Selenophobia Symptoms, Causes and Treatment

Selenophobia is a feeling of irrational fear or dread of the moon, the evening and its light. All the symptoms suffered by people with this phobia are intensified if they are under a full moon.

The problem can be so severe that affected people, in addition to being afraid to observe it on any evening, are repulsed by the word “moon” or simply by images of it.

To understand what selenophobia is, I will begin with a brief description of the concept of the phobia. Derived from the word Phobos, which means panic. It is an intense and irrational fear of a pathological nature about a person, thing or situation. Phobia is much more serious than simple fear. Those who suffer from it have an overwhelming need to refrain from anything that might cause them anxiety.

Selenophobia is within what are called specific phobias. They are considered a type of anxiety disorder in which a person may experience extreme symptoms of anxiety or experience a panic attack when exposed to an object that causes irrational fear.

Fear of the Moon or Moonlight Phobia

In a person with selenophobia, the simple fact of having to go out at night and face an object that causes discomfort (in our case, the moon) can cause severe physical and psychological feelings of anxiety and panic.

Selenophobia refers to a specific phobia in the type of environment where the fear refers to situations related to nature and atmospheric phenomena such as rain, storms, precipices or water.


Causes of specific phobias, such as selenophobia or moon phobia, usually develop when the child is four to eight years old. In some cases, they may be the result of some traumatic event developed at an early age that caused the phobia.

Also, fear of a relative is a common cause of it in childhood because they learn through vicarious learning…

In the case of selenophobia, the causes that may have caused it are actually unknown. It is not clear whether it is due to some past event or to mediocre learning, although it is true that phobias of the type of environment, of which selenophobia is among them, usually develop in childhood.

Phobias that persist through adulthood rarely go away (only in 20% of cases).

Perhaps the reasons can be oriented to this, usually when we think of the moon, we usually think of its greatness and therefore how great some of the natural phenomena occurring on Earth are. It makes us think about how little people feel in front of it all. This, in a way, may explain this phobia.

To diagnose specific phobias, we have to consider the different diagnostic criteria outlined by the DSM:

  • An accused and persistent fear that is excessive or irrational, triggered by the presence or expectation of a particular object or situation, in this case the moon.
  • Exposure to the moon almost spontaneously triggers an anxiety response. Keep in mind that anxiety in children usually manifests as tantrums, crying, inhibition, or hugging.
  • The person admits that the fear of the moon is excessive or irrational. In children, this recognition cannot be presented.
  • Avoids encountering the moon or, if encountered, is maintained with great anxiety or discomfort.
  • Lunar avoidance behavior, preemptive anxiety or discomfort caused by the feared situation, interferes in a way that disrupts the individual’s normal rhythm of life, work, social and family relationships. In addition to the clinical symptoms from which the person suffers.
  • If the phobia has occurred in children under the age of 18, the duration of the symptoms must be a minimum of 6 months.

The health care provider, before diagnosing someone with a phobia, must carefully evaluate the patient by checking their medical history and performing a complete physical examination. In addition, various psychological tests will be performed to rule out another pathology both physically and psychologically. All this in order to rule out that the symptoms presented are related to another disorder.

Selonephobia can ruin and destruct life

The therapist should always make sure that the symptoms of anxious, distressing or avoidant behavior in relation to the moon are not caused by the presence of another mental disorder (OCD, post-traumatic stress disorder, separation anxiety disorder.) , social phobia, agoraphobia or agoraphobia disorders without a history of agoraphobia disorder).

If the family doctor suspects or believes the patient has a phobia and it is serious enough to affect the normal functioning of his life, he should refer him to a psychiatrist or psychologist. The medical professional, using various methods and assessment tools, such as psychological tests, will be able to assess the patient’s current situation and, if necessary, initiate follow-up treatment.

Consequences of a phobia

To give you a better understanding of the effects a phobia can have on the person suffering from it, I will go on to describe what is going on in the body:

  • Increased autonomic activation: These reactions occur at the level of the physiological system. Some of the symptoms that may appear are tachycardia, sweating, hot flashes, pallor, upset stomach, dry mouth, diarrhea, etc. Д..
  • Motor system reactions in the form of avoidance or escape: when the subject is unexpectedly confronted with a situation to be feared, and if forced to remain in such a situation, then impaired motor activity at the vocal and/or verbal level may occur.
  • Reactions at the level of the cognitive system: These are reactions such as expecting both favorable and disastrous consequences. They occur compulsively. And actions occur at the obligatory level of escape or avoidance. On a physiological level, the amygdala is the one that is most important for storing and recovering the dangerous events from which we suffer. Located in the brain behind the pituitary gland, it triggers the release of “fight or flight” hormones to confront vigilance or high stress situations. Thus, when an event similar to the one that occurred earlier occurs in the future, this area reconstructs from its memory the actions previously performed, and the body reacts as if it had happened the same way it did the last time. The person can experience it as if it were returning to the first place, with the same symptoms.

It should also be noted that large changes in a particular phobia, as in the case of selenophobia, can cause a person to leave only the nights of the new moon (when the moon is not valued). This greatly disrupts his normal life, especially limiting him in his social or work life, preventing him from performing night work.


Selenophobia requires treatment or therapeutic support, for which there are various methods of treatment. In the following I will explain each of them:

  • Psychological Exposure TechniquesIn this technique, professionals confront the patient with a horrible situation, in this case the moon. Gradual and gradual exposure causes people to gradually control their fears, also reducing the symptoms caused by anxiety. A person affected by selenophobia can undergo a gradual exposure procedure, starting with trying to go out at night to the waning or rising moon without having to observe it, so that later in the last phase of the exhibition they can face the night of the full moon and be able to observe it directly.
  • Systematic Desensitization: This technique uses the patient’s imagination or gradual exposure to project a fearful stimulus into their mind instead of confronting life on the moon. In both treatment examples, exposure or imagining the stimulus stops when the patient cannot control his or her anxiety and resumes when anxiety levels decrease. Gradually the subject manages to resist for longer and longer periods, and thus the fear is lost.
  • Cognitive therapy: with this technique, we try to give the patient all the opposing information possible in order to cancel the beliefs the subject has about the situation or object he is afraid of. In this way you want to seek reassurance and gradually become familiar with it, aiming so that the person does not perceive this stimulus as something to be afraid of, and can go against the fact that his fear is irrational and exaggerated.
  • Strike methods: these are treatment methods that are within the behavioral approach, where there is a forced exposure to a stimulus until the subject’s anxiety has diminished and he or she can control it. It differs from systematic desensitization in that in this method the subject confronts the Moon directly, without any aggravation of the situation.
  • Neurolinguistic Programming: This is currently a treatment that is often used before certain phobias, but the results have not yet been scientifically proven.

Other alternative therapies include Bach color therapy, books and self-help groups, and hypnosis. The use of psychotropic medications is not usually recommended in the treatment of phobias because, although it may alleviate the symptoms of anxiety, it does not eliminate the problem. In any case, if anxiety symptoms need to be reduced, the most useful pharmacological treatments for this phobia are serotonin reuptake inhibitors.

Some treatments are able to make changes in the brain, replacing memory and pre-existing reactions with more adaptive behavior. Phobias are irrational phenomena; the brain reacts to a stimulus.
