Why we pay to be scared

Why so many people love roller coasters even though they’re scary

When a threat arises, it triggers our bodies to go into fight-or-flight mode and prepare for danger. However, when no obvious threat to our safety is present, this natural high can become enjoyable. Some people are more likely to enjoy these thrills based on factors like individual brain chemistry or physical health.

Researchers are studying roller coasters to improve mental health treatments

Scary rides stimulate our fight-or-flight response while simultaneously releasing feel-good endorphins like dopamine, serotonin, and oxytocin. Once we realize we're in a safe space, we can enjoy the ride and even feel confident and relieved by the accomplishment of overcoming a fearful feat.

Some people may be genetically predisposed to loving roller coasters

Recent studies indicate that individuals with higher levels of dopamine may be more prone to thrill-seeking behaviours like riding roller coasters or even doing drugs or shoplifting.

Why are humans hooked on horror?

A haunted horror attraction in Denmark is regularly stalked by researchers of the world's only laboratory dedicated to understanding fear's good side. Fear is one of many human emotions that correspond to a physiological response. As fear rises, so do adrenaline, cortisol, and heart and breath rates. As it ebbs, the body is flooded with dopamine, a hormone and neurotransmitter associated with desire, learning, and motivation.

The science of fear

The Hidden Brain podcast team explores the science of fear by traveling to a haunted house curated by a scientist to investigate what scares us, and why some people enjoy this sensation more than others.

Fearology, or the study of fear, explores the difference between stress and fear

Our brains involuntarily respond to our environment and signal alarm when that isn’t always needed, triggering responses that include goose bumps. But understanding fear and how to talk our brains into calming down can improve daily life.

Some theorize that horror's artifice turns fear into enjoyment

The “excitation transfer theory” suggests that the unpleasant feelings a jump scare might elicit (like shortness of breath) are quickly relieved when the audience member remembers what they’re witnessing is fake.

This video breaks down FOMO—what it is, how it works, and why it happens—showing how social comparison and uncertainty trigger anxiety that pushes people toward risk-taking and constant checking behaviors.

Roller coasters can cost millions of dollars to make, but they often offer a substantial payoff

Over 6,000 roller coasters are in operation around the world as of 2025, with ongoing demand to build more each year. Despite being costly (some theme parks pay upwards of $50M for these rides), their financiers are able to justify the investment when considering the long-term value of a ride that sticks around for decades with daily streams of visitors.

Why the human brain loves opioids

When opioids enter the brain, they dock in receptors, blocking electrical pulses such as those that communicate pain. They also trigger the release of dopamine, a neurotransmitter tied to motivation and associated with stress relief.

Music may give some of us the chills and goose bumps—perhaps because it shocks us

The science is still unsettled about why music can trigger a chill down your spine, formally known as frisson, but one theory is that anything surprising to the nervous system—including sudden beat drops or unexpected harmonies—stimulates a type of alarm response that gives rise to this feeling.

What exactly is dopamine?

Dopamine is a neurotransmitter—a chemical released by neurons that enables neural communication—that makes people want things with an "almost animalistic desire," compelling them to snack or check phone notifications. Often misrepresented as a "pleasure" chemical, dopamine is involved in motivation, learning, attention, habit formation, and more. Trends like dopamine fasting overinflate its role in mental health and often use it as part of "straw man" biohacking claims.

TikTok's personalized algorithm activates the brain's reward system

A 2025 Washington Post study found that 75% of the TikTok users it studied nearly doubled their time spent on the app within a month. Experts in design and psychiatry say this is due to the app's interface and algorithm, which, after learning about the user's preferences, recommend videos more likely to activate that person's dopamine reward system than non-personalized suggestions.

There are psychological benefits to believing in spirits

A number of psychologists believe religion helps subdue our fears of death by giving us a sense of what’s to come and, therefore, a sense of control over how to ensure the best possible outcome.

The myth of sugar rushes vs. the reality of sugar crashes

It's generally accepted that sugar rushes are a myth, and that hyperactivity is a more psychological experience. However, there is real science behind the rare sugar crash that primarily impacts those with diabetes.

NASCAR’s SAFER barriers help reduce tragedies at races

Following the death of Dale Earnhardt Sr. in 2001, NASCAR changed its culture to be safety-first. Part of its changes were to install barriers along tracks that would help absorb the majority of g-forces in a crash. This Daily Downforce article walks through the history of the SAFER barriers, why NASCAR originally chose concrete, and how much of the tracks are covered today.

What a railroad spike through the head taught science about the brain

In 1848, a railroad worker survived an accident that drove a 13-pound iron bar through his head. The injury changed his personality, and our understanding of the brain.
