Wind turbine syndrome or wind farm syndrome is a psychosomatic disorder primarily caused by anxiety generated by heightened awareness of turbines – the "nocebo effect" – prompted by proponents of the idea that wind turbines have adverse health effects. While proponents claim that a number of effects including death, cancer and congenital abnormality have been caused by wind farms, the distribution of recorded events correlates with media coverage of wind farm syndrome itself, and not with the presence or absence of wind farms. It is not recognised by any international disease classification system and does not appear in any title or abstract in the United States National Library of Medicine's PubMed database. The Center for Media and Democracy's "SourceWatch" website has identified at least one Australian fossil fuel industry funded astroturfing group as involved in promoting the idea of wind turbine syndrome. An investigation led to the foundation being stripped of its status as a health promotion charity.

A 2011 literature review stated that wind turbines can be associated with some health effects, such as sleep disturbance, and argued that the health effects reported by those living near wind turbines were probably caused not by the turbines themselves but rather by "physical manifestation from an annoyed state."

Eighteen research reviews about wind turbines and health, published since 2003, all concluded that there was very little evidence that wind turbines were harmful in any direct way.

A meta study published in 2014 concluded:

- Infrasound is emitted by wind turbines. The levels of infrasound at customary distances to homes are typically well below audibility thresholds.

- Components of wind turbine sound, including infrasound and low-frequency sound, have not been shown to present unique health risks to people living near wind turbines.

- Among the cross-sectional studies of better quality, no clear or consistent association is seen between wind turbine noise and any reported disease or other indicator of harm to human health.

- Annoyance associated with living near wind turbines is a complex phenomenon related to personal factors. Noise from turbines plays a minor role in comparison with other factors in leading people to report annoyance in the context of wind turbines

In Ontario, Canada, the Ministry of the Environment created noise guidelines to limit wind turbine noise levels 30 metres away from a dwelling or campsite to 40 dB(A). These regulations also set a minimum distance of for a group of up to five relatively quiet [102 dB(A)] turbines within a radius, rising to for a group of 11 to 25 noisier (106-107 dB(A)) turbines. Larger facilities and noisier turbines would require a noise study.

Modern wind turbines produce significantly less noise than older designs. Turbine designers work to minimise noise, as noise reflects lost energy and output. Noise levels at nearby residences may be managed through the siting of turbines, the approvals process for wind farms, and operational management of the wind farm.

The subject of mouthpiece pressure is closely related to the issue of embouchure collapse/embouchure overuse.

It has long been argued that excessive mouthpiece pressure is a cause of embouchure problems and can be a factor in causing embouchure collapse. However, the pressure of the mouthpiece is not static during playing: it increases the higher in the register a player plays and the louder volume level. Also, a little mouthpiece pressure is essential to provide a seal between the player's embouchure and the instrument; without this, all the air would escape before entering the instrument and no sound would be emitted (brass instruments are dependent on an airflow to produce sound).

Embouchure collapse is far more common among trumpet and horn players. Both of these instruments have mouthpieces with a small circumference, and therefore the pressure is presumably greater, as the force of the mouthpiece on the face is more concentrated. This is in accordance with the principle of physics that pressure is the amount of force divided by the area on which the force is exerted.

As a result of a lack of scientific evidence (no scientific study into mouthpiece pressure as a cause of embouchure collapse has ever been done), the equally valid argument that all brass players can suffer embouchure collapse, and the subjective (not static) nature of mouthpiece pressure, knowledge of mouthpiece pressure as a cause of embouchure collapse is limited.

Embouchure collapse caused by focal dystonia can be diagnosed medically; embouchure collapse caused by embouchure overuse, however, is generally speaking not considered to be a specifically medical issue. A difficulty in diagnosis is that when a brass player describes the symptoms to a doctor or dentist (as is often the case), the medical practitioner does not fully understand what the patient means. This is because brass players learn their embouchure by "feel," and therefore words have a limited ability to describe embouchure problems, especially if the person listening to the description is not a brass player and has a limited knowledge of the embouchure.

