More trees, fewer heart risks?

Research we're watching

Living in a leafy, green neighborhood may lead to lower levels of some telltale markers for heart disease and stroke, new research suggests.

During the five-year study, researchers collected blood and urine samples from 408 people recruited from a cardiology clinic in Louisville, Ky. The researchers also estimated green space exposure using satellite imagery that showed the vegetation density in each of the participants' neighborhoods.

Skipping a beat — the surprise of heart palpitations

Interesting heart palpitations causes and treatment for a case of the heart flutters

Does your heart unexpectedly start to race or pound, or feel like it keeps skipping beats? These sensations are called heart palpitations. For most people, heart palpitations are a once-in-a-blue-moon occurrence. Others have dozens of these heart flutters a day, sometimes so strong that they feel like a heart attack.

Most palpitations are caused by a harmless hiccup in the heart's rhythm. A few reflect a problem in the heart or elsewhere in the body.

Grief can hurt — in more ways than one

Stress and depression may lead to new health issues or intensify the symptoms of existing conditions.

We tend to think of grieving as an emotional experience, and it is — fraught with intense sadness, profound loss, and psychological pain. But grief has a physical side that sets us up for a number of health risks. "Most of these side effects are the result of emotional distress responses," explains Dr. Maureen Malin, a geriatric psychiatrist with Harvard-affiliated McLean Hospital. Whether you're grieving the loss of a loved one, a job, a home, or a beloved pet, it's important to understand how the process puts your health in jeopardy.

Stress and grief

Grieving takes a toll on the body in the form of stress. "That affects the whole body and all organ systems, and especially the immune system," Dr. Malin says. Evidence suggests that immune cell function falls and inflammatory responses rise in people who are grieving. That may be why people often get sick more often and use more health care resources during this period.

Heart palpitations: Mostly harmless

Occasionally these heart rhythm disruptions signal a more serious condition.

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.

Grieving? Don’t overlook potential side effects

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.

Trying to be perfect can cause anxiety

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.
