Research confirms that laughter plays an important role in human life. Fun and pleasant surprises add new texture to the structure of daily life. To some, a cheerful mood, accompanied by a smile and laughter, may seem like silly behavior. But in fact, laughter that arises as a response to funny events, requires a lot of concentrated work from the body. It activates many areas of the brain, most notably those parts of it that control motor, emotional, cognitive, and social processing.
For the first time, laughter and smile appear in infancy. It helps to develop the baby's upper body muscles and strength. Laughter is not just a special way of breathing. It uses combinations of facial muscles that are often associated with eye, head, and shoulder movements.
Then the motor cortex that controls the muscles of the face, the frontal lobe, which is responsible for understanding the context, and the limbic system, which makes up models of positive emotions, enter the process. The sequential inclusion of this entire circuit is aimed at strengthening neural connections.
It helps a healthy brain to coordinate its activities. Through the manifestation of emotions, the neural pathways responsible for joy and fun are activated. A person's mood improves, the reaction to stress becomes less intense. Scientists found that laughter controls serotonin levels in the brain, a process similar to the effects of antidepressants.
The brain minimizes its reaction to negative moments by limiting the release of hormones such as cortisol. The peculiarity of cortisol is that over time it can wear out the cardiovascular system, destructively affect the immune and cardiovascular.
Laughter was recognized as an antidote to stress, and it, in turn, weakens these systems and increases their vulnerability to disease.