Also, in less severe cases, the player may only be able to feel what is wrong while playing. Many players with an embouchure problem will, once they have realized that it is more than a simple case of tired lips, wish to refrain from playing. The fact that around 24 muscles are employed in forming a brass embouchure, and that each will change slightly as a player struggles to play when experiencing embouchure problems, mean that what players describe as being wrong will have not only worsened their condition when they play, but will be different each time they do so.

In the severest cases, the pain caused by embouchure overuse can be felt even when not playing; in some cases, other symptoms will manifest, such as loss of tissue and damaged nerves. This, however, occurs only in the rarest and most extreme circumstances and usually signals the end of the player's career.

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.

Hay fever was relatively uncommon in Japan until the early 1960s. Shortly after World War II, reforestation policies resulted in large forests of cryptomeria and Japanese cypress trees, which were an important resource for the construction industry. As these trees matured, they started to produce large amounts of pollen. Peak production of pollen occurs in trees of 30 years and older. As the Japanese economy developed in the 1970s and 1980s, cheaper imported building materials decreased the demand for cryptomeria and Japanese cypress materials. This resulted in increasing forest density and aging trees, further contributing to pollen production and thus, hay fever. In 1970, about 50% of cryptomeria were more than 10 years old, and just 25% were more than 20 years old. By 2000, almost 85% of cryptomeria were over 20 years old, and more than 60% of trees were over 30 years old. This cryptomeria aging trend has continued since then, and though cryptomeria forest acreage has hardly increased since 1980, pollen production has continued to increase. Furthermore, urbanization of land in Japan led to increasing coverage of soft soil and grass land by concrete and asphalt. Pollen settling on such hard surfaces can easily be swept up again by winds to recirculate and contribute to hay fever. As a result, approximately 25 million people (about 20% of the population) currently suffer from this type of seasonal hay fever in Japan.

No one is born with a fear of the wind. This mental disorder is most commonly the result of psychological trauma caused by a negative experience with wind in the afflicted person's past. The experience may be remembered, or it may be "imprinted" on the subconscious mind of the traumatized person.

People who suffer from this phobia tend to be frightened by changes in the weather, such as storms. They are likely to believe that the wind has the potential to kill and destroy. Additionally, they avoid things that remind them of wind, like ocean waves. Ancraophobia is also related to terms like aeroacrophobia, which is the fear of open high places, and anemophobia which is the fear of air drafts.

A sizable industry has developed in Japan around services and products that help people deal with hay fever, including protective wear such as coats with smooth surfaces, masks, and glasses; medication and remedies; household goods such as air-conditioner filters and fine window screens; and even "hay fever relief vacations" to low-pollen areas such as Okinawa and Hokkaido. Some people in Japan use medical laser therapy to desensitize the parts of their nose that are sensitive to pollen.

Wet-tail is a disease in the animal's intestines caused by the bacteria, "Lawsonia intracellularis". Wet-tail is a stress related illness—such stress can be caused by a variety of factors, including:

- Too much handling

- Change in environment

- Change in diet

- Extremely unclean caging

- Being away from mother and/or siblings

- Illness or death of a pair-bond or mate

Ancraophobia, also known as anemophobia, is an extreme fear of wind or drafts. It is rather uncommon, and can be treated. It has many different effects on the human brain. It can cause panic attacks for those who have the fear, and can make people miss out on regular everyday activities. Such as, going outside.

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.

The fear of ghosts in many human cultures is based on beliefs that some ghosts may be malevolent towards people and dangerous (within the range of all possible attitudes, including mischievous, benign, indifferent, etc.). It is related to fear of the dark.

The fear of ghosts is sometimes referred to as phasmophobia and erroneously spectrophobia, the latter being an established term for fear of mirrors and one's own reflections.

Wet-tail or proliferative ileitis, is a disease of hamsters. It is precipitated by stress. Even with treatment, the animal can die within 48–72 hours. Baby hamsters are much more likely to get the disease than older hamsters. It commonly is found when the hamster is being weaned at about four weeks of age.

