The pursuit of a healthy and fashionable way of life is in the majority of young people, without rebuke. Today, the sun has become a number of white-collar workers and the rich people's fashion beauty, it seems that the United States and the United States and Chinese people are in line with the west, what is a good foreign, but I know that this is a great potential hidden danger.

In fact, this is the western sun less sunlight or winter sun, to promote skin metabolism, to supplement vitamin D body, children and the elderly or bedridden patients appropriate to the sun, conducive to the synthesis of calcium and calcium absorption, the body health is good. Medicine for its capacity can increase the pigment pigment producing cells for the treatment of some superficial parts of the diseases such as vitiligo, melanin in restricted range UV blocking the harm to the human body, a proper skin is also conducive to the prevention of days after sunburn.

Generally speaking, there are different wavelengths of light in the sunlight. Effect of skin darkening light is longer wavelength ultraviolet A (wavelength 315-400 nm) and short wavelength ultraviolet B (wavelength 280-315 nm), ultraviolet A can penetrate into deep skin, which is visible. Now popular from the west of the sun bath bed lamp is mainly the use of its emission of higher intensity of ultraviolet A and some ultraviolet B, simulated solar spectrum to make the skin in a short period of rapid tanning. Many people think that tanned skin for bodybuilding, white skin prone to melanoma or cancer, a short time the actual human darken the skin have great harm and danger to human body.

A person when the summer began to wear short pants, will find a bra, covering parts of the skin white, delicate, texture, smooth and elastic, and the sun had darker skin drying, not smooth, some scaling. This is due to the long-term ultraviolet A irradiation can cause the skin collagen fibers deformation, the surface of the skin keratinocytes easily aging necrosis, moisture evaporation, dry skin becomes rough, no flexibility, long is prone to wrinkles and other light aging. Some people will therefore appear various sizes of spots on the face, there are some telangiectasia, make beautiful face instantly leave blemishes, beautiful discount.

You will find the comparison in outdoor labor of farmers and working indoors counterparts, the former than the latter is older, and to the elderly will obviously feel the hand and face senile plaques, and rarely long? Are the days and months multiplying ultraviolet. Ultraviolet B will cause skin erythema, edema and inflammatory reaction in a very short period of time, causing skin sunburn or allergies, especially white skin are more careful sunbathing. We often encounter the face of the Yin and Yang face of white-collar workers, while the face white, black face, and aging fast, which is related to the intensity of the fluorescent light.

We all know: ultraviolet radiation is used to disinfect, also can be used for the treatment of vitiligo, eczema and psoriasis, application limited, long skin sunburn, especially the two kinds of ultraviolet radiation will damage the interaction in the epidermal cells of DNA induced gene mutation, proto oncogene activation, which leads to the occurrence of skin cancer the. Why are so many skin cancers such as melanoma in the west, that is, rather than sunbathing, white skin is easy to absorb ultraviolet light, increase skin sunburn and skin superficial epidermal cell mutation. The investigation found that the international agency for research on cancer, if you accept the artificial sun exposure before the age of 30, the risk of skin cancer will surge 75%. In fact, highly malignant melanoma, squamous cell carcinoma and basal cell carcinoma of the skin cancer with long-term exposure to ultraviolet light has a great relationship.

In addition, the medical treatment of ultraviolet radiation during eye protection, patients need to wear special glasses to protect the eyes. If popular with sunbathing, and standardized management, UV is very easy on the eyes and cause effect, causing cataracts, pterygium (a white excrescences on the cornea) and inflammation of the eye such as light and light conjunctivitis keratitis. In addition, such as long-term exposure to ultraviolet light, can inhibit the body's immune system, may lead to lymphoma or other infectious diseases such as infectious diseases. If you only consider the skin color changes in the short term, eye inflammation and other diseases are accompanied by, it is not a healthy fashion beauty way.

Besides, it's not the right person to sunbathe. There are six different types of skin (I-VI) depending on the skin's susceptibility to sunburn. I type of skin is the most white skin, that is, repeated exposure to the sun will not have a slight tan skin color. More skin sunburn response. As the population is not suitable for sunbathing: I type and II type color; under the age of 18 children; there are a lot of people on the spot or mole; easily freckles; in childhood often sunburn history; a premalignant or malignant skin injury; the skin is easily injured by the sun or light sensitive people such as lupus erythematosus patients; the use of cosmetics or drugs, eating wild herbs and other photosensitive vegetables, because these substances may enhance their sensitivity to UV exposure, time and amount of sunbathing irradiation is not good grasp, it is easy to excessive skin damage or skin allergies and other severe reactions.

In fact, even more popular in the United States for sunbathing, sunlamps can also be classified as medical instruments to regulate the management, strict requirements in place must use warning labels, can not use the "safe Tan" and "no harmful light" and "no side effects" and other similar publicity. In China, tanning in popularity, due to lack of legal standards and the corresponding supervision and management, there is a huge risk, for consumers, and social descendants left hidden dangers and risk can not be ignored, should think twice, otherwise, a "Black Sun", bring you is not beautiful temptation and bronze, swept away is your health and life.
