Adrenaline, also called epinephrine, is a hormone released by your adrenal glands and some neurons. The adrenal glands are located at the top of each kidney. They are responsible for producing many hormones, including aldosterone, cortisol, adrenaline, and noradrenaline. Adrenal glands are controlled by another gland called the pituitary gland.
Introduction to Adrenaline
The adrenal glands are divided into two parts: outer glands (adrenal cortex) and inner glands (adrenal medulla).
The inner glands produce adrenaline.
Adrenaline is also known as the
It’s released in response to a stressful, exciting, dangerous, or threatening situation.
Adrenaline helps your body react more quickly.
It makes the heart beat faster, increases blood flow to the brain and muscles, and stimulates the body to make sugar to use for fuel.
When adrenaline is released suddenly, it’s often referred to as an adrenaline rush.
What happens in the body when you experience a rush of Adrenaline?
An adrenaline rush begins in the brain.
When you perceive a dangerous or stressful situation, that information is sent to a part of the brain called the amygdala.
This area of the brain plays a role in emotional processing.
If danger is perceived by the amygdala, it sends a signal to another region of the brain called the hypothalamus.
The hypothalamus is the command center of the brain.
It communicates with the rest of the body through the sympathetic nervous system.
The hypothalamus transmits a signal through autonomic nerves to the adrenal medulla.
When the adrenal glands receive the signal, they respond by releasing adrenaline into the bloodstream.
Activities that cause Adrenaline rush
Although adrenaline has an evolutionary purpose, some people take part in certain activities just for the adrenaline rush. Activities that can cause an adrenaline rush include:
Watching a horror movie
Cage diving with sharks
White water rafting
Symptoms of an Adrenaline rush
An adrenaline rush is sometimes described as a boost of energy. Other symptoms include:
Rapid heart rate
Decreased ability to feel pain
Increased strength and performance
Feeling jittery or nervous
How to control Adrenaline?
It’s important to learn techniques to counter your body’s stress response.
Experiencing some stress is normal, and sometimes even beneficial for your health.
But over time, persistent surges of adrenaline can damage your blood vessels, increase your blood pressure, and elevate your risk of heart attacks or stroke.
It can also result in anxiety, weight gain, headaches, and insomnia.
To help control adrenaline, you’ll need to activate your parasympathetic nervous system, also known as the
The rest-and-digest response is the opposite of the fight-or-flight response.
It helps promote equilibrium in the body, and allows your body to rest and repair itself.
Try the following:
Deep breathing exercises
Yoga or tai chi exercises, which combine movements with deep breathing
Talk to friends or family about stressful situations so you’re less likely to dwell on them at night; similarly, you can keep a diary of your feelings or thoughts
Eat a balanced, healthy diet
Limit caffeine and alcohol consumption
Avoid cellphones, bright lights, computers, loud music, and TV right before bedtime
