What Happens To You During a Car Accident?

Understanding Survival Traits and Human Fight or Flight Physiology During and After a Car Accident

Have you ever been in a car accident and felt an extreme sense of urgency take over your body giving you the ability to react quickly to danger?

Or after a collision you walk away pain-free claiming you haven't suffered any injuries?

Many patients report auto accident injuries arising 2 to 3 days after the incident and often leave a crash reporting no injuries.

It's also common for people to describe a car crash in slow motion, know as slow motion perception.

What causes our bodies and minds to react to threatening events in this way? What is the science behind this and does this protect us from harm?

Natural hormones are secreted throughout the body when we undergo some traumatic event. Other activities that can spark these chemical reactions include bungee jumping, high altitude, nail-biting football match, bike stunts, and even watching a movie or reading a book.

Often we don't think twice about these heightened senses, but when our lives are threatened we develop an instinctive defense against danger.

Experiencing a car accident certainly qualifies as a catastrophic event.

Fight or Flight

The term “fight or flight,” is often associated with circumstances under which adrenaline is released into the body.

The fight or flight response is a built-in mechanism dates back to our early ancestors allowing them to cope better with dangerous and unexpected situations.

With dilated blood vessels and air passages, the body can pass more blood to the muscles and increase oxygen in the lungs in a prompt manner, resulting in a boost in physical performance for short bursts of time.   

For example, if we are attacked by a dog or involved in a severe auto accident.

We experience an energetic feeling that gives us the power and strength to either escape or attack. Because of this, an adrenaline rush can be intense and used to avoid danger or react quickly and even help rescue others.

Physical Side Effects From Adrenaline During a Car Accident

  • Your vision can become tunneled in a forward direction-often causing threats from the side to disappear from your field of vision  
  • Your hearing can also become tunneled-sometimes preventing you from hearing attacks or warnings that come from the side
  • No feelings of pain
  • Heightened sense
  • Sudden boost of energy
  • Increased breathing
  • Dilated blood vessels
  • Increased blood flow

After-Effects of Adrenaline Surge

  • Your hands can shake making you feel quite weak. This is because of the falling blood sugar that was pumped into your system to provide the energy needed for a flight-or-fight survival response
  • Sometimes with a sudden loss of adrenaline and endorphin rush can result in sudden fainting. This sudden fainting episode is caused by a drop in blood pressure and heart-rate, and should not be confused with the fear response.
  • The unexpected release of intense emotion that was suppressed during the adrenaline surge, most often this erupts in the form of crying.

What Is Adrenaline?

Adrenaline is a natural hormone that is produced by the adrenal glands and secreted throughout the body when we undergo some traumatic experience.

An Adrenaline Rush is an incredibly intense feeling such as sadness, happiness, or any other intense emotion.

The purpose of this hormone is to create a powerful natural reaction designed to give our bodies the strength to escape or attack a dangerous threat.

What Are Endorphins?

Endorphins are neurotransmitters in the brain and act as natural pain relievers.

Neurotransmitters are the chemicals which allow transmission of signals from one neuron to the next across synapses.

These chemicals transmit signals throughout the nervous system and are found in the part of the  brain specifically in the pituitary gland.

A receptor is a molecule that transmits signals, and an endorphin binds to a receptor that morphine and other opiates gravitate to, known as “opioid receptor.”

Endorphins affect both emotional responses and blocking pain. When endorphins interact with the opioid receptors, pleasure and satisfaction are experienced.

The pituitary gland and the hypothalamus in vertebrates produce endorphins during:

  • Exercise (runners high)
  • Excitement
  • Pain
  • Spicy food consumption
  • Love
  • Sexual activity

The reproduction of endorphins requires positive stress such as, diet, exercise, and general well-being, but stress and pain trigger their release as well.

The Psychological Model

Glad, sad, and mad, with fear as a sidebar. In general, a person is typically in glad mode.

If stress weakens a persons’ state to sad or mad, endorphins are released for re-elevating them to glad.

If fear is ignited, endorphins similarly allow coping by providing a feeling of calm euphoria. Therefore, our brain maintains a certain quota of endorphins to ensure survival under duress.  

Most car accidents will create a similarly heightened level of excitement.

Your body will generate endorphins and adrenaline, which means you feel increased energy possibly a lack of pain. 

The same concept happens with athletes who are injured during a game, and they continue to play without noticing the injury until the game is over.

That's because their bodies are producing adrenaline and endorphins, these two chemicals super-charge our bodies and even block pain.
