According to Child and Adolescent Mental Health, approximately 5 percent of children suffer from specific phobias and 15 percent seek treatment for anxiety-related problems. In recent years the number of children with clinically diagnosed phobias has gradually increased. Researchers are finding that the majority of these diagnoses come anxiety related phobias or society phobias.

Specific phobias are more prevalent in girls than in boys. Likewise, specific phobias are also more prevalent in older children than younger.

Though some fears are inborn, the majority are learned. Phobias develop through negative experiences and through observation. One way children begin to develop fears is by witnessing or hearing about dangers. Ollendick proposes while some phobias may originate from a single traumatizing experience, others may be caused by simpler, or less dramatic, origins such as observing another child’s phobic reaction or through the exposure to media that introduces phobias.

- 2% of parents linked their child’s phobia to a [direct conditioning episode]

- 26% of parents linked their child’s phobia to a [vicarious conditioning episodes]

- 56% of parents linked their child’s phobia to their child’s very first contact with water

- 16% of parents could not directly link their child’s phobia

In addition to asking about the origins of a child’s fear, the questionnaire asked if parents believed that “information associated with adverse consequences was the most influential factor in the development of their child’s phobia.” The results were as followed:

- 0% of parents though it was the most influential factor

- 14% of parents though it was somewhat influential

- 86% of parents though it had little to no influence

Most people suffer from a form of fear of medical procedures during their life. There are many different aspects of this fear and not everyone has every part. Some of these parts include fear of surgery, fear of dental work and fear of doctors (involving fear of needles). These fears are often overlooked, but when a patient has one to the extreme it can be very damaging to their health.

Formally, medical fear is defined (by Steward and Steward, see Further reading) as "any experience that involves medical personnel or

procedures involved in the process of evaluating or modifying health status in traditional health care settings".

Fear of medical procedures can be classified under a broader category of “Blood, Injection, and Injury Phobias”. This is one of five subtypes that classify specific phobias. A specific phobia is defined as a “marked and persistent fear that is excessive or unreasonable, cued by the presence (or anticipation) of a specific object or situation.” Often these fears begin to appear in childhood, around the age of 5 to 9. It seems to be a natural feeling to become squeamish at the sight of blood, injury or gross deformity, but many overcome these fears by the time they reach adulthood. Those who do not are more likely to avoid medical and dental procedures necessary to maintain health, jobs, etc. Research shows that when people encounter something that they have a specific phobia of many of them have a feeling of disgust which makes them not want to come near or experience that which is disgusting to them. This feeling of disgust, especially in the Blood, Injection, and Injury Phobias seems to be passed down in families. Women have been known to avoid becoming pregnant because it requires blood and medical examinations that they would rather avoid. Also, most phobic people have an increased heart rate upon encountering the thing they fear, but Blood, Injection, Injury phobic people also seem to have an increase of fainting after the initial speeding up of heart rate. Their heart rate will go up and then slow again, leading to nausea, sweating, pallor and fainting. This fainting can also lead to seizures, making life very difficult for those who have this fear. However, only 4.5% of individuals who have this phobia as a child will have this fear their entire lifetime.

For those who do experience this phobia in an extreme manner, specific coping treatments have been found to help them. Biological treatments, like medications used for other anxiety ailments, are generally found to be inappropriate for fear of medical procedures or other specific phobias. Psychological treatments are the treatment of choice because they are more accurate at addressing the problem. Some of these treatments used especially for fear of medical procedures include, Exposure-Based Treatments, Eye Movement Desensitization and Reprocessing, and Applied Tension to react against fainting.

Digital phobic is an informal phrase used to describe a reluctance to become fully immersed in the digital age for being fearful of how it might negatively change or alter everyday life.

The fast-paced development of the digital world in the twenty-first century has contributed to the digital divide becoming a very real problem for a segment of the population for whom a lack of education of, interest in, or access to digital devices has left them excluded from the technological world and fearful of its growing omnipresence.

Digital phobic is part of a growing dictionary of digital vocabulary exploring the social impact of the technological age. The phrase considers the fears associated with technological evolution and change, and acknowledges the possibility of exclusion as a result of a rising reliance on technology in day-to-day life.

