Is the Glass Half Full? Saying Yes Might Make You Healthier

Posted: 09/ 7/2011 2:40 am

I have heard people rant and rave and bellow, That we're done and we might as well be dead, But I'm only a cock-eyed optimist, And I can't get it into my head -- "South Pacific" (Musical), 1949

We all know a certain type of person -- we can see them coming down the hall from 100 yards away. They have an electric cord coming out of their torso with the plug tightly coiled in their right hand. They hope to plug into you and suck out all the positive energy they can. When I see them heading toward me, I usually duck into a patient room or laundry closet. Unfortunately, they may not realize their pessimistic and cynical attitudes are not only bad for their health but may eventually kill them.

The Basis of Optimism

As we struggle through a bad economy, multiple wars and uncivil political discussions it may not seem like it, but optimism still holds sway over pessimism. Optimism is the inclination toward hope, and it determines how we come to terms with our present, future and past events. An optimist believes that positive events are more likely to occur than negative events, and that those positive events are more likely to happen to him and the negative ones to others. He knows that there are all kinds of bad diseases, but he believes that they are more likely to happen to other people.

Tali Sharot, in her book "The Optimism Bias," states that optimism is highly resilient and may be hard wired from birth. She believes people are more optimistic than realistic. Think about that. Despite the often-quoted statistic that half of all marriages end in divorce, most people don't stand at the marriage altar and suppose that those statistics apply to them. The same is true for the chances of losing your job, getting cancer or predicting how long you will live. Sharot calls the belief that the future will be better than the past, the "optimism bias."

Optimism and Health

Stroke prevention typically focuses on controlling our blood pressure, cholesterol, weight and diabetes, but our attitude seems to also make a difference. A recent study published in Stroke looked at 6,044 people who were part of the Health and Retirement study. During a 2-year period, 88 of these people had a stroke. All of the participants were administered a test called the LOT-R, which measures a person's optimism and pessimism. Typical questions include, "In uncertain times, I usually expect the best," or "If something can go wrong for me, it will." The authors looked at dispositional optimism, which is the expectation that more good things than bad things will happen in the future. The study suggested that optimism had a protective effect against having a stroke -- optimists had fewer strokes than pessimists.

Previous studies have also suggested the health benefit of optimism. A 2009 study published in Circulation looked at 97,253 women who were tested for optimism and a cynical hostile attitude toward others. The most cynical and hostile women had a higher incidence of coronary heart disease and vascular death, while optimistic women had lower rates. Once again, being an optimist can have a protective effect, while being a pessimist can be detrimental to your health. This study is keeping in tune with the data on Type-A personalities, where hostility is also a lethal trait.

Another study tracked 6,958 students at the University of North Carolina from the mid 1960s to 2006. The pessimistic individuals had higher death rates and were more likely to utilize medical services and develop depression and poor physical health. Over a 40-year period, the death rate was 42 percent higher amongst the most pessimistic group.

The Chicken or the Egg

At an early age, we are confronted with the puzzling question, "Which came first, the chicken or the egg?" Similarly, we must ask whether being optimistic leads to better health or whether people with healthy lifestyles are more optimistic because they feel better? Others have suggested it is easier to be optimistic if you have a higher socioeconomic status, are better educated and are in shape and not obese. If we are "hard wired" for optimism, what can we do to avoid the "toxicity" of pessimism? If the glass is half empty, how do you fill the other half?

The answer is still out as to whether you can turn a pessimist into an optimist, or at least change their "habitual" way of thinking, but in light of the health data, you should make a concerted effort. In his 1990 book "Learned Optimism," Martin Seligman suggested people could change their false conceptions by challenging and disputing their beliefs and developing a realistic approach to the consequences of those beliefs. Others have suggested lifestyle changes like relaxation techniques, more sleep, a healthier lifestyle and more time with friends as keys to a more optimistic take on life.

