Heliophobia is an abnormal, extreme, and persistent fear of the sun.
This word is also used to refer to dread or avoidance of sunlight. In some cases excessive sensitivity to sunlight can be involved. In such cases it is usually more accurate to use the name of the relevant clinical conditions (or conditions) where known, than the word heliophobia.
More general information about extreme fears such as Heliophobia:
Extreme fears (phobias) such as heliophobia can lead to a variety of disturbing symptoms such as breathlessness, difficulty in thinking or speaking clearly, dizziness, a dry mouth, a fear of dying, a fear of "going mad" or losing control, a sense of feeling sick, the inability to concentate, inability to make decisions that are usually simple, nausea, palpitations, shaking, sweating profusely, or a severe anxiety attack. Not everyone who has heliophobia is affected by all possible symptoms, and some individuals may also have other reactions.
Even though many adult sufferers of heliophobia (and/or other fears/phobias) are aware that their fears are unreasonable, many still experience severe anxiety even when just thinking about the subject or situation they fear. However, phobias such as heliophobia are known and are a relatively common form of anxiety disorder that may be treated conventionally using cognitive behavioral therapy including exposure and fear reduction techniques. Drugs may also be offered, typically anti-anxiety or anti-depressants - particularly during the early stages of treatment. Other forms of treatment offered may include hypnotherapy, Emotional Freedom Technique (EFT) or other similar therapies.
