“Hopefulness and confidence about the future or success of something.” That’s the Oxford English Dictionary’s definition of optimism. Positivity, meanwhile, is the practice of having this sunny, constructive attitude as you move through life. Is your reaction to such words the sort of enthusiastic pep embodied by Elle Woods? Or do you need to suppress an eye-roll vigorous enough to risk retina strain? If it’s the latter, you’re not alone in your cynicism. And yet, those expressive glass-half-full types – the ones who’d be sorted into Hufflepuff and not kick off about it – may be having the last belly laugh. The try-hards. The keenos. The optimists.
In a study published last year, researchers found that optimistic people are more likely to lead lengthier lives, with a predicted lifespan up to 15 percent longer than the least optimistic among us and a higher chance of living to 85 and older. It follows research published in the British Medical Journal that found optimistic people are more likely to have better cardiovascular health, with scientists positing that this may be partly explained by a correlation between feeling positive and looking after your health. As for the impact of a hopeful outlook on your mental health, perhaps unsurprisingly, a review of research found optimists have a lower risk of depression, while pessimism makes you more susceptible to low mood.
