Positive Thinking Can Benefit Your Mind and Body

For most of my career as a dietitian and health counsellor I have paid much attention to the deficiencies in my clients' diet and lifestyle choices and how these could be changed for the better. Over the years, however, I began focusing more on what went right in their lives and how their strengths could be utilized in order to overcome their weaknesses. You may say I applied (unknowingly) what is now known as "positive psychology."

When I say, "what went right in their lives," I do not necessarily mean whether they were successful at their work, were financially secure, or had stable marriages and relationships -- although these may be important aspects as well -- but rather, on a more intimate level, whether they had a sense of self-esteem, fulfillment, gratitude, purpose, and looked optimistically to the future.

This is in fact what practitioners of positive psychology are also most interested in. Their goal is to overcome existing negative thinking styles, mainly by fostering positive ones. They try to achieve this by having their clients recall pleasant past experiences, build on advantageous traits and characteristics, cultivate supportive relationships, and so forth. The desired end result is what proponents call "living the good life," which, again, is not simply to be equated with material wealth.

The "good life" is happy, engaged, and meaningful. To realize it, one must mobilize inherent strengths, thereby increasing positive emotions while decreasing negative ones, according to Dr. Martin E. P. Seligman, a professor of psychology at the University of Pennsylvania and author of several best-selling self-help books, who is widely credited as one of the founders and early developers of positive psychology as its own academic branch.

Traditional psychology has almost always been concerned with mental and emotional disorders and malfunctions and ways to treat them, he explains. By contrast, positive psychology adds an important emphasis on the human potential for building and maintaining highly functional and constructive lives.

A number of distinct theories have entered this relatively new field lately. Some focus on basic emotions like joy and happiness, others on the human capacity to create purpose and meaning. The ability to blissfully immerse oneself in one's work, to flourish while encountering challenges, or to stay resilient in the face of adversity -- these are all elements that can contribute to a person's well-being and are worthy of further exploration.

And the positive effects are not limited to the mind but benefit the body as well. Plenty of research has already shown that a positive attitude can be enormously advantageous for good health, and even longevity. One study from the Netherlands found that heart disease patients who maintained a generally optimistic outlook were able to slow down the progress of their illness and extend their life expectancy by several years.

Of course, the reason why some people continue to thrive while others quickly succumb in similar situations is still a mystery. However, clearly distinguishable ways of thinking seem to make at least some difference that can determine outcomes.

And no doubt, in my own work as a health counselor, I have also reaped the benefits from seeing the glass more often as half-full than half-empty. And because optimism tends to be contagious, there lies some healing power for my clients in that, too.