CRPS can occur at any age with the average age at diagnosis being 42. It affects both men and women; however, CRPS is three times more frequent in females than males.

CRPS affects both adults and children, and the number of reported CRPS cases among adolescents and young adults has been increasing, with a recent observational study finding an incidence of 1.16/100,000 among children in Scotland.

Blain was an animal disease of unknown etiology that was well known in the eighteenth- and nineteenth centuries. It is unclear whether it is still extant, or what modern disease it corresponds to.

According to Ephraim Chambers' eighteenth-century "Cyclopaedia, or an Universal Dictionary of Arts and Sciences", blain was "a " (in the archaic eighteenth-century sense of the word, meaning "disease") occurring in animals, consisting in a "Bladder growing on the Root of the Tongue against the Wind-Pipe", which "at length swelling, stops the Wind". It was thought to occur "by great chafing, and heating of the Stomach".

Blain is also mentioned in "Cattle: Their Breeds, Management, and Diseases", published in 1836, where it is also identified as "gloss-anthrax". W. C. Spooner's 1888 book "The History, Structure, Economy and Diseases of the Sheep" also identifies blain as being the same as gloss-anthrax.

Modern scholarship suggests that "gloss-anthrax" was not the same disease as modern-day anthrax, but instead could have been foot-and-mouth disease, or a viral infection with a secondary "Fusobacterium necrophorum" infection. It has also been suggested that it may have been due to a variant strain of true anthrax that is no longer in existence. Other sources also report epizootics known as "blain" or "black-blain" in the 13th and 14th centuries, but it is not clear if the disease involved was the same as "gloss-anthrax".

Good progress can be made in treating CRPS if treatment is begun early, ideally within three months of the first symptoms. If treatment is delayed, however, the disorder can quickly spread to the entire limb, and changes in bone, nerve, and muscle may become irreversible. The prognosis is not always good. Johns Hopkins Hospital reports that 77% of sufferers have spreads from the original site or flares in other parts of the body. The limb, or limbs, can experience muscle atrophy, loss of use, and functionally useless parameters that require amputation. RSD/CRPS will not "burn itself out", but if treated early, it is likely to go into remission. Once one is diagnosed with Complex Regional Pain Syndrome, the likelihood of it resurfacing after going into remission is significant. It is important to take precautions and seek immediate treatment upon any injury.

Acrophobia (from the , "ákron", meaning "peak, summit, edge" and , "phóbos", "fear") is an extreme or irrational fear or phobia of heights, especially when one is not particularly high up. It belongs to a category of specific phobias, called space and motion discomfort, that share both similar causes and options for treatment.

Most people experience a degree of natural fear when exposed to heights, known as the fear of falling. On the other hand, those who have little fear of such exposure are said to have a head for heights. A head for heights is advantageous for those hiking or climbing in mountainous terrain and also in certain jobs e.g. steeplejacks or wind turbine mechanics.

Acrophobia sufferers can experience a panic attack in high places and become too agitated to get themselves down safely. Approximately 2–5% of the general population suffers from acrophobia, with twice as many women affected as men.

The majority of patients present in their mid-30s to late 40s. This is likely due to a combination of the slow growth of the bone and the decreased participation in activities associated with surfer's ear past the 30's. However surfer's ear is possible at any age and is directly proportional to the amount of time spent in cold, wet, windy weather without adequate protection.

The normal ear canal is approximately 7mm in diameter and has a volume of approximately 0.8 ml (approximately one-sixth of a teaspoon). As the condition progresses the diameter narrows and can even close completely if untreated, although sufferers generally seek help once the passage has constricted to 0.5-2mm due to the noticeable hearing impairment. While not necessarily harmful in and of itself, constriction of the ear canal from these growths can trap debris, leading to painful and difficult to treat infections.

