You no doubt have seen advertisements asking people to join a clinical trial and thought they don't apply to you. But perhaps you should reconsider.

"People have a vested interest in the outcome of research trials, since these studies address many issues they want to avoid or better manage, such as cancer, diabetes, blood pressure, and dementia," says Dr. Howard Sesso, an epidemiologist with the division of preventive medicine at Harvard-affiliated Brigham and Women's Hospital.

Stopping exercise for 10 days can reduce brain blood flow by 20% to 30% in eight brain regions, including the hippocampus, which is responsible for learning and memory and is one of the first brain regions to shrink in Alzheimer’s disease.

These tiny devices can improve your communication, your relationships, and even your brain function, but only if you use them.

Age-related hearing loss affects about a quarter of people ages 65 to 74 and half of those ages 75 and older, according to the National Institute on Deafness and Other Communication Disorders. Over all, though, it tends to be more male-oriented.

“By middle age, many men also have hearing nerve damage from long exposure to noises like power tools, music, and guns,” says Dr. Steven Rauch, an otologist with Harvard-affiliated Massachusetts Eye and Ear. Some career choices—like construction, manufacturing, or military service—also contribute.

Participating in a medical study may benefit your health and perhaps that of millions of others.

If you've ever considered donating your body to science—or granting science a temporary loan—now's the time to do it. Researchers are always recruiting patients for studies of new treatments and preventive strategies for diseases ranging from Alzheimer's to zoster (shingles). In the simplest terms, these studies compare existing approaches to newer ones in similar groups of people and determine which is more effective.

"Clinical trials are the vehicle by which we transfer things that we think into things that we know or don't know," says Dr. Jeffrey Drazen, professor of medicine at Harvard Medical School and editor in chief of The New England Journal of Medicine.

You may be able to save time and money—and spare yourself frustration—by adopting a more minimal approach to preventing disease.

As the Shaker lyrics go, "'Tis the gift to be simple," and simplicity is a gift you might want to grant yourself in the new year. If so, you'll have some help from health experts. In the past few years, complicated advice for diet and exercise has given way to simpler, more sustainable guidelines, and the FDA has come down in favor of simple soap and water over antimicrobial cleaners to prevent infectious diseases.

If you've vowed to make positive changes in your lifestyle this year, you're likely to be more successful if you don't take on complex new regimens. "People can achieve remarkable changes in their lives one small step at a time," says Dr. Edward M. Phillips, assistant professor of physical medicine and rehabilitation at Harvard Medical School and medical editor of the Harvard Special Health Report Simple Changes, Big Rewards (www.health.harvard.edu/change).
