Hormone For Your Fight Or Flight Responses - Norepinephrine

Any medical newspaper or a health magazine will probably have adrenaline or epinephrine mentioned when it comes to taking care of health. However, not many are aware of this hormone called norepinephrine. Just like adrenaline, the body is able to produce norepinephrine as a natural fight or flight response. It works as the body’s first responders towards stressful situations. 

Apart from other functions that this hormone is capable of performing, it acts as a primary vasoconstrictor. The leading food departments in the world have approved the usage of norepinephrine for blood pressure control, for treating cardiac arrest and people who suffer from low blood pressure. 

Overusing norepinephrine supplements may trigger negative conditions such as:

  • Anxiety 
  • Sleep difficulties 
  • Brain fog 

It is important to keep the stress hormone levels in check by reducing the daily stress levels, regular exercise and maintaining a healthy body weight. It's best to remove gluten from the diet along with sugar and processed foods. Although they might seem to make you happy while eating, the resultant outcome is always negative. 

Understanding Norepinephrine

Also known as the noradrenaline hormone, it is a neurotransmitter belonging to the class of catecholamines. When a person undergoes physical and emotional stress catecholamines are released into the blood as a response of the immune system. Dopamine releases norepinephrine which is further released from the medulla into the brain. 

The Adderall medulla is responsible for synthesizing dopamine, also known as the happy hormone. Dopamine itself works as a neurotransmitter of the central nervous system and the sympathetic nervous system. Norepinephrine is released from noradrenergic neurons. 

Being a neurotransmitter, norepinephrine acts by sending signals between the nerve cells. They are responsible for activating Alpha 1 receptors which construct the natural walls and increase blood pressure so that a healthy blood flows back to the heart. 

Norepinephrine also acts as a stress hormone and as a vessel active agent, it is known to narrow down blood vessels, thereby increasing the blood pressure. When the brain is triggered by a stressful situation, either emotional or physical, this hormone is released into the blood.

This increases the heart rate and blood pressure during the body’s natural fight or flight response thereby, increasing the release of glucose into the blood. 

Benefits Of Norepinephrine

1. Increased Arousal And Alertness

Being a primary neurotransmitter, norepinephrine increases alertness, boosts the mood and is also responsible for arousal in humans. The normal hormonal levels make a person focus and concentrate better. 

Low norepinephrine levels lead to conditions such as ADHD. Dopamine and norepinephrine together make a person focus better on everyday tasks. Medications used in treating and improving ADHD increase the levels of Dexedrine, Adderall, Norepinephrine and Ritalin. 

2. Improve Depression Related Symptoms

The underlying pathophysiology of depression includes disturbances in the levels of dopamine, serotonin and norepinephrine levels, which are the primary happy neurotransmitters of the central nervous system. 

Evidence proving that noradrenaline responsible for depression is abundant. All of these play a determinant role in regulating motivation, intellect, cognition which are important functions at being socially active. 

3. Better Sleep

Antidepressant medications that are signaled towards treating insomnia, target norepinephrine for sleep. It has been indicated in research and studies, that the neurotransmitter involved in increasing the impact and efficacy of sleep-promoting medications is norepinephrine. 

Having the right amount of norepinephrine hormone in the body promotes better sleep however, too much arousal can also cause sleep issues.

4. Blood Pressure

Being peripheral, vasoconstrictor norepinephrine has the ability to narrow blood vessels and increase the pressure. People suffering from low blood pressure can normalize lifestyle changes and health. 

For those who suffer from symptomatic high potential, can use medicines that increase norepinephrine levels in the body. This is because symptomatic hypertension is usually unresponsive to home remedies like increased water intake and patience.

Norepinephrine, as a neurotransmitter is also used in intensive care units to treat septic shock. Septic shock is a severe infection that leads to low blood pressure levels and causes organ failure.

5. Deficiency Of Norepinephrine Symptoms

When the neurotransmitter levels helping the central nervous system and the sympathetic nervous system of the body go down below the normal level, a norepinephrine deficiency takes place. People suffering from poor nutrition, chronic stress and those taking medications may develop deficiency because the body begins to produce less norepinephrine than what is required. 

This can contribute to:

  • Increased fatigue of the mind in the day 
  • Migraine 
  • Fibromyalgia 
  • Restless leg syndrome 
  • Hypoglycemia 
  • Lack of interest 
  • Low energy 

Patients suffering from vascular thrombosis should not be advised to take epinephrine hormones, because the vasoconstriction effect will increase the area of ischemia and infarction in the heart. 

6. Boost Norepinephrine Levels Naturally

Typically, norepinephrine reuptake inhibitors are common prescription drugs used for treating depression. In some cases, doctors may also prescribe amphetamines for treating ADHD symptoms. The side effects of antidepressants do not go unnoticed and may result in:

  • Restlessness 
  • Stomach upset 
  • Suicidal thoughts 
  • Headaches 

In some people, the epinephrine levels can be treated naturally, like:  

  • Trying to get enough sleep and exercising regularly to boost the hormones. 
  • When a person conducts regular exercises, brain activities increase automatically. This has a major impact on normalizing the stress hormone levels. 
  • Another way to boost the levels of norepinephrine in the body is to increase dopamine. Dopamine acts as a precursor for the important neurotransmitter supplements that boost dopamine which include amino acids like tyrosine and phenylalanine. 

An intravenous infusion is made of norepinephrine in patients who suffer from Sepsis or Hypertension and typically administer them continually until the hormonal levels are balanced.
