②Rod Martin at the University of Western Ontario examined the relation-ship between a sense of humor and psychological wellbeing. He found individuals with a good sense of humor had higher levels of self-esteem (自尊), were more positive in the face of challenging life events, and had more self-protective ways of coping with stress
③However, this finding is only corelational. It could be that a good sense of humor fosters the positive qualities, and that high levels of self-esteem and a positive mindset may be what allows an individual to develop a good sense of humor. To prove it, researchers randomly appointed 55 adults to three courses: a humor group, a social group, and a control group. At the end of the courses, those in the humor group scored significantly higher on levels of emotional wellbeing and showed decreased levels of stress and anxiety. The researchers also tested the effects of attending parties as well as watching comedies and funny films. They found that these positive social activities also made these adults more humorous and welcome.
④Wellbeing in the workplace can also be increased by humor. Both Eric Romero and Kevin Cruthirds at the University of Texas found encouraging moments of jokes among colleagues were generally associated with increased work performance and decreased reports of stress. However, they also raise a caution: any positive result depends on the jokes in question. That the type of humor is key to its benefits clarifies why positive findings in this area are often weak or unclear. As some researchers wisely point out, the problem is that too few of them begin by defining clearly what humor is. He believes there are two types: adaptive and maladaptive (适应不良的).
⑤Adaptive humor encourages us to feel closer to others and better about ourselves, whereas maladaptive humor is self-defeating, rude and aggressive. Maladaptive humor leads only to lower self-esteem and a distance between you and your colleagues.
⑥The conclusion? Humor can definitely help you, not only with your mental wellbeing, but also with your colleague relationships - only if it's adaptive, self-enhancing and acceptable. All in all, kindness is the key.

【推荐3】As a historian who’s always searching for the text or the image that makes us re-evaluate the past, I’ve become occupied with looking for photographs that show our Victorian ancestors smiling. I’ve found quite a few, but disappointingly my collection of ‘Smiling Victorians’ makes up only a tiny percentage of the vast ocean of photographic portraits (肖像画) created between 1840 and 1900, the majority of which show sitters posing like marble statues in front of painted backdrops, or staring absently into the middle distance. How do we explain this trend?
During the 1840s and 1850s, in the early days of photography, exposure time was shockingly long: the daguerreotype photographic method (银版照相法) could take several minutes to complete, resulting in unclear images as sitters shifted position or adjusted their arms and legs. So a blank stare instead of a fixed smile became the norm. But exposure time was much shorter by the 1880s. Natural smiles were relatively easy to capture by the 1890s, so we must look elsewhere for an explanation of why Victorians still hesitated to smile.
One explanation might be the loss of dignity displayed through a cheesy smile. “Nature gave us lips to cover our teeth, ” ran one popular Victorian saying, indicating an easy-to-ignore fact that before the birth of proper dentistry, mouths and irregular and yellow teeth were like peas and carrots. A flashing set of healthy and clean, regular pearly white teeth was a rare sight in Victorian society, the preserve of the super-rich.
A toothy smile, especially when there were gaps or blackened teeth, lacked class: Drunks, beggars, and some music hall performers might makes faces and smile with a laugh as wide 8s Lewis Carroll’s gum-exposing Cheshire Cat, but it was not a becoming look for properly brought-up people. Even Mark Twain, a man who enjoyed a hearty laugh, said that when it came to photographic portraits there could be “nothing more stomach-turning than a silly, foolish smile fixed forever”.
