Research we're watching

If you're able to quickly shrug off stressful events, that may be good for your health. A study in the March 19 issue of Psychological Science found that people who held on to stress—those who reported still having negative feelings about a stressful event the day after it happened — had more chronic health problems a decade later.

Researchers analyzed data from a nationwide survey that asked more than 1,100 adults about the number and type of stressful experiences they had each day for eight days. These included everything from arguments with others to problems at work, home, or school. Participants rated their emotional reactions to these stressors at the time and afterward.

Growing your real-life social network is important for health. Consider these ideas to get started.

When we're young, networking can be an important strategy to get ahead in business. Making new acquaintances and building relationships can lead to career opportunities. But later in life, networking takes on new significance: you may need it to stay connected socially. "Your social network shrinks. Your children leave home, you're no longer at work, or you've moved away. And that can lead to isolation and loneliness unless you maintain or rebuild your network," says Dr. Joel Salinas, a neurologist who specializes in behavioral neurology and neuropsychiatry at Harvard-affiliated Massachusetts General Hospital.

Isolation and loneliness

Many studies have linked isolation (being cut off from social contact) with a greater chance of having a heart attack or a stroke. A study published online March 27, 2018, by Heart suggested that isolation was independently associated with a 25% to 32% increased risk of death among people followed for seven years who had already had a heart attack or stroke.

This heart rhythm disorder is linked to thinking and memory problems. But anti-clotting drugs may lower the risk.

Bouts of atrial fibrillation, or afib — a rapid, chaotic heartbeat — make some people feel lightheaded and dizzy, while others don't notice any symptoms. But the most serious threat of this condition is the higher risk of stroke among people with afib compared with those without the disorder (see "Blood clot dangers, large and small"). Now, there's a growing recognition that people with afib also face an increased risk of thinking and memory problems — even if they do not experience a stroke.

Known as cognitive impairment, these problems include trouble remembering, learning new things, concentrating, or making routine decisions. The presumed underlying cause? Tiny blood clots that cause "silent" (that is, unrecognized) strokes and gradually injure parts of the brain involved with cognition.

Strengths are built-in capacities for certain thoughts, feelings, and behaviors. Everyone has these capacities to one degree or another. Your particular pattern of strengths is part of what makes you unique.

When you play from your strengths, you are likely to feel more energetic and perform better than when you are trying to use a capacity that comes less naturally. For example, one person trying to influence a local school board to ban soft drink sales might have the strength to speak up forcefully and clearly at a general meeting (despite the almost-universal fear of public speaking). Another person strong in team-building might feel uncomfortable speaking out in a meeting but could successfully build consensus among parents, nutritionists, and others to weigh the issue and come to a decision.

Benefits such as mental stimulation and social engagement are associated with staving off chronic disease.

Punching a time clock is still part of the regular routine for an increasing number of older adults. They're staying employed or going back to work, even though they're beyond the traditional retirement age of 65.

"For well over 100 years, men had been retiring at earlier and earlier ages. Something shifted in the 1990s, and they began working longer. The story for women is different. They weren't always in the labor force. But now we see employment rates rising for women at every age," says Nicole Maestas, an associate professor of health care policy at Harvard Medical School. She studies the economics of aging, health, and disability.

These strategies may offer greater protection.

While there's no cure for Alzheimer's disease, ongoing research has suggested there may be ways to lower your risk.

"Much of the existing science supports how certain behavioral changes made in middle age can protect people as they grow older," says Dr. Kirk Daffner, director for the Center for Brain/Mind Medicine at Harvard-affiliated Brigham and Women's Hospital. "However, there is evidence that adopting certain healthy lifestyle habits can benefit older adults too."

Sometimes the emotional part of cancer is the toughest test.

Any kind of cancer diagnosis is life-changing. There suddenly are many decisions to make about treatments, possible surgery, and recovery. It can be a lot to deal with. But one part of the cancer process that often gets pushed aside is the psychological aspect — how do you manage the many emotions that come with it?

"The natural response to hearing 'cancer' is to feel a surge of anxiety and negative thoughts like 'I'm going to die,'" says Dr. John Peteet, head of the psychosocial oncology fellowship at the Harvard-affiliated Dana-Farber Cancer Institute. "Yet many men are reluctant to admit this and keep their feelings inside, so it's tough to know when they need help with this part of a cancer diagnosis."
