  • Hey there, welcome to LIFE NOGGIN.

  • Have you ever been so angry that you start to relate to 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 gonna find out.

  • Imagine that you are driving on a freeway and somebody suddenly cuts 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, the amygdala, which responses 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 increases and your face may flush as the blood rushes to your extremities.

  • If you have ever seen someone so angry that they turn red as a lobster, this is why.

  • If you want to keep this anger at bay, you'll have to use your prefrontal cortex.

  • You can think of this as the area that controls your 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 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 the arteries, it narrows them and decreases the flow of oxygen-rich blood to the body.

  • This can lead to a heart attack, stroke or death.

  • But, fear not, there are healthy ways to control your anger, such as meditation, anger management therapy, exercise or even just relaxing and doing something fun.

  • Like watching a few LIFE NOGGIN videos.

  • So tell us, what is one thing that makes you angry?

  • And what do you do to get over that feeling?

  • Make sure you come back every Monday and Thursday for a brand new video.

  • And if you want even more LIFE NOGGIN, check out these videos we did on the science of happiness and the signs of depression.

  • You can also follow us on Facebook and Twitter.

  • I'm Blocko. This has been LIFE NOGGIN.

  • Stay calm and don't forget to keep on thinking.
