?CMP=OTC-RSS David Neubauer, M.D., Associate Director of the Johns Hopkins Sleep Disorders Center, talks about insomnia.A good night's rest can become a rare commodity as you age. This is because sleep patterns change as you get older: You spend more time in the lighter stages of sleep and less time in the deep, restorative stages. If you have trouble falling asleep or staying asleep more than three nights a week, or if lack of sleep leaves you exhausted, you probably have insomnia. David Neubauer, M.D., Associate Director of the Johns Hopkins Sleep Disorders Center and the author of Understanding Sleeplessness (Johns Hopkins University Press), explains his approach to insomnia and evaluates the new sleeping pills. http://www.johnshopkinshealthalerts.com/reports/healthy_living/552-1.html?CMP=OTC-RSS Johns Hopkins professor Adrian Dobs, M.D. talks about testosterone replacement therapy.After age 40, a man's testosterone level declines by about 1% each year. Most men don't experience symptoms. But if the testosterone level drops below 300 nanograms per deciliter (ng/dL), as measured by a blood test, this indicates a condition called hypogonadism that can only be treated with testosterone therapy. http://www.johnshopkinshealthalerts.com/reports/healthy_living/547-1.html?CMP=OTC-RSS Perhaps you've caught sight of them in a park on a sunny day -- people moving in synchrony as they perform a series of graceful, flowing movements. Most likely, they're practicing tai chi, an ancient Chinese form of exercise that can help people of all ages improve their flexibility, balance, and muscle strength.Now recent studies indicate that tai chi may help with a range of medical problems, including Parkinson's disease, high blood pressure, and rehabilitation after knee replacement surgery. http://www.johnshopkinshealthalerts.com/reports/healthy_living/376-1.html?CMP=OTC-RSS It is a well-established fact that better cardiovascular health gained by regular exercise reduces your risk of type 2 diabetes, heart attack, stroke, high blood pressure, and high cholesterol levels. Now, new research suggests that regular cardiovascular exercise might benefit your brain as well. Two separate studies published in the Journal of the American Medical Association report that walking regularly may help preserve mental sharpness. http://www.johnshopkinshealthalerts.com/reports/healthy_living/257-1.html?CMP=OTC-RSS In 2003, publication of the complete sequence of the human genome capped a decade of explosion in genetic knowledge. Later that year, researchers announced that much of this information had been placed on a single, dime-sized glass slide called a DNA microarray or gene chip. This tool allows researchers to rapidly examine humankind's estimated 35,000 genes so they can pinpoint those linked to disease, an achievement that promises to transform the practice of medicine in the near future. http://www.johnshopkinshealthalerts.com/reports/healthy_living/133-1.html?CMP=OTC-RSS If you're past midlife and have not yet quit smoking, chances are you'd like to quit smoking. Statistics show that most older smokers have tried—and failed—to quit smoking at least once. The addictive nature of nicotine, one of the major chemicals in tobacco, accounts for many of these failures."Tobacco delivers explosively high doses of nicotine to the brain," says Johns Hopkins Professor of Psychiatry Jack Henningfield, Ph.D., "causing neurologic changes that are http://www.johnshopkinshealthalerts.com/reports/healthy_living/62-1.html?CMP=OTC-RSS
