Gallows humor（黑色幽默）seem like a mistake, or at least in poor taste. But psychologists say that gallows humor can be an important way to relieve stress. “Humor makes you feel in control and it can give you that feeling that everything is okay even when it's not,” says James M. Jones, a psychology professor at the University of Delaware.
Psychologists say that just because you're laughing doesn't mean you’re wasting time. Occasional teasing among colleagues, particularly if it revolves around things associated with the job, can boost creativity, departmental cohesiveness（凝聚力）and performance.
“There are a lot of stressors out there,” says Ed Dunkelblau, a psychologist with the Institute for Emotionally Intelligent Learning in Chicago. “But gallows humor is a way of making difficult things a little less difficult.”
This is true as long as the humor is used for the right purpose. The main point of it should be inspiring people --- not laughing at them. “Anything that would lift morale（士气）in terms of the company would be good humor,” says Thierry Guedj, a professor of business and psychology at Boston University. “Before you say or do anything, think about, ‘How is this helping my employees’ morale?’”
You want to give your employees and co-workers a sense of belonging, so don’t make observations that are aggressive. Most obviously, Dr Guedj says, don’t make comments about people’s physical appearance, or faith. If you have any doubt, it's appropriate, don't go through with it.
Or you can take aim at the one person you know won't be offended（冒犯）:Yourself. “If there's going to be a joke or story, it should be you,” Mr. Dunkelblau says. For example, if you're a marketing manager reviewing a failed campaign that you led, begin with a line like, “The guy who gave permission to this deal might just be looking for work next week.”
“People with the ability to laugh at themselves can give other people permission to laugh at themselves too,” Mr. Jones says. “And if you can laugh at yourself, you feel better about yourself.”
