Indoor tanning is a source of UV radiation, which is known to cause skin cancer, including melanoma [11] [12] [13] and skin aging, [14] and is associated with sunburn, photodrug reactions, infections, weakening of the immune system, and damage to the eyes, including cataracts, photokeratitis (snow blindness) and eye cancer.
[43] [failed verification] UVC is the highest-energy, most-dangerous type of ultraviolet radiation, and causes adverse effects that can variously be mutagenic or carcinogenic. [44] Despite the importance of the sun to vitamin D synthesis, it is prudent to limit the exposure of skin to UV radiation from sunlight [45] and from tanning beds. [46]
The primary cause of skin cancer is prolonged exposure to ultraviolet (UV) radiation from the sun or tanning devices. Skin cancer is the most commonly diagnosed form of cancer in humans. [ 11 ] [ 12 ] [ 13 ] There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma . [ 1 ]
Ultraviolet radiation is thought to cause up to 95% of basal and squamous cell carcinomas, and between 70-95% of melanomas in people with fair skin. “Skin cancer is caused by exposing the cells ...
Artificial UV light sources from tanning units and phototherapy treatment units can also trigger PLE. About three-quarters of patients acquire PLE after UV-A exposure only, one-tenth after UV-B exposure only, and the rest after a combination of UV-A and UV-B exposure. [6] People vary in the amount of sun exposure needed to trigger the rash. [15]
This drug is used in photodynamic therapy for many inflammatory skin conditions, where the drug is combined with skin exposure to UV light. Epidemiological studies dating back to the 1970s have shown a strong association between psoralen treatment and skin cancer incidence 5 to 15 years afterwards. [ 5 ]
Exposure to non-ionizing ultraviolet light is a risk factor for developing skin cancer (especially non-melanoma skin cancers), sunburn, premature aging of skin, and other effects. Despite the possible hazards it is beneficial to humans in the right dosage, since Vitamin D is produced due to the biochemical effects of ultraviolet light.
UV radiation has a thermal effect on the skin and eyes and can lead to skin cancer (malignant melanoma) and eye inflammation or cataracts. [269] To protect the skin from harmful UV radiation, such as photodermatosis , acne aestivalis , actinic keratosis or urticaria solaris, normal clothing, special UV protective clothing (SPF 40-50) and high ...
