Hi, I'm Omar Saad here for About.com, and today we're going to take a look at the benefits of optimism, based on an article from About.com's Stress Management site. Whether suffering a minor bump in the road or a big setback, it seems as though you can't get an optimist down. But does this way of thinking actually produce positive results? Let's take a closer look.The most outwardly obvious benefit of being an optimist is happiness. Optimistic people always seem to be in a good mood or have a smile on their face. That's because optimists believe in themselves and believe that good things are always around the corner for them.Another benefit of optimism is an innate sense of persistence, which is a common characteristic found in optimistic people. Persistence, born out of a belief that success is on the horizon, can become a self-fulfilling prophecy for optimists. Examples can be found throughout society, from the optimistic businessman who pushes through tough times to find eventual success, to the optimistic actor who sticks it out long enough to get their big break.Perhaps this perseverance may be the reason why optimists seem to experience greater achievements in life. As cited on About.com’s Stress Management site, studies have shown that optimism among athletes and sports teams leads to better performance.Another purported benefit of optimism is better health, both physical and emotional. In another study, this time of Harvard University students, those who were optimists at age 25 were significantly healthier at the ages of 45 and 60 than their pessimistic counterparts.Furthermore, it's believed that optimists experience less stress than pessimists, because of a belief in themselves and the expectation of good things heading their way. This is key to one's health, as it is thought that consistently high stress levels can contribute to negative health consequences down the road. Whether it’s life success, good physical and emotional health, or just a general feeling of happiness, the benefits of optimism seem to enhance one's quality of life.Thanks for watching.
