A new study has good news — if you’re the optimistic type, at least. Researchers found that people with positive outlooks on life showed a strong correlation with good cardiovascular health.

Rosalba Hernandez, lead author of the study and professor at the University of Illinois at Urbana-Champaign, said in a statement that the research found that people with the highest levels of optimism had “twice the odds of being in ideal cardiovascular health compared to their more pessimistic counterparts.”

Even when the study adjusted for socio-demographic characteristics and poor mental health, the results remained consistent, she said, according to International Business Times.

Heart disease is the most deadly illness facing the United States, killing about 2,200 Americans every day. The American Heart Association states that about one in 18 Americans are killed by a stroke.

Mounting research reveals that you cannot separate your health from your emotions, and numerous studies support the idea that having an upbeat and positive perspective can translate into living a longer healthier life.

For example, in one older study, pessimism was linked to a 19 percent higher risk of dying over a 30-year period.

More recently, studies have confirmed the link between optimism and heart health specifically. One 2011 study found that those who reported higher levels of satisfaction in areas like career, sex life, and family had a reduced risk for heart disease.

Optimism Promotes Heart Health

After examining the associations between optimism and heart health in more than 5,100 adults of various ethnic groups for 11 years, researchers at the University of Illinois report that people who display a more optimistic can-do attitude in life experience significantly better cardiovascular health over the long term.

People who were the most optimistic were up to 76 percent more likely to have a total health score in the ideal range. The health scores were based on seven metrics used by the American Heart Association (AHA) to define heart health.

This includes blood pressure, body mass index, fasting plasma glucose, serum cholesterol levels, diet, exercise, and smoking. According to study author Rosalba Hernandez:

“Individuals with the highest levels of optimism have twice the odds of being in ideal cardiovascular health compared to their more pessimistic counterparts. This association remains significant, even after adjusting for socio-demographic characteristics and poor mental health…

At the population level, even this moderate difference in cardiovascular health translates into a significant reduction in death rates.

This evidence, which is hypothesized to occur through a biobehavioral mechanism, suggests that prevention strategies that target modification of psychological well-being – e.g., optimism – may be a potential avenue for AHA to reach its goal of improving Americans’ cardiovascular health by 20 percent before 2020.”

Can You Die from a Broken Heart?

If optimism and happiness can boost your heart health, what about the more extreme of negative emotions: grief? You sometimes hear stories of elderly partners dying within weeks, days, or even hours of each other; or people who suffer deadly cardiac events following some other severe emotional blow.

But can you really die from a “broken heart?” Researchers say yes. Losing a significant person in your life raises your risk of having a heart attack the next day by 21 times, and in the following week by six times.

The abrupt increase in risk of cardiovascular events like heart attack following a heartbreak is thought to be related to the flood of stress hormones your body is exposed to.

The risk of a heart attack begins to decline after about a month, likely because the levels of stress hormones start to level back out. The loss of a loved one also increases your risk of stress cardiomyopathy, which is sometimes referred to as “broken heart syndrome.”

The symptoms of stress cardiomyopathy are very similar to those of a typical heart attack, including chest pain, shortness of breath, low blood pressure, and even congestive heart failure. There are some key differences, however.

My Personal Challenges with a Broken Heart

Fortunately I have only had to go through acute grieving once, about 20 years ago when the relationship with the woman I love ended. The grief and sadness progressed into a full blown depression; I lost 30 pounds and got down to 150 pounds, which is really thin for someone nearly 6’2”.

This was the most painful and stressful period of my life and it took me many months to recover. One of the strategies I used was to seek to make some good of that terrible situation. I committed the extra time and energy to creating this newsletter and that seemed to help not only me but many others.

Even though I was healthy, it was obvious to me how these changes could seriously harm or even kill you.

Now, we know that stress and the subsequent release of stress hormones can “stun” or “shock” the heart, leading to sudden weakness of the heart muscle. This condition can be life-threatening and requires immediate medical attention, but it’s usually a temporary condition that leaves no permanent damage.

The Science of Happiness

While conventional medicine is still reluctant to admit that your emotional state has a major impact on your overall health and longevity, a 2013 article in Scientific American discusses a number of interesting advancements in the emerging field of psychoneuroimmunology (PNI).

Researchers are finding that your brain and immune system are wired together, and portions of your nervous system directly connect with immune-related organs. Your immune cells also have receptors for neurotransmitters, which suggest they can be more or less directly influenced by them.

Researchers have also investigated the genetic effects of various mental states. For example, in one study, chronic loneliness was associated with the up- and down-regulation of specific genes. Genes involved in the regulation of inflammatory response were upregulated, while genes involved with antiviral control were downregulated. The end result was decreased immune function. In socially active people, the reverse was true. This was one of the first studies to link a psychological risk factor with actual changes in gene expression.

Two Types of Happiness Produce Different Genetic Responses

In another happiness study, participants answered questions about the frequency of certain emotional states, covering two categories or types of happiness known to psychologists as:

Hedonic well-being – characterized by happiness gleaned from pleasurable experiences

Eudaimonic well-being – happiness that arises from activities that bring you a greater sense of purpose, life meaning, or self-actualization

Interestingly, while both are positive emotional states associated with happiness, the gene expressions they produced were not identical. Those whose sense of happiness was rooted in the eudaimonic camp were found to have favorable gene-expression profiles, while hedonic well-being produced gene profiles similar to those seen in people experiencing stress due to adversity.

According to the author, Steve Cole of the Cousins Center, the happiness you glean from hollow consumption activities or pleasurable experiences is very dependent on your circumstances, which can change quickly and drastically. So when you run into adversity, you may become quite stressed—for example, if you can’t afford a certain activity anymore, you feel increasingly “unhappy.” Eudaimonia on the other hand, in which happiness is centered around the feeling of life having a greater purpose, helps buffer against perceived threats and stress, and therefore tends to have a beneficial impact on your health.

Secrets of Happy People

Being able to manifest positive emotions and happiness is perhaps one of the greatest gifts you have been given as a human being. But to some extent, being happy is a choice you need to make, much like choosing to exercise or eat right. Happiness comes from within—it’s not meted out by circumstance alone. This is why, if you truly want to be happy, you need to work on yourself first. And the health benefits mentioned above, like a significantly reduced risk of heart attack and other cardiac events, should provide ample motivation for doing so.

Interestingly, self-acceptance appears to be one of the most important factors that can produce a more consistent sense of happiness. In a survey of 5,000 people by the charity Action for Happiness, people were asked to rate themselves between 1 and 10 on 10 habits that are scientifically linked to happiness. While all 10 habits were strongly linked to overall life satisfaction, acceptance was the strongest predictor. In all, the survey resulted in the following 10 Keys to Happier Living, which together spell out the acronym GREAT DREAM:

Giving: do things for others

Relating: connect with people

Exercising: take care of your body

Appreciating: notice the world around you

Trying out: keep learning new things

Direction: have goals to look forward to

Resilience: find ways to bounce back

Emotion: take a positive approach

Acceptance: be comfortable with who you are

Meaning: be part of something bigger

Another way to think about happiness is to define it as “whatever gets you excited.” Once you’ve identified that activity, whatever it is, you can start focusing your mind around that so you can integrate more of it into your day to day life.

Other studies have suggested that there is a link between mental health and physical health. For example, an AHA report last summer suggested that high levels of stress and hostility were associated with a greater risk of stroke. A 2012 Harvard tudy also noted that positive emotions and optimism appeared to reduced the risk of heart problems.

However, this latest study appears to be the first that specifically looks at how optimism factors into heart health.
