Crying helps people recover from strong positive emotions with tears of joy, suggests a study.
Famous psychologists and researchers have concluded that tears roll down when people are overwhelmed with strong positive emotions and people who behave in a such a way seem to recover better than those strong emotions.
They found that individuals who express negative reactions to positive news were able to moderate intense emotions more quickly.
They also found people, who are most likely to cry at their child's graduation are most likely to want to pinch a cute baby's cheeks.
There is also some evidence that strong negative feelings may provoke positive expressions.
For example, nervous laughter appears when people are confronted with a difficult or frightening situations, and we also smile during extreme sadness.

"These insights advance our understanding of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together," she concluded.
