Sunlight & UV To inform people about the risk one can expect from UV rays, the National Weather Service and the U.S. Environmental Protection Agency (EPA) have developed a daily UV Index, which is based partly on this climatology. UV The index ranges from 0 to 11+ and the values are grouped into various exposure categories. Historic policies such as the Montreal Protocol and the Copenhagen Amendment have already had a positive impact on the number of new skin cancer diagnoses, estimated to have prevented thousands of future cases (14). Sunscreens are not intended to increase sun exposure time but to increase protection during unavoidable exposure. UV The immune system is vulnerable to modification by environmental agents such as UV radiation, which appears to diminish the effectiveness of the immune system by changing the activity and distribution of the cells responsible for triggering immune responses. A higher index value indicates a greater potential for harmful effects to the skin and eyes. The Global Solar UV Index (UVI) is a simple measurement of the UV radiation level at the Earth's surface. Wear sunglasses on bright days. Global Solar UV Index Taking these factors into account, the UV Index predicts the level of solar UV radiation and indicates the risk of overexposure on a scale from 0 (low) to 11 or more (extremely high). Migration patterns over the past few hundred years have created a scenario in which most people's skin pigmentations are no longer suited to their environments.

The UV Index provides a forecast of the expected risk of overexposure to UV radiation from the sun. A tan results from your body defending itself against further damage from UV radiation. Small amounts of UV radiation are beneficial to people, and play an essential role in the production of vitamin D. However, overexposure to UV radiation is responsible for two major public health problems: skin cancer and cataract. So, it seems that changes to our personal, cultural, and global habits and values need to be made to turn the trend of increased skin cancer cases in the opposite direction. As the rays interact with the cells in our skin, they cause disruptions and damage to the cells DNA. Aside from the geographical location of where we live, cultural practices always play a major role in our sun protection practices and ideologies. Stay in shade near midday when the Sun is strongest. Bright surfaces, such as sand, water, and snow, will increase UV exposure. The author, Claire Bonneau, is a medical writer and certified trauma operating room nurse. Index A dark tan on white skin only offers an SPF of about 4. Figure 4. A sunburn can happen within minutes or over the course of several hours. The map is created daily from National Weather Service forecast data. Moderate mean UVI values occur between 30 and 48 N and high UVI south of 35 N. Additionally, very high mean UVI up to 7.8 are detected south of 32 N. Figure 3. As our ozone layer continues to thin, the amount of UV exposure will only increase in these regions, resulting in worse health outcomes for the people living in these warmer climates. This gives a weighted figure called the Diffey-weighted UV irradiance (DUV) or the erythemal dose rate. Bright surfaces, such as sand, water, and snow, will increase UV exposure. These data come from Emory Universitys Environmental Remote Sensing Group at the Rollins School of Public Health. March. An official website of the United States government. Trouble with this form?

Generously apply broad spectrum SPF 15+ sunscreen every 1.5 hours, even on cloudy days, and after swimming or sweating. As the global cases of skin cancer continue to trend in the wrong direction, it is time that we take action before the number of cases overwhelms our healthcare systems. A lock (LockA locked padlock) or https:// means youve safely connected to the .gov website. Ultraviolet index Take all precautions because unprotected skin and eyes can burn in minutes. Up to 80% of solar UV radiation can penetrate light cloud cover. Haze in the atmosphere can even increase UV radiation exposure. [14], After sporadic attempts by various meteorologists to define a "sunburn index" and growing concern about ozone depletion, Environment Canada scientists James B. Kerr, C. Thomas McElroy, and David I. Wardle invented the modern UV index in Toronto, Ontario. UV Index July. The erythemal weighting factors applied to these figures are 1.0, 0.22, and 0.003 respectively. Sunlight Exposure UV radiation levels are influenced by: Sun elevation: the higher the sun in the sky, the higher the UV radiation level. On Dec. 29, 2003, a world-record UV index of 43.3 was detected at Bolivia's Licancabur volcano. A marked increase in the incidence of skin cancer in fair-skinned populations worldwide is strongly associated with excessive UV radiation exposure from the sun and possibly artificial sources such as sunbeds.
