Researchers from Pennsylvania State University studied the effect of UVR exposure with sunscreen or sweat on nitric oxide's ability to promote vasodilation of skin blood vessels.
Both pre- and postexposure skin samples were obtained directly and 24 hours following UVR exposure.
Biopsies of the UVR exposed areas of skin showed that, for the group repeatedly exposed to UVR, considerable DNA damage was found on the areas that received no sun protection, even though the UVR dose was very low.
Five days of exposure to high dose UVR with the sunscreen at 2mg/cm2 showed significantly less damage than just one day's low UVR dose exposure without sunscreen across all samples.
UVR can also increase the risk of developing skin cancer.
There is a direct correlation between the geographic distribution of UV radiation (UVR) and the distribution of indigenous skin pigmentation around the world.
New Zealand public health efforts aim to reduce sunburn by encouraging citizens to engage in SunSmart outdoor behaviour including limiting outdoor sun exposure during peak UVR periods, wearing protective clothing and sun protective broad brimmed, bucket, or Legionnaire's hats, using 30SPF+ sunscreen, and wearing sunglasses that meet Australian and New Zealand standards [23-27].
According to pattern of ultraviolet radiation (UVR) exposure, three distinct forms are defined: a) intermittent (recreational); b) chronic (occupational); and c) cumulative (total) exposure.4 This categorization has been proven to be of great importance in terms of their impact in the development of various skin malignancies, such as BCC, squamous cell carcinoma (SCC) and malignant melanoma.
Exposure to the sun and other sources of ultraviolet radiation (UVR) without sufficient protection is a well-established cause of skin cancer.
Ultraviolet radiation (UVR) is typically defined within the waveband 100 to 400nm (1) and is sub-divided into UVC (100-280nm) which is absorbed by stratospheric oxygen, UVB (280-315nm), much of which is absorbed by atmospheric ozone and UVA (315-400nm) which is the least energetic waveband and constitutes around 95% of total terrestrial UVR.
Ultraviolet radiation (UVR), the most significant spectrum classification and a known carcinogen (Ananthaswamy & Pierceall, 1990), can be classified into three distinct categories: UV-A, UV-B, and UV-C.