Prevention of ocular trauma is most effective when soldiers wear polycarbonate eye armor correctly in the battlefield. For Operation Iraqi Freedom and Operation Enduring Freedom, the United States Military have made Ballistic Laser Protective Spectacles (BLPS), Special Protective Eyewear Cylindrical System (SPECS), and Sun/Wind/Dust Goggles (SWDG) available to combatants and associated personnel. These forms of eye protection are available in non-prescription and prescription lenses, and their use has been made mandatory at all times when soldiers are in areas of potential conflict. Despite their proven record of protection against secondary blast trauma, soldier compliance remains low: 85% of soldiers afflicted ocular trauma in the first year of OEF were not wearing their protective lenses at the time of detonation. While 41% of soldiers could not recall whether or not they were wearing eye protection at the time of detonation, 17% of casualties were wearing eye protection while 26% of casualties were not. Among this group, the poorest visual prognoses were documented in individuals who did not wear eye protection. The lack of compliance has been attributed to complaints about comfort, stylishness, and “misting” of the lenses when in the field. BLPS and SPECS offer the same line of protection against secondary trauma as the SWD goggles, and these lenses may overcome the complaints many soldiers have with their military-issue goggles.

Traditionally, acrophobia has been attributed, like other phobias, to conditioning or a traumatic experience. Recent studies have cast doubt on this explanation; a fear of falling, along with a fear of loud noises, is one of the most commonly suggested inborn or "non-associative" fears. The newer non-association theory is that a fear of heights is an evolved adaptation to a world where falls posed a significant danger. The degree of fear varies and the term phobia is reserved for those at the extreme end of the spectrum. Researchers have argued that a fear of heights is an instinct found in many mammals, including domestic animals and humans. Experiments using visual cliffs have shown human infants and toddlers, as well as other animals of various ages, to be reluctant in venturing onto a glass floor with a view of a few meters of apparent fall-space below it. While an innate cautiousness around heights is helpful for survival, an extreme fear can interfere with the activities of everyday life, such as standing on a ladder or chair, or even walking up a flight of stairs.

A possible contributing factor is a dysfunction in maintaining balance. In this case the anxiety is both well founded and secondary. The human balance system integrates proprioceptive, vestibular and nearby visual cues to reckon position and motion. As height increases, visual cues recede and balance becomes poorer even in normal people. However, most people respond by shifting to more reliance on the proprioceptive and vestibular branches of the equilibrium system.

An acrophobic, however, continues to over-rely on visual signals whether because of inadequate vestibular function or incorrect strategy. Locomotion at a high elevation requires more than normal visual processing. The visual cortex becomes overloaded resulting in confusion. Some proponents of the alternative view of acrophobia warn that it may be ill-advised to encourage acrophobics to expose themselves to height without first resolving the vestibular issues. Research is underway at several clinics.

Visual outcomes for patients with ocular trauma due to blast injuries vary, and prognoses depend upon the type of injury sustained. The majority of poor visual outcomes arise from perforating injuries: only 21% of patients with perforating injuries with pre-operative light perception had a final best-corrected visual acuity (BCVA) better than 20/200. Collectively, patients who experienced choroidal hemorrhage, perforated or penetrated globes, retinal detachment, traumatic optic neuropathy, and subretinal macular hemorrhage carried the highest incidence rates of BCVAs worse than 20/200. Reports from Operation Iraqi Freedom (OIF) indicate that 42% of soldiers with globe injuries of any kind had a BCVA greater than or equal to 20/40 six months after injury, and soldiers with intraocular foreign bodies (IOFBs) retained 20/40 or better vision in 52% of studied cases.

Globe perforation, oculoplastic intervention, and neuro-ophthalmic injuries contribute significantly to reported poor visual outcomes. 21% of tertiary centers treating patients exposed to blast trauma reported traumatic optic neuropathy (TON) in their patients, although avulsion of the optic nerve and TON were reported in only 3% of combat injuries. In the event that a victim of globe penetrating trauma cannot perceive any light within two weeks of surgical intervention, the ophthalmologist may choose to enucleate as a preventative measure against sympathetic ophthalmia. However, this procedure is extremely rare, and current reports indicate that only one soldier in OIF has undergone enucleation in a tertiary care facility to prevent sympathetic ophthalmia.

