why do we jump when watching a scary movie

БWhoБs there?! Б
БShow yourself! I have a gun! Б (The girl quietly went towards the door and turned the knob silently. As soon as the door was opened, she saw no one except the branches of the tree rattling on the glass windows as they were blown by the cold wind. The girl immediately lets out a sigh of relief. But as she closed the door, the masked killer suddenly jumped out from behind her and grabbed her neck! ) БAaaaarrgghhh! Б (The girlБs cry did not matter anymore because the killer has successfully pierced his foot long dagger directly into the girlБs heart! After only a few seconds, the girl was already lying on the floor. Her eyes were wide open, but her body was unmistakably lifeless! ) This is the typical scenario whenever we watch our favorite horror or suspense movies. We sometimes even cover our eyes in order to prevent seeing the attack of the monster or the killer in the movie. We even shudder as we feel the cold sweat trickling down our skin.


Our heart is also unusually beating extremely fast as we witness the escape of the movie star away from the protagonist. Nevertheless, have we ever actually wondered why our bodies react in such way? Have we ever seriously thought about why do we jump when watching a scary movie? The answer to these questions is primarily the result of our fight and flight response. This response occurs as an aftermath of the reaction of our sympathetic nervous system. This is basically part of our nervous system that we cannot voluntarily control. Our SNS reacts whenever a stimulus is being detected by our bodies. In this case, the horror movie serves as our bodyБs stimulus. This stimulus is then perceived by our body as threatening thus signaling the different glands in the body to produce or release hormones appropriate with the situation. An example of this hormone is the adrenaline which is produce by the adrenal glands. This adrenaline goes through our bloodstream and signals the other organs and tissues in our bodies to respond appropriately with the situation.


An example of this appropriate response is when the heart increases its beating rate in order to pump more blood and oxygen to the other organs of the body. This also includes dilatation of the pupils, relaxation of the bladder, as well as the sudden loss of vision and hearing. All of these reactions are the result of our fight and flight response to a potentially threatening stimulus. This is the reason why we jump when watching a scary movie or whenever we witness something horrifying. A movie that can make us jump out of the seat is sometimes the basis of film critics to determine whether or not the horror film is successful in its goal of frightening the audience. So next time we try to watch a horror flick, we must first make sure we have the guts to do it! This is a response from your sympathetic nervous system, a part of your nervous system that is not under your direct control.


When your senses take in stimuli (like a scary movie) that your brain perceives as being threatening, the SNS produces the flight or flight response. Nervous system signals are sent out to certain glands (such as the adrenals located by the kidneys) that release hormones into your blood stream. One of the major hormones that is released by the adrenal glands in response to these signals is epinephrine (also called adrenaline). Adrenaline courses through your blood stream and affects the functioning of a large number of organs and tissues, including the heart and lungs. After a time, the body breaks down the hormone, so its levels decrease in the body. In addition, the parasympathetic nervous system sends signals out to the body to essentially calm down and return to resting state. br / br / br / br / br / br / br / br / br / br / br / br / br / br / br / br / br / br / br / br / br / br / This answer is by Jessica238 br / br / br / br / br / br / br / This is a response from your sympathetic nervous system, a part of your nervous system that is not under your direct control.
