Norepinephrine stimulates an increase in anxiety, alertness, and arousal during a stress response.

<h3>What is norepinephrine? </h3>
  • Norepinephrine, commonly known as noradrenaline, is a neurotransmitter and a hormone.
  • It performs the role of a neurotransmitter, a chemical messenger that helps nerve messages go from one nerve cell, muscle cell or gland cell to another.

<h3>When norepinephrine levels are high, what happens?</h3>
  • An excessive amount of norepinephrine can cause organ stress, anxiety, high blood pressure, a rapid heartbeat and headaches, high blood sugar and insomnia.
  • Additionally, drug withdrawal, chronic kidney illness, and psychological conditions like PTSD can result in high norepinephrine levels.
  • The amygdala, a region of the brain associated with creating behaviors connected to fear, is activated by norepinephrine.
  • The hippocampus and striatum's capacity to store traumatic memories for a long time is also improved by the amygdala.

Norepinephrine stimulates an increase in anxiety, alertness, and arousal during a stress response.

This physiological state consists of heightened brain activity, Rapid Eye Movement (REM), increased breathing, a temporary paralysis of  the body and genital engorgement. Through experiments, they confirmed that these physiological observations were the result of the person being  in the dream state.
