Our topic for today is the role of fear and how it shapes our lives. Our goal is to enhance our understanding so that in part two of this article, we can learn how to manage it effectively and harness its potential for our benefit.

We all know change can be unsettling, and the fear factor is real. It is a natural response to feel anxious when our typical routines are disturbed. It’s also natural to be scared to try new things, even if they could be helpful. We’ve all been there – that moment when our heart races, our palms get sweaty, and our mind goes into overdrive.

Fear is something we all go through. We instinctively recognize the symptoms of the state of fear. We understand the emotions, physical sensations, and mental limitations. Fear can be a helpful instinct that keeps us safe in certain circumstances. It’s helpful when we have a good relationship with it.

But it can also trap us and keep us from moving forward. Fear can warp our view of the world. Why is that? Let’s dive into the world of fear and explore what makes up the mind’s alarm system.

Nature Of Fear:

What is fear? Basically, it is our bodily process that gets triggered when we perceive a threat. It is our brain’s way of saying, “Hey, watch out!” So what exactly is considered a threat?

Threat

A threat is a person, place, or thing that we see as harmful. It can be anything – from physical danger to financial trouble or even social embarrassment. Threats may arise from natural disasters, technological failures, or malicious activities like cyberattacks or terrorism. Interpersonal threats that may come up include communication problems, abuse, friends breaking confidences, or team members making poor decisions that result in big losses.

The fear cycle starts when we encounter a triggering stimulus or threat, and it ends with the release of chemicals in our bodies that increase heart rate, energize muscles, and cause rapid, shallow breathing. This physiological effect prepares us to react to the threat. The key to successful outcomes when we are triggered by a threat all comes down to how we respond to the threat. Successful outcomes base this response by distinguishing if the perceived threat is valid or irrational.

Response

Distinguishing between a valid and an irrational threat is a critical skill for managing our response to fear effectively. Objective assessment and rational thinking are crucial in distinguishing between the two. When we encounter a potentially threatening situation, we need to pause and carefully evaluate the evidence, consider the likelihood and potential impact of the threat, and seek reliable information to determine if our fear is justified.

Let’s get into the nitty-gritty of valid versus irrational threats.

Valid Threat=  there is solid evidence and a realistic chance of it happening. When faced with threats, it is crucial to respond thoughtfully, as valid threats can pose a genuine risk to our safety, well-being, and important aspects of our lives. For instance, if there’s a legitimate weather warning about an approaching hurricane, it’s a valid threat that requires appropriate precautions.

Irrational Threat= usually have little to no evidence supporting them or are highly unlikely to happen. A prime example of an irrational threat is when someone has an extreme fear of flying, despite overwhelming evidence that it is one of the safest ways to travel.

Now, let’s look at some real-life examples to better understand the difference.

Valid Threat: Your coworker consistently takes credit for your work and ideas during team meetings. This behavior poses a real threat to your professional growth and recognition within the company. In this case, it’s reasonable to feel concerned and take action, such as documenting your contributions or addressing the issue with your supervisor.

Irrational Threat: You are invited to attend a party, but the anxiety you experience is overwhelming because you’re convinced that everyone will judge you negatively. Even though there’s no proof and you’ve had fun before, you let this fear take over.

Valid Threat: You notice that your romantic partner has become secretive with their phone, works late frequently without explanation, and seems emotionally distant. These behavioral changes could indicate a potential threat to the relationship, such as infidelity or growing apart. It’s totally normal to feel concerned and seek having an honest conversation about where you both stand.

Irrational Threat: You become paranoid and jealous every time your partner talks to someone of who is attractive, despite having no evidence of inappropriate behavior. This irrational fear can strain the relationship and create unnecessary drama.

When we can tell the difference between real and irrational threats, we can respond more effectively in different situations. When confronted with a legitimate threat, we can implement well-thought-out and efficient strategies to defend ourselves or lessen the risk involved. On the other hand, acknowledging an irrational threat lets us confront our baseless fears, get help if necessary, and stay away from unnecessary stress and anxiety.

Developing this skill is really worth it. It improves our decision-making skills by letting us focus on real challenges, not imaginary ones. It also makes us less stressed and improves our mental well-being in all areas of life. By being smart about potential dangers, we can handle personal and professional situations with more confidence and clarity.

Anatomy Of Fear

We now have learned that fear is a physiological response to a stimulus/threat. But how does our brain decide how we react when there’s a threat? Our brain’s structures and wired pathways control how we react to fear. It’s a good idea to grasp how the brain handles fear, so we can see how our body responds to danger.

The Brain:

Our brain is like a complex control center, with different areas handling various tasks. Three basic units of the brain are the forebrain, midbrain, and hindbrain. Each of these units contains lobes: frontal, parietal, temporal, and occipital. If you are interested in the brain structure, you can learn more.

