why do some people cry when they laugh

Have you ever found yourself or witnessed someone laughing to the point of tears? This seems like a conflicting emotional response as tears typically signify sadness, while laughter is an expression of joy. Scientists have not completely pinned down why our bodies produce tears when we laugh too hard, but they have a few theories. Recently, Yale University psychologist, Dr. Oriana R. AragГn, led a research study that evaluated why we experience certain physical reactions to emotional situations. Her team defined these seemingly inappropriate responses (crying while laughing, nervous laughter, etc. ) as dimorphous expressions. According to Dr. AragГn, we cry when we laugh so hard because the body is trying to regulate itself in response to strong emotions. Some believe crying while laughing occurs because both reactions are a result of increased emotion. By crying, the body attempts to return to a regular level of functioning.


Some evidence suggests the same part of the brain controls both crying and laughing. For example, a condition called the Pseudobulbar affect (PBA) causes people to have uncontrollable outbursts of crying or laughter because of neurological conditions or brain injuries, leading scientists to believe crying and laughter are run by the same area of the brain. Others theorize people cry while laughing because of too much pressure around the tear ducts due to the body shaking during strong laughter. These tears are called reflex tears, which occur when the eyes come in contact with an irritant such as a strong gust of wind or the aroma of a freshly sliced onion. It is important to note these are different from emotional tears, which are produced in response to an experienced emotion, such as sadness or anxiety.


Both crying and laughing have positive emotional benefits. The emotional tears produced from crying are biologically different from other tears our eyes produce. They contain hormones and endorphins in response to stress, which aid in regulating emotions. This is why people say they feel relieved after crying. Similarly, laughter decreases stress hormones and triggers the release of endorphins, which also creates a feel-good effect. Next time you see someone doubled over from laughter with tears streaming down their face, you ll know that their eyes are functioning normally. If you or someone you know experience frequent tears that are not related to an emotional reaction,. We can help.
Hi u12tsangv interesting question! We usually associate crying with being sad, but of course we also cry when we laugh too. In fact, crying tends to happen whenever we are particularly emotional.


Being sad and happy are completely different things, but we re very emotional when we re very happy and very sad. Crying is an intense emotional response, so when we are overwhelmed with feelings, our feelings show as tears. Some scientists think that we cry when we laugh because when we laugh we screw up our faces so much that we put so much pressure on our tear ducts that we force the tears out. Tears also accompany the body s return to a more stable, balanced state after we have been very excited. So after a big laugh, tears are a sign that the body is returning to normal. Scientists have studied tears and found that they contain lots of stress hormones which can be released either caused by stress or by pleasure. So when we cry, we are getting rid of all our excess stress hormones from our bodies. That s why we always feel better after a good cry.
