Lately you've felt like a flipping fish is stuck inside your chest. You feel fine otherwise, but there it is again — flip, flop. It's gone as fast as it appears. But you're starting to worry: is it a sign of a serious heart problem?

Chances are what you're feeling is a condition called heart palpitations, which are usually harmless blips in the heart rhythm, explains Dr. Peter Zimetbaum, a professor of cardiovascular medicine at Harvard Medical School. Only occasionally are these rhythm disturbances the sign of a more serious heart problem that should be checked out.

The emotional weight of grief affects the body in the form of stress, which can make existing conditions worse or cause new ones, and can also lead to depression. Maintaining health may seem difficult while grieving, but doing so can help rebuild mental strength.

No one is "perfect." Yet many people struggle to be a perfectionist , which can trigger a cascade of anxieties. Striving to be a perfectionist may be a strong suit or a stumbling block, depending on how it's channeled, as clinical psychologist Jeff Szymanski explains. Dr. Szymanski is an associate instructor of psychology at Harvard Medical School and executive director of the International OCD Foundation.

"The core of all perfectionism is the intention to do something well," says Dr. Szymanski. "If you can keep your eye on intention and desired outcome, adjusting your strategy when needed, you're fine.... But when you can't tolerate making a mistake, when your strategy is to make no mistakes, that's when perfectionism starts veering off in the wrong direction." In its most severe form, perfectionism can leave you unable to complete any task for fear of making a mistake.

Research we're watching

Stressful events — even positive ones, such as watching an exciting sporting match — can affect your heart. During World Cup soccer and the National Football League's Super Bowl, rates of heart attacks and heart rhythm problems (arrhythmias) increase, both among sports fans and within the local population. A study published online August 20 by the American Journal of Cardiology takes a closer look at this risk.

Researchers examined data from 133 people with implanted cardiac devices in St. Louis, Mo., during two 10-day periods. The first was in early September of 2011 (the control period). The second was six weeks later during the World Series, when the St. Louis Cardinals played a series of dramatic games against the Texas Rangers.

Psoriasis is a big star on TV drug ads, but this autoimmune skin disease is something most people try to keep well hidden.

"Psoriasis is among the most common skin conditions, affecting about 2% of the U.S. population, and while the condition doesn't affect everyone the same way, the approach to treatment and prevention is often similar," says Dr. Gideon Smith, an assistant professor of dermatology at Harvard-affiliated Massachusetts General Hospital.

Every day, carve out a little time to release your worries and relax your mind. It may counteract the heart-damaging effects of stress.

Stress is an inevitable part of life. People often fret over day-to-day hassles such as traffic jams and unpaid bills, not to mention the relentless news about natural disasters and political crises. Many are also coping with the added anguish of divorce, illness, or death within their families.

All of these so-called psychosocial stresses first take hold in your mind. But the effects spread throughout your brain and body. Sometimes, you can even feel it: your heart pounds, you breathe faster, and your muscles tense. However, chronic stress also has more insidious physical effects that can harm your heart (see "Stress and your cardiovascular system").