The alternative view is that the dangers, such as from spiders, are overrated and not sufficient to influence evolution. Instead, inheriting phobias would have restrictive and debilitating effects upon survival, rather than being an aid. For some communities such as in Papua New Guinea, Cambodia and South America (except Chile, Colombia, Brazil, Uruguay, Argentina and Bolivia), spiders are included in traditional foods. This suggests arachnophobia may be a cultural, rather than genetic trait.

Cyberphobia is a concept introduced in 1980, described as a specific phobia expressed as "an irrational fear of or aversion to computers" or more generally, a fear and/or inability to learn about new technologies.

Some forms of cyberphobia may range from the more passive forms of technophobia of those who are indifferent toward cyberspace to the responses of those who see digital technology as a medium of intrusive surveillance; more extreme responses may involve anti-technological paranoia expressed by social movements that radically oppose ‘technological society’ and ‘the New World Order’.

There are different ways that someone could experience cyberphobia. Teachers may experience a form of cyberphobia if they are forced to change their way of teaching. Another way people may experience cyberphobia is if they feel that they are incompetent, or that the new technology is not needed to advance in life, or that they feel that they lack skills for the new age of technology. Another way people may experience cyberphobia is if they feel like they are going to lose control, or the new technology will affect their status in life.

In China, frigophobia is known as Wei Han Zheng (畏寒症). From the standpoint of traditional Chinese beliefs, the disorder is highly influenced by an imbalance of yin (the female element) and yang (the male element). Chinese traditional beliefs also states that working women are particularly susceptible to frigophobia, triggered by a combination of stress, menopause, pregnancy and other disorders such as anemia. During winter, these women are likely to experience coldness in extremities and back pains caused by the disorder.

It is believed that the disorder can be treated using a combination of diet in order to re-balance the yin and yang. A common dietary treatment include:

- Chicken soup

- Turnip juice mixed with ginger juice and honey, three times a day

- Red tea with ginger juice and sugar, two times a day

- Foods containing yeast (e.g. bread)

- Spices (ginger, chili pepper)

- Vinegar diluted in water

It is also believed that the dietary treatment will be more effective if taken in conjunction with an acupuncture routine.

A case study of a 45-year-old Singaporean housewife with frigophobia was studied and the results concluded: frigophobia is closely related to, and strongly influenced by cultural beliefs. Generally speaking, in therapy, treatments would consist of using low dose of anxiolytics and antidepressants, and psychological interventions. But usually when Asian women are notified of the illness, they would adopt various measures to recover. These include withdrawal from workforce, avoid exposure to cold air and wind, and most importantly they will take dietary precautions. It would be rather important to consider the patient’s cultural beliefs about the “illness” in comparison to the therapist’s belief of the illness, and then find a negotiable approach for the treatment.

Research shows that opposition to attitudinal change can gradually give way to acceptance with the passage of time. Attitudinal change towards acceptance may be a slow and even tedious experience for some teachers.

Exposure therapy has been proven as an effective treatment for people who have a fear of bees. It is recommended that people place themselves in a comfortable open environment, such as a park or garden, and gradually over a prolonged period of time move closer to the bees. This process should not be rushed, it may take many months spent watching bees before people feel comfortable in their presence.

Apiphobia is one of the zoophobias prevalent in young children and may prevent them from taking part in any outdoor activities. Older people control the natural fear of bees more easily. However, some adults face hardships of controlling the fear of bees.

A recommended way of overcoming child's fear of bees is training to face fears (a common approach for treating specific phobias). Programs vary.

BII phobia is one of the more common psychiatric disorders, affecting about 3 to 4% of the general population, and in about 80% of the BII phobia cases, the patient experiences syncope or presyncope. After a random survey was completed in Aligarh, India, with 1648 male and 1613 female, it was found that a significantly higher percentage of females compared to males had BII phobia; 23.36% of females were diagnosed with BII phobia while only 11.19% of males were diagnosed. Females also fainted more often than males, at 64.09% compared to a male rate of 39.4%.

Furthermore, only 5.3% of BII phobia patients reported to have visited the hospital once or twice for consultation about BII phobia, however, without engaging in any kind of treatment.

Another study, involving participants from all 50 states and the District of Columbia, ages 65 years and older, found that a total of 386 participants disclosed having BII Phobia throughout their whole lifetime, 90% of those cases consisted of patients dealing with BII Phobia as well as other lifetime fears.

