With some countries like Australia and New Zealand reporting incredibly high average UV index levels, others like Norway and Denmark still have cases despite having much lower UV values. Through migrational habits and evolutionary changes, those who ended up in more northern locations were more likely to develop fairer skin tones. This means that there is a high risk of skin damage from prolonged exposure to sunlight. UV Radiation - Sun - Solaria - Infrared Radiation - Laser. The coldest month in Auckland, New Zealand, is July , with an average high-temperature of 13.8C (56.8F) and an average low-temperature of 10.4C (50.7F) . Vulnerable groups Children are particularly sensitive to UV radiation and require special protection. Out of the 50 holiday hotspots, Sri Lanka has the most dangerous radiation level, with an average score of 11.75[4]. The UV Index is an important vehicle to raise public awareness of the risks of excessive exposure to UV radiation, and to alert people about the need to adopt protective measures. Additionally, wearing broad-spectrum high SPF (sun protection factor) sunscreens while spending any time outdoors is one of the best ways to protect your skin. If you burn easily, cover up and use broad spectrum SPF 15+ sunscreen.

Capable of causing a sunburn on unprotected skin in under 45 minutes, places like Norway and Denmark with an average UV index of 5 or 6 can still be dangerous, especially for those with fair skin tones. Determine which states have laws or policies in place to help reduce exposure to sunlight and UV, particularly among minors. May. Ground reflection: grass, soil and water reflect less than 10% of UV radiation; fresh snow reflects as much as 80%; dry beach sand about 15% and sea foam about 25%. What Might Have Been The project assesses and quantifies health risks, and develops an appropriate response through guidelines, recommendations and information dissemination. 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. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Beyond its scientific objectives, INTERSUN provides guidance to national authorities and other agencies about effective sun awareness programmes. The UV-Index. A changing lifestyle and sun-seeking behaviour are responsible for much of the increase in skin cancers. While the idea of having tanned skin is incredibly popular in Westernized countries like the United States, Canada, and the United Kingdom, other countries have different popular opinions on what is considered to be culturally attractive. However, higher UV Index values may occur due to the variability of the influence parameters (e.g. Table 1 shows the average monthly UV Index across Australia.

The UV Index scale ranges from a low of zero to a high of 11+ in Canada, The highest values occur in southern Ontario, where values of 11, or even 12 on rare occasions, have occurred. Without the higher amounts of melanin in the skin, people with fair skin are at an elevated risk for experiencing UV radiation damage to their skin cells. 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.

The UV index climatology shows how much UV exposure a person could get on average during each month. Up to 80% of solar UV radiation can penetrate light cloud cover. The UVI is usually presented as a forecast of the maximum amount of UV radiation expected to reach the Earth's surface at solar noon. UV rating 11+ Any rating of 11 or higher is considered to be extreme levels of UV radiation exposure. webmaster: Paul Przyborski | NASA official: Robert Levy. Research has found a 4x increase in minimum dose to sunburn from subjects in the US compared to subjects in Taiwan.[29]. The values of the Index range from zero upward and the higher the Index value, the greater the potential for damage to the skin and eye, and the less time it takes for harm to occur. In Heraklion, Greece has an average UV index of 12.

Tracking sunlight and UV exposures in a standard way can help us identify regions of high exposure and to track trends over time. 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). In 2005, Australia[22] and the United States[23] However, higher UV Index values Simple precautions will prevent both short-term and long-term damage of UV radiation exposure, while still making the time spent outdoors enjoyable.

It has been designed to indicate the potential for adverse health effects and to encourage people to protect themselves. Heraklion, Greece has an average UV index of 12. UV radiation levels are influenced by: Sun elevation: the higher the sun in the sky, the higher the UV radiation level. [1] The purpose of the UV index is to help people effectively protect themselves from UV radiation, which has health benefits in moderation but in excess causes sunburn, skin aging, DNA damage, skin cancer, immunosuppression,[2] and eye damage, such as cataracts. Africa; Many experts believe that the increased prevalence of skin cancer in modern fair-skinned Aussies and Kiwis is in part due to their European ancestors. 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. The UVI was developed through an international effort by WHO in collaboration with the United Nations Environment Programme (UNEP), the World Meteorological Organization (WMO), the International Commission on Non-Ionizing Radiation Protection (ICNIRP), and the German Federal Office for Radiation Protection.

The amount of UV radiation that you are exposed to throughout the day can be affected by your geographic location and the weather forecast each day. The maps below show monthly average UV Index values for the United States. A higher index value indicates a greater potential for harmful effects to the skin and eyes. Depletion of the ozone layer, which provides a protective filter against UV radiation, may further aggravate the problem. Lets explore how human genetics (and the impact of modern pollution) are contributing to the increased numbers of skin cancer diagnoses around the world. 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.
