Anger or emotional upset may double the risk of having a heart attack. Heavy physical exertion appears to have the same effect. And people who do intense exercise while they’re upset or mad may face three times the risk of heart attack. 

A persistent cough that remains after an infection has been treated can last for a month or two. There are several treatments that may offer relief, such as antihistamines or a bronchodilator inhaler. 

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.

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).

Exploring why you're bored can stimulate creativity and lead to a better understanding of yourself.

Most of us have had times when we couldn't find anything satisfying to do or couldn't keep our attention focused on a lecture or book. If we were asked to describe how we felt at the time, we'd probably have answered "bored."

Boredom doesn't necessarily arise from having nothing interesting to do. For example, you can probably remember sitting quietly watching the sun slowly set and being completely enthralled. Compare that to another moment in which you've also sat quietly—but in slow moving traffic—and felt terribly bored. "What makes the difference is whether during a low-stimulation moment, there are unpleasant feelings in the background. Many of us habitually distract ourselves from unpleasant feelings through entertainment or activity—like checking our smartphones, or watching TV," says Dr. Ronald Siegel, a psychologist at Harvard Medical School and the medical editor of the Harvard Special Health Report Positive Psychology. "Sometimes when there is little to engage us, those unpleasant feelings bubble into our consciousness and we feel something unpleasant, which we identify as boredom. Other times we're content to just be present—like when enjoying a sunset."

Weight training improved mental performance in a study of 100 men and women ages 55 through 86 who had mild cognitive impairment.

Some research suggests that disclosing deep emotions through writing can boost immune function as well as mood and well-being. Conversely, the stress of holding in strong feelings can ratchet up blood pressure and heart rate, and increase muscle tension.

Deeply troubling situations, such as suicide or a violent death, are best explored with the help of an experienced therapist. You might want to seek professional support to help you start to deal with your grief before trying journal writing. If you'd like to try keeping a journal to help you process feelings of grief, keep these things in mind:

The flu season is upon us. Like that other season—winter—it can be unpredictable. But the Centers for Disease Control and Prevention (CDC) is doing its best to see that we're informed and as prepared as possible for whatever is in store. For updates throughout the flu season, check the CDC website, www.cdc.gov/flu.
