This is 8 Dangers Exposed to Radiation Sunlight |
Ultraviolet rays can give bad on the body and the most visible result of excessive sun exposure are sunburn caused by UVB (ultraviolet B). Excessive sun exposure can also cause cancer of the skin. (See also: Dangers of Ultraviolet rays)
There are many types of skin cancer that can occur due to sun exposure. This adverse impact caused by both ultraviolet A and ultraviolet B. In addition, exposure to radiation or sunlight ternyat also have a role on the incidence of eye diseases ranging from cataracts to malignancy. (See also: Danger of direct sunlight)
The following will discuss the impact of solar radiation hazards:
1. Melanoma
Melanoma is a malignancy of skin malignancy that occurs in the pigment-producing cells (melanocytes). Melanoma occurs primarily in the skin, but can also be found in the eyes, ears, gastrointestinal tract, mucous membranes of the mouth and genitals. The incidence of melanoma is less than 5% of the total skin cancer. However, melanoma is the biggest cause of skin cancer mortality worldwide. The most common cases in the white race over the race premises dark skin. (See also: Types of disease biscuits and pictures - Danger of sunlight during the day)
Ray effect ultaraviolet suspected carcinogenic (causing cancer) that cause mutations of genes in normal melanocytes towards malignancy. The development of melanoma is caused multifactorial associated with several risk factors, such as sun sensitivity, excessive sun exposure, and history are often exposed to scorching as a child.

2. Basal Cell Carcinoma
Is one type of skin cancer. Genesis common in whites tend and grow because of the influence of long sun exposure. Regions often experience facial cancer is the most common due to sun exposure. (See also: Due to lack of Vitamin D)
The exact cause is unknown, but suspected factors are age, race, genetic, chemical, burn scars, chronic irritation and ultraviolet radiation, especially UVB. The number of events is 80% of all skin cancer cases. (See also: Drug allergy itch)
3. Solar keratosis (Actinic Keratosis)
Is a skin disorder due to long exposure to solar radiation. Solar (Actinic) keratosis can develop into squamous cell carcinoma (one epithelial malignancy). Genesis common in fair-skinned people, middle-aged people and people who are sensitive to sunlight. (Read also: Healthy food for the skin)
Beginning disorder tibul still small and the skin feels rough like holding sand paper. Eventually abnormalities will swell look red and scaly. Exposure to sunlight (particularly UVB) causes DNA mutations in keratin cells (keratinocytes). (See also: Drug itching)
4. Sunburn (skin burns)
Sunburn is erythema (redness of the skin) which is a reaction or the impact of sunlight on the skin common. Exposure to sunlight (particularly UVB) Acute causes dilation of blood vessels (vasodilation). It is driven by the release of inflammatory mediators that are stimulated by sunlight. (See also: Various skin diseases)
Sunburn effect mostly is due to reaction of immune cells in the skin that releases histamine in large quantities. Histamine then causes blood vessels to dilate and the occurrence of acute inflammation. Some types of skin cells in certain stages of exposure, can also undergo cell death, thus causing exfoliation. Some opinions say that sunburn included in this type of first-degree burns. Read also: Foods containing Vitamin D super high)
5. Cataract cortical
Cataract is a process that impaired vision in which the views can be vague, there are even darker cloudy blotches (not seen). On a normal day even patients complain frequently experience a glare if there is a light approaching (such as when driving). Cataracts occur due to the calcification process in the lens of the eye. The cause of cataracts is partly due to age factor, drugs and the dangers of solar radiation. (See also: The danger of seeing the Sun directly)

Some theories say, sunlight causes damage to the enzyme useful in the cell proteins of the lens. Securities absorbed heat also causes albumin to be white and opaque, causing cataracts. (See also: The characteristics of eye cataracts)
6. Pterygium (membrane of the eye)
Pterygium is a state where the growth of the membrane covering the cornea. The membrane is a tissue when grown fibrovaskular that resemble wings on subkonjungtuva (white part) of the eye. Contributing factor is often a history of trauma, ultraviolet exposure and infection. (See also: Hazard rubbed his eyes with his hands)
Genesis common around the area near katulistiva (area of high sun exposure). Sunlight (particularly UVB) causing gene mutations on basal cells in the limbus of the cornea. The result is the growth of collagenase and excessive angiogenesis. (See also: the symptoms of Cataracts)
7. The ferocity of the cornea and conjunctiva eye
UV rays cause radiation sickness is most often in the eye. UV rays are damaging the corneal epithelium of the cornea (such as sunburn). The inflammatory response (inflammation) occurs in the form of edema and congestion of the conjunctiva and corneal epithelium. (See also: Hazard view solar eclipse in person)
One malignancy that can happen is epidermoid carcinoma of the bulbar conjunctiva. The number of events common in tropical and subtropical regions. Other cancers that can occur is kasinoma squamous cells in the conjunctiva. (See also: Abnormalities that occur in the eye)
8. Reactivation of herpes labialis (Herpes Mouth)
Diseases caused by the Herpes simplex virus HSV (Herpes Simplex Virus). There are two types of HSV, HSV type-1 usually strikes around the oral (mouth) or outside the genital area, while HSV-2 usually strikes genital (sex). HSV attacked by infecting human nerve. Herpes labialis signs or blisters. (See also: Cause Herpes)
In a study conducted by researchers from Kobe University Graduate School of Medicine in Japan, said the sun plays a role in the incidence of herpes labialis. From the results, the incidence of herpes labialis increases during the summer. (See also: Herpes Virus)
Allegedly negetif UV light impact on the human immune system. Others say HSV UV rays stimulate the nerve endings of the ganglion of people who were infected before. (See also: The disease should not be exposed to sunlight)
The principle of prevention of disease is avoid exposure to ultraviolet rays. Things we can do is reduce the activity under the blazing sun. If unavoidable, use a sunscreen with SPF + 30, use cover the body (eg, long pants and a jacket to cover the neck). Use hats to avoid exposure to the face, and use goggles to protect the eyes Sunglasses.
