Hey there welcome to LIFE NOGGIN.
Have you ever been so angry that you start to relate those cartoon characters who have steam coming out of their ears?
Or maybe you feel like your blood is boiling beneath your skin.
Even though you may know what the external cause of your anger is,
what's actually going on inside your body when you're angry.
That's what we're going to find out.
Imagine that you're driving on the freeway and somebody suddenly cut you off.
You will most likely get angry and either honk your horn,
or possibly give them a not so nice hand gesture. Admit it, we've all done it before.
Inside your brain, it admitted below which is response to outside stimuli
processes the car that cut you off, and coordinates the release of neurotransmitters,
called catecholamines.
These cause you to feel a burst of energy preparing you for physical action.
The hormones epinephrine and norepinephrine are also released, increasing your blood pressure.
Your heart rate increasing and your face may flush, the blood rushes to your extremities.
If you've seen someone so angry that they turned red as a lobster, this is why.
If you want to keep this anger at bay, you have to use your prefrontal cortex.
You can think of this as the area that can control you judgement.
And if you don't use your prefrontal cortex, you may act aggressively toward others.
Take Phineas Gage as an example.
In 1848 while at work, a tamping iron was shot through his left cheek and exited through the top of his head.
Somehow he survived, but his frontal lobe was severely damaged.
After his injury, he is said to have been fitful, irreverent and have the animal passions of a strong man.
Perhaps the damage to his frontal lobe destroyed his ability to control his behavior.
He was not only a new man, but also one incapable of self-constraint.
It's also important to note that constant chronic anger can greatly increase a person's chance of getting a heart disease.
like high blood pressure or heart attacks.
Anger and the heart are very connected.
This is because epinephrine and norepinephrine constrict your blood vessels, making your heart pump harder.
These two hormones also increase the amount of glucose and fatty acids in the blood.
The increased levels can lead to damage in artery walls and speed up the process of atherosclerosis.
When the fatty plaque builds up in arteries, it narrows them and increases the flow of oxygen-rich blood in the body.
This can lead to a heart attack, stroke or death.
But, fear not. There're healthy ways to control your anger,
such as meditation, anger management therapy, exercise or even just relaxing and doing something fun.
