UV radiation levels vary throughout the year and throughout the country according to: Simple precautions will prevent both short-term and long-term damage of UV radiation exposure, while still making the time spent outdoors enjoyable. An index of 10 corresponds roughly to midday summer sunlight with a clear sky when the UV index was originally designed; now summertime index values in the tens are common for tropical latitudes, mountainous altitudes, areas with ice/water reflectivity and areas with above-average ozone layer depletion. Vital Graphics Series. Sunscreen should be applied to parts of the body that remain exposed, like the face and hands. The clear/sunny sky peak UVI index is reduced by cloud cover. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Haze in the atmosphere can even increase UV radiation exposure. An index of 0 corresponds to zero UV radiation, as is essentially the case at night. These data come from Emory Universitys Environmental Remote Sensing Group at the Rollins School of Public Health. Environment Canada launched it as part of the weather forecast on May 27, 1992, making Canada the first country in the world to issue official predictions of UV levels for the next day. It is primarily used in daily and hourly forecasts aimed at the general public. sun-safe activities is a great way to reduce your risk of developing skin cancer. Long-term effects of UV radiation exposure of the eye may include the development of pterygium (white or creamy opaque growth attached to the cornea), and squamous cell cancer of the conjunctiva. Bright surfaces, such as sand, water, and snow, will increase UV exposure. WebWhen the UV index is presented on a daily basis, it represents UV intensity around the sun's highest point in the day, called solar noon, halfway between sunrise and sunset.This typically occurs between 11:30 and 12:30, or between 12:30 and 13:30 in areas where daylight saving time is being observed. 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 most common types of non-melanoma skin cancers are basal cell carcinomas and squamous cell carcinomas, both of which have a lower mortality rate than melanoma (1).

Multilateral Some 16 million people worldwide are currently blind as a result of cataracts; of these, WHO estimates that as many as 20% may be due to UV radiation exposure. The higher the UV index, the more intense the radiation and the greater the risk of skin damage. The index is a scale of 0 to 16+, with 0 representing minimal UV exposure risk and values higher than 11 posing an extreme risk. As UV radiation can neither be seen nor felt, it is important to provide a tool to raise awareness of the problem and alert people on a daily basis to take prompt, appropriate, protective action. However, sunscreen represents a last line of defence, and should never be used to prolong the duration of sun exposure. Sun elevation: the higher the sun in the sky, the higher the UV radiation level. Unless protective clothing and sunglasses are worn, skin and eyes can be damaged in minutes, It has been designed to indicate the potential for adverse health effects and to encourage people to protect themselves. These values are also representative of the values expected between 11 am and 1 pm local time (12 pm and 2 pm daylight saving time) under clear skies. 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. clothing, hat and sunglasses, shade and sunscreen. WHO encourages dissemination channels such as the media and tourism industry to publish the UVI forecast and promote sun protection messages. Secure .gov websites use HTTPS Because of modern westernized fashion and cultural habits, it is very common for people of all skin tones to dress in clothing that exposes larger portions of their skin to the sun in an attempt to achieve the perfect tan.
