Psychology Explains the Causes of Nyctophobia (fear of the dark)



Remember when you were at summer camp as a kid, and everyone asked each other if they were afraid of the dark? Fear of darkness is probably one of the main primordial concerns that are hardwired into our brain. Before early humans discovered fire, the night was a fearful place of danger lurking in every shadow.

Being afraid of the dark is a common fear in childhood. They are fearful of the make-believe monsters under the bed and things that go bump in the night. Fortunately, most people outgrow this fear and think nothing of sleeping in a darkened room.

For some people, being afraid of darkness carries on into adulthood. They may understand that there’s nothing to fear at night or when they enter a darkened room, yet they still have this irrational concern. When worry is irrational and starts to impede a person’s daily living, it becomes a phobia.


Phobia comes from the Greek word for fear. However, comparing fear to a phobia is like comparing a house cat to a lion. Mental health experts consider phobias an anxiety disorder. For the person with this extreme anxiety, the fear and threat are real, no matter how unfounded the reason.

What is Nyctophobia?

Nyctophobia, also known as lygophobia, is the irrational fear of darkness and dark places. While many adults may still be afraid of the dark, some people may have had their fear morph into a phobia. Nyctophobics experience extreme anxiety at night or in dark places.

They will actively avoid going into dark rooms and may carry a flashlight wherever they go. It’s usual for those with nyctophobia to sleep with the lights on and become anxious when the day turns to night. They often will not go to theaters or participate in anything to do with a darkened room.




What are the Signs & Symptoms of Nyctophobia?

Although this anxiety disorder may be one of the easiest to treat, some people may hesitate because it makes them look silly or weak, especially men. However, if nyctophobia is left untreated, it can wreak havoc on people’s lifestyles, work, and relationships. The signs and symptoms of this phobia are easy to recognize.


  • Hyperventilation or feeling like you can’t breathe
  • Dry mouth
  • Heart palpitations or a rapid heartbeat
  • Numbness in limbs or entire body
  • Dizziness
  • Heightened senses/awareness
  • Tensed Muscles
  • Nervous trembling
  • Intense fear of impending danger or disaster
  • Feeling out of control or thinking that you are dying
  • Feeling trapped and can’t escape

If you’ve ever been diagnosed with a panic disorder, you will probably recognize many of these same symptoms of a panic attack. If you are nyctophobic, it is nighttime or a darkened room that triggers these symptoms. They can be severe enough to cause sleep deprivation and other mental disorders.

Talk to your primary healthcare provider if you notice any of these symptoms. Because these may mirror other ailments, you must be diagnosed by a professional to rule them out. The proper diagnosis can make it easier for your healthcare provider to formulate a treatment plan that’s best for you.

Four Typical Causes of Nyctophobia

One reason that this anxiety disorder can flourish is that it builds on primary childhood fears. Sometimes, certain medical conditions or trauma can exacerbate fear of the dark and turn it into a gripping phobia. Although each case may vary, these are some of the reasons some people develop into a nyctophobic.

1 – Learned Fear

As parents and guardians, you are a role model for your children. They learn at an early age to model your emotions by how you react to things. It’s not uncommon for a nyctophobic parent to pass on the phobia as a learned behavior.

Some studies suggest that phobias, in general, may run in families genetically. However, experts are quick to point out that environmental causes can also be the culprit. No one really knows where nurturing ends and nature begins when it comes to anxiety disorders.

2 – Childhood Abuse at Night

Even in the 21st century, childhood abuse and exploitation are alive and well. Nearly 3 million cases of child abuse and neglect are reported every year in the United States. Sadly, experts believe that many more cases go unreported, and as many as five children die from their abuse each day.


Physical, verbal, emotional, and sexual abuse are enough to give any child a lifetime of night terrors. Often, parents who are substance abusers become violent in the night because they are out of drugs or alcohol or are coming off a high. In the shadows of the night, when children should be sleeping warm and safe in their beds, sexual predators such as perverse relatives or deviant boyfriends often seek their victims.

If you’ve been a survivor of child abuse, you know that nighttime can trigger unspeakable memories that put your panic into overdrive. When the lights go out, you may relive each scene in a painful loop. Childhood trauma can be a tremendous factor in causing nyctophobic reactions.

3  –  Childhood trauma

Some traumatic events in childhood have nothing to do with child abuse or neglect. These can happen in the most loving and nurturing homes. The death of a loved one is often painful for children to process, and it can often disrupt their sleeping patterns. Serious accidents and illnesses can also have a negative effect on children’s minds, and it causes them to react to darkness with fear.

If left untreated, it’s easy for this nocturnal fear to turn into a phobia. If you had a traumatic event in your life that disrupts your sleep and showers you with anxiety, consider talking to your mental health professional about nighttime phobias.

4 –  Other Mental Illnesses

It’s also possible that other phobias and mental disorders can play into lygophobia. Those who have phobias of being alone or separation anxiety may develop a phobia of the dark. Since the symptoms of so many mental disorders overlap, it’s imperative to seek the counsel of an experienced mental health professional for a diagnosis.
