We've all experienced a "good cry"． Shedding （流） some tears can often make us feel better and help us put things in perspective． But why is crying beneficial? And is there such a thing as a "bad cry"?
The researchers analyzed the detailed accounts of more than 3,000 recent crying experiences and found that the benefits of crying depend entirely on the what, where and when of a particular crying episode （一段经历）． The majority of persons reported improvements in their mood following a short period of crying． However, one third reported no improvement in mood and a tenth felt worse after crying． Criers who received social support during their crying episode were the most likely to report improvements in mood．
Research to date has not always produced a clear picture of the benefits of crying, in part because the results often seem to depend on how crying is studied． The researchers note several challenges in accurately studying crying behavior in a laboratory setting． Volunteers who cry in a laboratory setting often do not describe their experiences as making them feel better． Rather, crying in a laboratory setting often results in the study participants feeling worse;  this may be due to the stressful conditions of the study itself, such as being videotaped or watched by researchers． This may produce negative emotions, which neutralize （使无效） the positive benefits usually connected with crying．
However, these laboratory studies have provided interesting findings about the physical effects of crying． Criers do show calming effects such as slower breathing, but they also experience a lot of unpleasant stress, including increased heart rate and sweating． What is interesting is that bodily calming usually lasts longer than the unpleasant． The calming effects may occur later and overcome the stress reaction, which would account for why people tend to remember mostly the pleasant side of crying．
Research has shown that the effects of crying also depend on who is shedding the tears． For example, individuals with anxiety or mood disorders are least likely to experience the positive effects of crying． In addition, the researchers report that people who lack insight into their emotional lives actually feel worse after crying．
