It is a fundamental, deeply wired reaction, evolved over the history of biology, to protect organisms against perceived threat to their integrity or existence. Fear may be as simple as a cringe of an antenna in a snail that is touched, or as complex as existential anxiety in a human.

So, it makes sense that the high arousal state we experience during a scare may also be experienced in a more positive light. We are psychiatrists who treat fear and study its neurobiology. Our studies and clinical interactions, as well as those of others, suggest that a major factor in how we experience fear has to do with the context. When you enter a haunted house during Halloween season, for example, anticipating a ghoul jumping out at you and knowing it isn’t really a threat, you are able to quickly relabel the experience. In contrast, if you were walking in a dark alley at night and a stranger began chasing you, both your emotional and thinking areas of the brain would be in agreement that the situation is dangerous, and it’s time to flee! But how does your brain do this? Fear reaction starts in the brain and spreads through the body to make adjustments for the best defense, or flight reaction. The fear response starts in a region of the brain called the amygdala. For example, the amygdala activates whenever we see a human face with an emotion. This reaction is more pronounced with anger and fear.

A threat stimulus, such as the sight of a predator, triggers a fear response in the amygdala, which activates areas involved in preparation for motor functions involved in fight or flight. It also triggers release of stress hormones and sympathetic nervous system. This leads to bodily changes that prepare us to be more efficient in a danger: The brain becomes hyperalert, pupils dilate, the bronchi dilate and breathing accelerates. Heart rate and blood pressure rise. Blood flow and stream of glucose to the skeletal muscles increase. Organs not vital in survival such as the gastrointestinal system slow down. A part of the brain called the hippocampus is closely connected with the amygdala. The hippocampus and prefrontal cortex help the brain interpret the perceived threat. They are involved in a higher-level processing of context, which helps a person know whether a perceived threat is real.

For instance, seeing a lion in the wild can trigger a strong fear reaction, but the response to a view of the same lion at a zoo is more of curiosity and thinking that the lion is cute. This is because the hippocampus and the frontal cortex process contextual information, and inhibitory pathways dampen the amygdala fear response and its downstream results. How do we learn the difference? Similar to other animals, we very often learn fear through personal experiences, such as being attacked by an aggressive dog, or observing other humans being attacked by an aggressive dog. If a sign says the dog is dangerous, proximity to the dog will trigger a fear response. We learn safety in a similar fashion: experiencing a domesticated dog, observing other people safely interact with that dog or reading a sign that the dog is friendly. Why do some people enjoy being scared? Fear creates distraction, which can be a positive experience. Furthermore, when we experience these frightening things with the people in our lives, we often find that emotions can be contagious in a positive way. We are social creatures, able to learn from one another.

So, when you look over to your friend at the haunted house and she’s quickly gone from screaming to laughing, socially you’re able to pick up on her emotional state, which can positively influence your own. While each of these factors – context, distraction, social learning – have potential to influence the way we experience fear, a common theme that connects all of them is our sense of control. When we are able to recognize what is and isn’t a real threat, relabel an experience and enjoy the thrill of that moment, we are ultimately at a place where we feel in control. That perception of control is vital to how we experience and respond to fear. It is important to keep in mind that everyone is different, with a unique sense of what we find scary or enjoyable. This raises yet another question: While many can enjoy a good fright, why might others downright hate it? Why do some people not enjoy being scared? Any imbalance between excitement caused by fear in the animal brain and the sense of control in the contextual human brain may cause too much, or not enough, excitement.
