Effects of Stage Fright
When someone starts to feel the sensation of being scared or nervous they start to experience anxiety. According to a Harvard Mental Health Letter, "Anxiety usually has physical symptoms that may include a racing heart, a dry mouth, a shaky voice, blushing, trembling, sweating, and nausea" (Beyond Shyness). It triggers the body to activate its sympathetic nervous system. This process takes place when the body releases adrenaline into the blood stream causing a chain of reactions to occur. This bodily response is known as the "fight or flight" syndrome, a naturally occurring process in the body done to protect itself from harm. “...The neck muscles contract, bringing the head down and shoulders up, while the back muscles draw the spine into a concave curve. This, in turn, pushes the pelvis forward and pulls the genitals up, slumping the body into a classic fetal position" (Cyphert).
In trying to resist this position, the body will begin to shake in places such as the legs and hands. Several other things happen besides this. Muscles in the body contract causing them to be tense and ready to attack. Second, "blood vessels in the extremities constrict" (Cyphert). This can leave a person with the feeling of cold fingers, toes, nose, and ears. Constricted blood vessels also gives the body extra blood flow to the vital organs.
In addition, those experiencing stage fright will have an increase in blood pressure, which supplies the body with more nutrients and oxygen in response to the "fight or flight" instincts. This, in return, causes the body to overheat and sweat. Breathing will increase so that the body can obtain the desired amount of oxygen for the muscles and organs. Pupils will dilate giving someone the inability to view any notes they have in close proximity, however, long range vision is improved making the speaker more aware of their audience's facial expressions and non verbal cues in response to the speaker's performance. Lastly, the digestive system shuts down to prepare for producing energy for an immediate emergency response. This can leave the body with the effects of dry mouth, nausea, or butterflies (Cyphert).

“Like the effects of industrial pollution ... the AIDS crisis is evidence of a world in which nothing important is regional, local, limited; in which everything that can circulate does, and every problem is, or is destined to become, worldwide.”
—Susan Sontag (b. 1933)
“The best road to correct reasoning is by physical science; the way to trace effects to causes is through physical science; the only corrective, therefore, of superstition is physical science.”
—Frances Wright (1795–1852)
“The post-office appeared a singularly domestic institution here. Ever and anon the stage stopped before some low shop or dwelling, and a wheelwright or shoemaker appeared in his shirt- sleeves and leather apron, with spectacles newly donned, holding up Uncle Sam’s bag, as if it were a slice of home-made cake, for the travelers, while he retailed some piece of gossip to the driver, really as indifferent to the presence of the former as if they were so much baggage.”
—Henry David Thoreau (1817–1862)
“Twenty-two weeks the men were out as the strike moved into winter. It was strange to go out into the street and find the men there in the daytime. It had a feeling of fright in it. And always the mood of the men grew uglier as empty bellies and desperation began to conquer reason. Any man who was not their friend became their enemy. They knew my father had opposed the strike, and now it was they who opposed him.”
—Philip Dunne (1908–1992)
