Posted on August 23, Nervousness is not just a state of mind - for many people feeling nervous is accompanied by all sorts of physical sensations too. But why should thinking about an upcoming presentation, sporting event or even a date make us feel this way? The autonomic nervous system is the system in the body responsible for control of the bodily functions not consciously directed, such as breathing, the heartbeat, and digestive processes. The autonomic nervous system has two components, the sympathetic nervous system and the parasympathetic nervous system. The parasympathetic nervous system promotes the rest-and-digest response that calms the body down after the danger has passed.
So, what exactly is going on down there? Getting nervous, excited or sexually aroused all stem from the same belly-to-brain connection. It just depends on how you interpret the feeling, Dr. Daniel Amen, psychiatrist and neuroscientist, tells NBC. When a stimulus is encountered — be it a high-stakes job or a particularly attractive human — it activates the parts of the brain that process pleasure, mainly the basal ganglia of the cerebrum.
Why we get butterflies in our stomach when we're nervous?
These centers send a message down to the stomach through the vagus nerve, which activates the feeling in our gut. The salience network is a huge collection of regions that determine which stimuli is worthy of our attention, according to the textbook Salience Network of the Human Brain.
Once the network identifies the stimuli, it evaluates it and prepares an appropriate neural response. It regulates our flight-or-fight response, essentially preparing us for whatever may be about to happen, according to Refinery Major triggers for the ANS are fear and anxiety, which when stimulated result in an adrenaline rush and the release of stress hormone norepinephrine.
As a result, the heart starts pumping blood to the extremities to prepare them for either flight or fight, leaving the gut devoid of blood, which can create a sensation that feels like a flutter. One explanation for the ANS kickstarting at the sight of a potential partner is that we associate vulnerability with being in a relationship, which can create an anxiety trigger, Jean Fitzpatrick, a NYC-based pre-marital and marital therapist, told Refinery Nicole Prause, psychophysiologist, told NBC.
We often interpret the feeling of butterflies fluttering, especially with regard to another human, as a of excitement and passion. Interestingly, these flutters have nothing to do with true love, which Dr. The lack of flutters means that you are finally comfortable enough around them not to feel anxious.
