On Halloween, the biology of fear, and our capacity to meet the unknown
My fifteen-year-old daughter recently showed me a clip from a horror movie her friends watched at a sleepover. Apparently, voluntarily terrifying yourself in the company of friends is a perfectly reasonable way to spend a Saturday night.
I told her I didn’t particularly need to watch something that made my heart race. I could accomplish that quite easily by running through the cemetery near our house.
Although, to be fair, the cemetery is one of my favorite places to run. It’s quiet, the views are beautiful, my dog and I don’t have to worry about traffic, and there’s a certain freedom in moving through a place where no one is in much of a hurry.
I don’t find it very frightening. But it got me thinking. Why do we deliberately seek experiences that frighten us? Horror movies, extreme sports, haunted houses. Why would a species whose nervous system evolved to protect it from danger voluntarily manufacture experiences that resemble it?
And perhaps more curiously, why do we sometimes seek fear for entertainment while becoming increasingly uncomfortable with uncertainty in our everyday lives?
When Fear Becomes Something Else
Fear is one of our oldest biological protections. When the brain perceives a threat, neural networks coordinate a response throughout the body. Heart rate increases, breathing changes, attention sharpens, and muscles prepare for action.
These are not signs of a malfunctioning nervous system. They are evidence of its remarkable capacity to respond.
Interestingly, research into recreational fear suggests that we enjoy a certain degree of this activation. Too little fear is boring. Too much becomes overwhelming. Somewhere in between, we find exhilaration.
But there’s an important distinction between fear and anxiety.
Fear generally responds to something happening now. Anxiety anticipates what might happen next.
And our remarkable human capacity to imagine the future means we can experience genuine physiological responses to events that haven’t occurred, and may never occur.
Modern life offers no shortage of possibilities to worry about. Health risks, economic uncertainty, social expectations, global events, and an endless stream of information about everything that might go wrong.
We can watch terrifying movies, follow disasters, and witness extraordinary human challenges from the safety of our screens. We experience some of the activation without having to participate in the event.
There’s nothing inherently harmful about this. Recreational fear can be enjoyable, and witnessing challenges can be inspiring. But repeated attention to threatening information that feels beyond our control can contribute to anticipatory stress.
I wonder whether our increasing ability to identify and imagine danger has sometimes outpaced our confidence in our capacity to navigate it.
The Difference Between Fear and Excitement
When I coached girls basketball, I often inquired about knowing the difference between fear and excitement.
Imagine standing at the free-throw line with the game tied and only seconds remaining.
Your heart is pounding. Your breathing changes. Everyone is watching.
Are you afraid? Or are you excited?
Physiologically, these experiences share many features. What changes is how we interpret the activation.
What if I miss? What if I let everyone down?
Or:
Here’s my opportunity. I’ve practiced this. I’m ready to take the shot.
I would encourage the kids to take a breath, feel their feet, and return their attention to the task.
Not because breathing magically eliminates fear, but because it offers a moment to recognize the experience without becoming consumed by it.
In yoga, Prāṇāyāma explores the relationship between breath, attention, and prāṇa. Modern physiology offers complementary explanations for how breathing influences autonomic activity and attentional regulation.
My Vaidya describes a kind of double-arrowed attention: awareness directed both inward and outward.
The athlete remains aware of the breath, the body, and the experience of readiness while simultaneously engaging with the basket, the movement, and the task at hand.
There is a calm within the tension.
The goal isn’t to eliminate the racing heart. It’s to remain present and capable of executing a practiced skill.
The lesson reaches beyond whether the shot goes in. It’s the experience of trusting your preparation, meeting the moment, and discovering what you’re capable of.
A Different Relationship With Healthcare
This distinction becomes particularly interesting in medicine.
Modern healthcare has developed extraordinary tools for identifying pathology and predicting disease. We can recognize metabolic risk, cardiovascular patterns, and early physiological changes long before symptoms become significant.
These capabilities are essential. But risk is not the same thing as danger, and identifying the possibility of disease is not the same as understanding the conditions that contribute to health.
A concerning laboratory result can become more than clinical information. It can become a story about an uncertain future. Without context, that story may generate fear, hypervigilance, or a sense that the body is increasingly unreliable.
I wonder whether our increasing focus on identifying what might go wrong sometimes diminishes our confidence in our capacity to influence what happens next.
Integrative Ayurvedic Medicine (IAM) offers a broader way to engage with this information.
Rather than focusing exclusively on pathology or waiting for diagnostic thresholds, we examine the patterns and conditions shaping an individual’s physiology.
How are sleep, circadian rhythms, nutrition, movement, stress, relationships, environment, and individual constitution interacting?
What is the body adapting to? Where is it compensating? What conditions might support greater capacity?
This approach doesn’t replace diagnosis or evidence-based treatment. It adds context and helps us understand the relationships contributing to the current state of health.
Risk identifies a possibility. Patterns help us understand the present. Capacity gives us something to cultivate.
In Ayurveda, Dhṛti refers to restraint, resolve, and the capacity to sustain appropriate direction. I find it a useful concept for understanding how we participate in health: not by controlling every outcome, but by developing the awareness and steadiness to respond appropriately to changing circumstances.
The patient becomes an active participant in understanding and influencing the conditions of their health, rather than simply waiting for pathology to develop or trying to prevent every possible outcome.
Perhaps preventive healthcare should concern itself not only with what might go wrong, but with understanding what allows health to emerge and remain adaptable.
The Calm Within the Tension
Perhaps fear isn’t always telling us something is wrong.
Sometimes it tells us something matters. Sometimes it protects us. Sometimes it reflects an unfamiliar experience or a future we’ve imagined but haven’t yet encountered.
The goal isn’t to eliminate fear or uncertainty from our lives, but to develop the discernment to recognize when fear deserves our attention and when we can remain present despite it.
We don’t all need to climb mountains or jump from airplanes to discover our capacities.
Sometimes the challenge is standing at the free-throw line. Sometimes it’s receiving unexpected health information, having a difficult conversation, or making a decision without knowing the outcome.
Perhaps vitality isn’t found in the elimination of tension, but in our capacity to remain appropriately engaged with life while tension exists.
As for me, I’ll keep running through the cemetery.
The views are lovely, the company is quiet, and my dog seems entirely unconcerned about the ghosts.
Happy Halloween.
