Heliophobia

Heliophobia (from Greek helios, "sun") is the fear of the, , or any.

Causes
This phobia, like all phobias, originates from a traumatic experience in the past, such as a severe sunburn.

The Pacific Health Center suggested that these people have been staying away from the sunlight because of the growing fears with skin cancer. This is not technically heliophobia, but simply an unfounded and illogical solution. , if it includes an of being harmfully affected by exposure to the sun or to bright lights, can also cause heliophobia. It should be noted that forms of heliophobia based on such irrational fears can cause the sufferer to eventually develop a fear of being in public or a fear of people in general by association, as a crippling fear of bright light can significantly limit the places a heliophobe can comfortably visit, as well as prevent that person from going outside during the daytime, when most other people are active.

Other medical conditions such as (an eye disorder that results in extreme optic sensitivity to sunlight and bright lights) and, which causes the skin to be overly sensitive to sunlight to the point of causing blisters, can result in heliophobia if the sufferer begins to associate pain and discomfort with bright lights.

Effects
Sufferers may cover themselves with long, protective clothing or carry a sun parasol when going outdoors during the daytime, or simply never go outdoors at all when the sun is out, depending on the severity of the fear. Since sufferers stay indoors more than non-sufferers, it will make them more prone to becoming vitamin D deficient, as well as depression caused by a combination of vitamin D deficiency, isolation and feelings of alienation from other people, and a continuously dark environment. However, a vitamin deficiency can be helped by taking vitamin D supplements or by consuming vitamin D fortified foods.

Symptoms
The symptoms of heliophobia depends on the person. Mild sufferers may feel uncomfortable, shaky, nauseated, or numb. Severe sufferers may feel anxious or suffer panic attacks. Other symptoms include heightened senses, lack of focus, feeling trapped, irregular heartbeat, air hunger, rapid breathing, parched mouth, sweating, muscle cramps, and physical discomfort that is not actually caused by bodily injury, but is a physical manifestation of the panic and fear that the heliophobic person experiences when exposed to light. This physical pain may be expressed, for example, as a phantom sensation of their skin burning under direct sunlight, even when it is visually apparent that their skin is not actually burning any more than healthy skin would as a result of sun exposure, but nonetheless still feels like real pain for the sufferer.

Treatment
Heliophobia can be treated using, , self-help techniques, s, , and relaxation techniques. For people who are severely heliophobic, anti-anxiety meditation is a recommended mode of treatment.
