Your heart jumps and you suddenly become excruciatingly aware of a little too much perspiration. Words struggle to form in your mouth as you attempt to answer an unexpectedly tough question in the monthly project meeting you’re hosting.
Well hey there, norepinephrine! How nice to see you again… What you’re feeling is the very noticeable effects of sudden neurochemical changes, like our old friend norepinephrine.

How the brain responds to surprising events
Unexpected outcomes trigger release of noradrenaline, which helps the brain focus its attention and learn from the event.
How to Balance Norepinephrine Levels Naturally
Norepinephrine is a dual-purpose chemical messenger that acts as both a stress hormone and a neurotransmitter. It’s sometimes called noradrenaline, especially in the United Kingdom, but here in the US, norepinephrine is the preferred term.
Summary of Noradrenaline or Norepinephrine
As a neurotransmitter, NE passes nerve impulses from one neuron to the next. It’s the primary neurotransmitter in the sympathetic nervous system where it works on the activity of various organs in the body to control blood pressure, heart rate, liver function, and many other functions. As a hormone, norepinephrine is released into the bloodstream by the adrenal glands and works alongside adrenaline (also known as epinephrine) to give the body sudden energy in times of stress, known as the “fight or flight” response.

Norepinephrine interacts and works synergistically with other biochemicals such as dopamine, serotonin, oxytocin, acetylcholine, melatonin, GABA, adenosine, cortisol, insulin, glucagon, and adiponectin.
Noradrenergic Synapse
First identified in the 1940s by Swedish physiologist Ulf von Euler, norepinephrine, also known as noradrenaline, is a neurotransmitter of the brain that plays an essential role in the regulation of arousal, attention, cognitive function, and stress reactions. It also functions as a hormone peripherally as part of the sympathetic nervous system in the “fight or flight” response.
Norepinephrine
Norepinephrine being released from adrenal glandNorepinephrine, also referred to noradrenaline, is a chemical messenger. It functions both as a neurotransmitter and a hormone within the body and is released in response to stress.
Norepinephrine vs. Epinephrine: What’s the Difference?
Norepinephrine activates mostly the alpha receptors in arteries; it does exert its effects on beta receptors, though it is a lot less significant. Stimulating the alpha receptors leads to vasoconstriction (narrowing of the blood vessels), which raises the arterial blood pressure. Along with epinephrine, norepinephrine initiates responses to improve your survival during a fight-or-flight situation.
Norepinephrine's Role in Treating Mood Problems
Medications that inhibit the reuptake of norepinephrine and serotonin (which is another neurotransmitter) are called serotonin-norepinephrine reuptake inhibitors (SNRIs). By inhibiting the reuptake of these two neurotransmitters, SNRIs essentially increase the levels of norepinephrine and serotonin in the brain
Norepinephrine: How to Boost This Important Stress Hormone
You’ve probably heard of adrenaline (or epinephrine) before, but what about another similar hormone called norepinephrine? Like adrenaline, it’s produced during the body’s natural “fight or flight” response and works as one of the body’s first responders to stressful situations. The hormone also works as a vasoconstrictor, and the FDA has approved its use for blood pressure control and as an adjunct in the treatment of cardiac arrest for people with severely low pressure.
The Norepinephrine Molecule
The prefix nor-, is derived from the German abbreviation for "N ohne Radikal" (N, the symbol for nitrogen, without radical), referring to the absence of the methyl functional group at the nitrogen atom of epinephrine.
What Is Norepinephrine?
Norepinephrine is both a chemical messenger from your central nervous system (CNS) and a stress hormone released from within your adrenal glands. It regulates numerous internal functions that keep your brain and body running efficiently.

Neurotransmitters
Norepinephrine is a neurotransmitter that is important for attentiveness, emotions, sleeping, dreaming, and learning. Norepinephrine is also released as a hormone into the blood, where it causes blood vessels to contract and heart rate to increase.
