Laughing for Your Health

Research on the influence of emotions on various pathologies dates back to ancient Greece, where it was already established that there was a relationship between mind and body. Since then, research has continued on how certain emotions, such as anger, can affect psychophysiological disorders, such as heart disorders. Although more studies are focused on the effects of negative emotions on health and illness, we know that there are many benefits of laughter.

Laughter causes the activation of specific brain areas, causing us to feel better, see problems less serious, and feel less stressed, happier, and more energetic. Freud, the father of Psychoanalysis, has already mentioned that “letting out a laugh” is a mechanism used by our body to release tension and anguish.

  • It reduces stress and anxiety, when we laugh, we secrete a hormone called “endorphin,” associated with the feeling of happiness. The more we laugh, the more endorphin we generate, thereby increasing the feeling of well-being. In addition, when we laugh, we also secrete dopamine and serotonin, substances that fight mood disorders such as stress, anxiety, and depression. Laughter also reduces the level of cortisol associated with stress and regulates adrenaline levels, a hormone that helps our body cope with alarm and anxiety situations.

Types of Laughter

  • Spontaneous or genuine laughter: It arises naturally from the expression of positive emotions or by contagion through mirror neurons’ action.
  • Rehearsed or unconditional laughter: It occurs intentionally and does not require any external stimulus to produce it. It is not associated with thoughts or emotions; that is, it is not associated with humor.
  • Stimulated laughter: It is a consequence of the physical or reflex action of some external stimuli on the facial muscles or other body points with neurological sensitivity that triggers laughter, for example, tickling.
  • Induced laughter: It is generated as the primary or secondary product of the intake of drugs or drugs. It is hollow and shallow.
  • Pathological laughter: There is a lack of control over its expression, duration, or intensity; it is not associated with specific stimuli, nor is it produced by emotional changes. It is a consequence of lesions in the central nervous system due to neurological diseases or because it is present in certain mental disorders.

For laughter to generate physical and psychological benefits, it has to be spontaneous and authentic.It is what is known as the Duchenne Smile, which is the product of an impulse that responds to processes in the limbic system, the area of ​​the brain where emotions are processed. However, a false, forced, or voluntary smile originates in the motor cortex, the brain area that “sends messages” to our muscles to move.

However, a rehearsed laugh also has some benefits compared to spontaneous, since it is more accessible, requires little effort, is independent of personal characteristics or socioeconomic context, requires less emotional involvement, and can lead to spontaneous laughter. For all this, laughter can also be used as a therapeutic element in laughter therapy.