Education is the most common treatment, although psychotherapy, including cognitive-behavioral therapy, is indicated when the fear becomes so severe as to cause dysfunction for the individual who suffers from the phobia.

Many mageirocophobes fear the process: cutting themselves, burning themselves, or even having problems executing the steps needed to successfully render a dish. Some see it as a chore that is overwhelming.

The English suffixes -phobia, -phobic, -phobe (from Greek φόβος "phobos", "fear") occur in technical usage in psychiatry to construct words that describe irrational, abnormal, unwarranted, persistent, or disabling fear as a mental disorder (e.g. agoraphobia), in chemistry to describe chemical aversions (e.g. hydrophobic), in biology to describe organisms that dislike certain conditions (e.g. acidophobia), and in medicine to describe hypersensitivity to a stimulus, usually sensory (e.g. photophobia). In common usage, they also form words that describe dislike or hatred of a particular thing or subject (e.g. homophobia). The suffix is antonymic to -phil-.

For more information on the psychiatric side, including how psychiatry groups phobias such as agoraphobia, social phobia, or simple phobia, see phobia. The following lists include words ending in "-phobia", and include fears that have acquired names. In some cases, the naming of phobias has become a word game, of notable example being a 1998 humorous article published by "BBC News". In some cases, a word ending in "-phobia" may have an antonym with the suffix "-phil-", e.g. Germanophobe / Germanophile.

A large number of "-phobia" lists circulate on the Internet, with words collected from indiscriminate sources, often copying each other. Also, a number of psychiatric websites exist that at the first glance cover a huge number of phobias, but in fact use a standard text to fit any phobia and reuse it for all unusual phobias by merely changing the name. Sometimes it leads to bizarre results, such as suggestions to cure "prostitute phobia". Such practice is known as content spamming and is used to attract search engines.

An article published in 1897 in "American Journal of Psychology" noted "the absurd tendency to give Greek names to objects feared (which, as Arndt says, would give us such terms as klopsophobia – fear of thieves, triakaidekaphobia – fear of the number 13...".

Frigophobia is defined as a persistent, abnormal, and unwarranted fear of coldness despite conscious understanding by the phobic individual and reassurance by others that there is no danger. It is also known as cheimaphobia or cheimatophobia.

Arachnophobia is the fear of spiders and other arachnids such as scorpions.

Specialists may prefer to avoid the suffix "-phobia" and use more descriptive terms such as personality disorders, anxiety disorders, and avoidant personality disorder.

Digital hoarding (also known as e-hoarding) is excessive acquisition and reluctance to delete electronic material no longer valuable to the user. The behavior includes the mass storage of digital artifacts and the retainment of unnecessary or irrelevant electronic data. The term is increasingly common in pop culture, used to describe the habitual characteristics of compulsive hoarding, but in cyberspace. As with physical space in which excess items are described as "clutter" or "junk," excess digital media is often referred to as "digital clutter."

Fear of bees (or of bee stings), technically known as melissophobia (from , "melissa", "honey bee" + , "phobos", "fear") and occasionally misspelled as melissaphobia and also known as apiphobia (from Latin "apis" for "honey bee" + "", "phobos", "fear"), is one of the common fears among people and is a kind of specific phobia.

Most people have been stung by a bee or had friends or family members stung. A child may fall victim by treading on a bee while playing outside. The sting can be quite painful and in some individuals results in swelling which may last for several days, and can also provoke allergic reactions such as anaphylaxis, so the development of loathsome fear of bees is quite natural.

Ordinary (non-phobic) fear of bees in adults is generally associated with lack of knowledge. The general public is not aware that bees attack in defense of their hive, or when accidentally squashed, and an occasional bee in a field presents no danger. Moreover, the majority of insect stings in the United States are attributed to yellowjacket wasps, which are often mistaken for a honeybee.

Unreasonable fear of bees in humans may also have a detrimental effect on ecology. Bees are important pollinators, and when, in their fear, people destroy wild colonies of bees, they contribute to environmental damage and may also be the cause of the disappearing bees.

The renting of bee colonies for pollination of crops is the primary source of income for beekeepers in the US, but as the fears of bees spread, it becomes hard to find a location for the colonies because of the growing objections of local population.