The widespread use of wetsuits has allowed people to surf in much colder waters, which has increased the incidence and severity of surfer's ear for people who do not properly protect their ears.

- Avoid activity during extremely cold or windy conditions.

- Keep the ear canal as warm and dry as possible.

- Ear plugs

- Wetsuit hood

- Swim cap

- Diving helmet

Gephyrophobia is the anxiety disorder or specific phobia characterized by the fear of bridges. As a result, sufferers of gephyrophobia may avoid routes that will take them over bridges.

Some possible explanations of gephyrophobia may be the fear of driving off the bridge, the fear of a gust of wind taking one off the bridge, a fear of the structural integrity of the bridges itself, or the fear that the bridge will collapse if they try to cross it. The fear overlaps with acrophobia, the fear of heights, as gephyrophobia tends to be exacerbated in tall bridges vs. ones close to the water/ground beneath.

Dr. Michael Liebowitz, founder of the Anxiety Disorders Clinic at the New York State Psychiatric Institute, says, "It's not an isolated phobia, but usually part of a larger constellation ... It's people who get panic attacks. You get light-headed, dizzy; your heart races. You become afraid that you'll feel trapped." It is a situational phobia.

The New York State Thruway Authority will lead gephyrophobiacs over the Tappan Zee Bridge. A driver can call the authority in advance and arrange for someone to drive the car over the bridge for them. The authority performs the service about six times a year.

The Maryland Transportation Authority offers a similar service for crossing the Chesapeake Bay Bridge.

The Mackinac Bridge Authority, which oversees the Mackinac Bridge, which connects Michigan’s Upper and Lower peninsulas, will drive one's car across its span for any needy gephyrophobiacs. Some thousand drivers take advantage of this free program each year. Leslie Ann Pluhar had her Yugo blown off that bridge. Later investigation showed the driver had stopped her car over the open steel grating on the bridge's span and that a gust of wind through the grating blew her vehicle off the bridge, although this is not supported by recorded wind speed measurements taken on and around the bridge at the time of the accident.

The term "gephyrophobia" comes from Greek γέφυρα ("gephura") meaning "bridge" and φόβος ("phobos") "fear".

TMD mostly affects people in the 20 – 40 age group, and the average age is 33.9 years. People with TMD tend to be younger adults, who are otherwise healthy. Within the catchall umbrella of TMD, there are peaks for disc displacements at age 30, and for inflammatory-degenerative joint disorders at age 50.

About 75% of the general population may have at least one abnormal sign associated with the TMJ (e.g. clicking), and about 33% have at least one symptom of TMD. However, only in 3.6–7% will this be of sufficient severity to trigger the individual to seek medical advice.

For unknown reasons, females are more likely to be affected than males, in a ratio of about 2:1, although others report this ratio to be as high as 9:1. Females are more likely to request treatment for TMD, and their symptoms are less likely to resolve. Females with TMD are more likely to be nulliparous than females without TMD. It has also been reported that female caucasians are more likely to be affected by TMD, and at an earlier age, than female African Americans.

According to the most recent analyses of epidemiologic data using the RDC/TMD diagnostic criteria, of all TMD cases, group I (muscle disorders) accounts for 45.3%, group II (disc displacements) 41.1%, and group III (joint disorders) 30.1% (individuals may have diagnoses from more than one group). Using the RDC/TMD criteria, TMD has a prevelence in the general population of 9.7% for group I, 11.4% for group IIa, and 2.6% for group IIIa.

It has been suggested that the natural history of TMD is benign and self-limiting, with symptoms slowly improving and resolving over time. The prognosis is therefore good. However, the persistent pain symptoms, psychological discomfort, physical disability and functional limitations may detriment quality of life. It has been suggested that TMD does not cause permanent damage and does not progress to arthritis in later life, however degenerative disorders of the TMJ such as osteoarthritis are included within the spectrum of TMDs in some classifications.