For our fear discussion, let’s focus on two key players: the frontal and temporal lobes.

Frontal Lobe

This is where Higher Cognitive Functions occur. This is where our “adulting” happens – thinking, problem-solving, and self-awareness. These advanced mental processes are the hallmarks of human intelligence and maturity. Here’s what this area helps us do:

• Make informed decisions through complex reasoning and analysis.
• Enable us to plan, set goals, and strategize.
• Promote personal growth and emotional intelligence through self-reflection.
• Explore ethics, philosophy, and develop our worldviews.
• Fuels our creativity and innovation.
• Super important for how we interact with others, helping us understand their point of view, handle tricky relationships, and make a real impact on society.

As we enhance our cognitive abilities in this brain region, we become better at handling challenges, making judgments, and growing as individuals. This area of the brain helps us determine if a threat is real.

The Temporal Lobe

The temporal lobe is like the memory master. It has a significant role in processing visuals and sounds, and it is essential for recognizing objects and understanding language. This area is where the limbic system hangs out.

The limbic system controls emotions, motivation, memory, and safety. This area of the brain helps us determine if a threat exists.

Inside the limbic system, there is a part called the amygdala. When we stumble upon something scary, our limbic system says, “Hey amygdala, tell the rest of the brain to get ready to fight, run, or freeze.”

The amygdala acts as our brain’s threat detector, categorizing incoming information as either “threat” or “non-threat.” But how does this external data reach the amygdala?

The answer lies in our neural network. Billions of nerve cells, called neurons, facilitate this information transfer. These microscopic messengers gather data from our environment through our five senses – sight, hearing, taste, touch, and smell. They then relay this information using the central nervous system as their superhighway. This intricate system ensures that our brain, particularly the amygdala, receives a constant stream of sensory input, allowing us to rapidly assess potential threats in our environment.

Central Nervous System

Alright, let’s dive into this superhighway called the Central Nervous System and its two operating states. One state is all about peace and relaxation, while the other is all about emergency response system.

Our nervous system has two modes:

The Sympathetic: The “Oh no!” mode (fight, flight, or freeze). This gives us the energy and acute mental focus to handle the threat.

The Parasympathetic: The “Chill out” mode (rest and digest). Our heart rate is normal and we’re breathing calmly. Typically, we think clearly and use the higher cognitive functions of the Frontal Lobe effectively.

The sympathetic system gets us ready to go, while the parasympathetic system brings us back to normal. These two systems work hand in hand, constantly changing our body to fit our needs. Knowing how these systems interact can help us understand how our bodies react to stress and relaxation, so we can take better care of ourselves.

So how do nerves cells (neurons) communicate with each other?

Neurotransmitters

So, there are these things called neurotransmitters that neurons use to chat with each other in our nervous system. These special molecules help signals travel between neurons, so information flows smoothly through the body.

Neurotransmitters are involved in virtually all functions of the body, including:

• Regulating mood (e.g., serotonin, dopamine)
• Controlling movement (e.g., acetylcholine)
• Managing sleep cycles (e.g., melatonin)
• Modulating pain (e.g., endorphins)
• Regulating appetite (e.g., ghrelin, leptin)
• Influencing learning and memory (e.g., glutamate)

Two crucial neurotransmitters that are involved when a threat is present are epinephrine and norepinephrine.

Epinephrine, also known as adrenaline, and norepinephrine, aka noradrenaline, are chemical messengers, as well as hormones, that help nerves, muscles, and glands talk to each other. They tell our bodies to open up and take in more oxygen, speed up our heart rate and blood flow for an energy boost, and slow down digestion. These messengers help the sympathetic nervous system get us out of danger.

However, when the body becomes accustomed to frequent adrenal surges caused by repeated exposure to danger, it throws the system out of balance. Various neurological and psychiatric conditions are linked to imbalances in neurotransmitter levels or function. That’s why many medications focus on targeting neurotransmitter systems to treat these disorders.

Long-Term Effects

Staying in “Oh no!” sympathetic mode for too long can mess with our entire system. We’re not functioning as well as we were meant to. Fear disrupts the balance of our body, moods, mind, and spirit. Here are some known consequences:

Physical Disruptions:

• Immune system dysfunction
• Organ dysfunction
• Endocrine system dysfunction
• Metabolic system disruption
• Sleep/wake cycle disruption
• Hypertension, which increases the risk of heart attacks, strokes, and kidney disease.

Mood Disruptions:

• Depression
• Intense mood swings
• Dissociation from self

Mental Disruptions:

• Cognitive decline, particularly affecting memory
• Anxiety dysfunction
• Poor rational decision making
• Poor impulse control

Spiritual Disruptions:

• Sense of loss of trust/faith
• Loss of inner joy and peace
• Overall sense of separation and loneliness.