Pessimism can be bad for your health, and it could lead to heart disease and strokes. You may not be able turn to yourself into a whistling, wide-eyed optimist, but it is worth the effort to shed yourself of cynical hostility.

Actually, just to pick the nit: that glass is about 2/3 empty. It is filled halfway up, but volume-wise it is filled less than half, or at least it's shape suggests that.

Optimists are made in the left frontal lobe..just make sure the optimist doesn't become a Manic personality -mood disorder or even bipolar..looking at the continuum

"Cheer up," they told me. "Things could be worse."

So I cheered up, and sure enough, things got worse.

Geez..... Well ...saying yes to the glass being half full MIGHT make you healthier says the title...or MIGHT NOT. That's the funny thing about the word "might"--it means an unknown. I've really learned a lot, or maybe not. My pessimistic life is now complete knowing that being positive might or might not make me healthier.

I always think of the glass completely full, the way I look at it is this: If you want to be optimistic do it all the way! Half full, half empty doesn't matter - but if you think it's full all the time, then it will be. Thoughts and specifically positive thoughts are very powerful, so of course it's very healthy to be optimistic.

What ever you think about the most is what always happens, so think positive no matter what, don't let bad surrounding trick you.

IT'S NOT HOW WE START IT'S HOW WE FINISH

It's not how we start it's how we finish
That lets others know how much we care.
We make our mistakes and pray to God
For all His blessings beyond compare.

God and Satan both whisper to every ear
For they know our souls control our passions.
The outcomes of life both joyful and sad
Teach which voice rewards or rations.

All Heaven's heroes except for Jesus
Had to be forgiven for their willingness to stray.
They let God down and paid the price
And their stories still relate today.

WHY I LOVE GOD


I love God because He was the first to love me
Lord of my heart and soul, my shepherd, teacher and guide.
He has taught me more than I could never learn in school
And salvation only comes through Jesus who suffered and died.

We’re always better off than we deserve
When we stop to recall how we have failed our Master.
We count God’s blessings and all our mistakes
And wonder how we escaped death, imprisonment or disaster.

God always loves us no matter our circumstance
As long as we continue to love Him in return.
He leads us from the dangers of misguided passions
By His grace, intervention and our willingness to learn.

Life on Earth is Heaven’s boot camp of resolve
All have a choice to heed or ignore God’s call.
When we act on our own and decline to trust Him
We endlessly agonize, procrastinate, stumble and fall.

You can lose the negativity and whining. I've found that taking time each day to count things I'm grateful for keeps the angst and depressive attitude(s) out of my head.It's not about being a Pollyanna and acting like all is well, it's just finding a balanced view of life.

I always knew singing in the shower and having my glass(es) of "something" in the evening kept my cholesterol (very) low and my blood pressure the same.

Maybe if we could all be well-paid Doctors like Richard we all wouldn't be "cynical hostiles".
It is funny how the Well-To-Do lecture people who aren't well off with articles like these.

Yeah we're angry!

The only thing this twisted American society respects is BILLS PAID ON TIME!
If you don't believe it, try not paying yours for a few months and see what happens to you.

Didn't bother reading. Sue me. The title says all I need to really know. And that would be: Is the glass half empty? Saying yes "might" make you healthier. I'm not against optimism, nor pessimism for that matter. I am skeptical, however, of many so-called expert's definitions and interpretations of character or personality traits of their fellow humans.

every night I take a tall gass of ice water to bed....when I drink it all, I get more....when I awake in the middle of the night and I see there is still water left, even a little, I get very happy.....

This article is next to useless since the good doctor fails to prescribe how to make this change. Telling us what some people have tried,e.g. meditation, is merely anecdotal advice, not science.

When one reads an article like this it feels that people have choices to become what they choose to be ie. a glass is half empty person understands the issue and can trun around into a glass half full person by just reading such an article. Just like people vary in height and in other physical and mental characteristics they also vary on how they look at themselves and the world. Some people are born curmudgeons and others are born bon vivants. This is also why life is so beautiful!
