Laughter

First of all when we talk about laughter we should know what it is. Researchers suggest that laughter is an audible expression or the appearance of happiness, or an inward feeling of joy and it may ensue from jokes, tickling or other stimuli. So, like we see people face with laugh every day, but they don't pore over why they are laughing. So, today I am going to talk about why we laugh and about benefits for our health.

The first thing that I want to talk about is what causes our laughter. There are two leading points: biological and psychological. So, when we talk about biological causes I can say that modern neurophysiology states that laughter is linked with the activation of the ventromedial prefrontal cortex, which produces endorphins after a rewarding activity. Research has shown that the limbic system is a primitive part of the brain that is involved in emotions and helps us with basic functions necessary for survival. Two structures in the limbic system are involved in producing laughter: the amygdale and the hippocampus. Talking about psychological causes it can be said that common causes are sensations of joy and humor, but a general theory that explains laughter is called the relief theory in which Sigmund Freud suggest that laughter releases tension and "psychic energy". This theory is one of the justifications of the beliefs that laughter is beneficial for one's health. This theory explains why laughter can be as a coping mechanism for when one is upset, angry or sad.
The second thing that I want to talk about is laughter benefits for our health. Like we know laughter is a powerful antidote to stress, pain, and conflict. Nothing works faster or more dependably to bring your mind and body back into balance than a good laugh. Moreover, laughter is good for our health because it relaxes the whole body, boosts the immune system, protects the heart, decreases pain, eases anxiety and fear, improves mood. So laughter has a lot of benefits for our health and if we want to be healthy what we should do is smile, when we hear laughter, move toward it, spend time with fun, playful people, and bring humor into conversations.

To summarize I want to say that laughter is an integral part of life, we are laughing every day and we should know that there are two leading points of our laughter: biological and psychological. Also we shouldn’t forget that laughter has a lot of benefits for our health and prolongs our life in three seconds, so what we need to do is smile, smile and one more time smile every day for everyone.