The fear of flying may be created by various other phobias and fears:

- Fear of crashing, which in rare cases will cause death, is the most common reason for the fear of flying.

- Fear of closed in spaces (claustrophobia), such as that of an aircraft cabin

- Fear of heights (hypsophobia)

- Feeling of not being in control

- Fear of vomiting, where a person will be afraid that they'll have motion sickness on board, or encounter someone having motion sickness and have no control over it (such as escaping it)

- Fear of having panic attacks in certain places, where escape would be difficult and/or embarrassing (agoraphobia)

- Fear of hijacking or terrorism

The cause of BII phobia is not well known. Some studies show that specific genes make one more vulnerable to the phobia. Other studies suggest that just like any other phobia, BII phobia could be caused by a traumatic experience (Chapman). It has been proved that social stress amplifies BII symptoms, however, it is not a main cause.

Fear of flying is a fear of being on an airplane (aeroplane), or other flying vehicle, such as a helicopter, while in flight. It is also referred to as flying phobia, flight phobia, aviophobia or aerophobia (although the last also means a fear of drafts or of fresh air).

Fear of flying may be a distinct phobia in itself, or it may be an indirect combination of one or more other disorders, such as claustrophobia (a phobia of being restricted, confined, or unable to escape) or acrophobia (anxiety or dread of being at a great height). It may have other causes as well, such as agoraphobia (especially the type associated with having a panic attack in a place they can't escape from). It is a symptom rather than a disease, and different causes may bring it about in different individuals.

This phobia receives more attention than most other phobias because air travel is often difficult for people to avoid—especially in professional contexts—and because it is common, affecting a significant minority of the population. Inability to maintain emotional control when aloft may prevent a person from going on vacations or visiting family and friends, and it can cripple the career of a businessperson by preventing them from traveling on work-related business.

Digital hoarding stems from a variety of individual traits and habits, corporate conditions, and societal trends:

- Some individuals experience anxiety when faced with disposing of digital items, particularly if they fear losing something important.

- Many digital hoarders don't know how to organize their digital content or aren't in the habit of doing so, and they lack a methodology for determining which content is worth keeping.

- Keeping all of one's digital files requires less time and effort than evaluating and deleting them.

- Many businesses rely on email correspondence for decision-making and formal approvals, so employees are often careful to keep work emails in case they are needed to verify a decision later.

- Data storage devices are now so large and inexpensive that individuals and companies often do not feel the need to save data selectively.

- The widespread availability and rapid dissemination of open content on the Internet makes it easier for users to obtain digital media, which can accumulate more quickly than ever.

- Since digital media do not take up physical space, they're less likely to be perceived as clutter, and users can more easily forget the extent of what they own.

- Unlike many physical items, electronic content does not die or decay on its own; users must consciously choose to delete it.

Fear of mice and rats is one of the most common specific phobias. It is sometimes referred to as musophobia (from Greek "μῦς" "mouse") or murophobia (a coinage from the taxonomic adjective "murine" for the family Muridae that encompasses mice and rats), or as suriphobia, from French "souris", "mouse".

The phobia, as an unreasonable and disproportionate fear, is distinct from reasonable concern about rats and mice contaminating food supplies, which may potentially be universal to all times, places, and cultures where stored grain attracts rodents, which then consume or contaminate the food supply.

Phobias are a common form of anxiety disorders and distributions are heterogeneous by age and gender. An American study by the National Institute of Mental Health (NIMH) found that between 8.7 percent and 18.1 percent of Americans suffer from phobias, making it the most common mental illness among women in all age groups and the second most common illness among men older than 25. Between 4 percent and 10 percent of all children experience specific phobias during their lives, and social phobias occur in one percent to three percent of children and adolescents.

A Swedish study found that females have a higher incidence than males (26.5 percent for females and 12.4 percent for males). Among adults, 21.2 percent of women and 10.9 percent of men have a single specific phobia, while multiple phobias occur in 5.4 percent of females and 1.5 percent of males. Women are nearly four times as likely as men to have a fear of animals (12.1 percent in women and 3.3 percent in men) — a higher dimorphic than with all specific or generalized phobias or social phobias. Social phobias are more common in girls than in boys, while situational phobia occurs in 17.4 percent of women and 8.5 percent of men.
