Reduce time in the sun between 10 a.m. and 4 p.m. If outdoors, seek shade and wear protective clothing, a wide-brimmed hat, and UV-blocking sunglasses. The time to burn can vary by skin type, but at a high UV level it is approximately 15 to 25 minutes. 8-10: Very High A UV Index reading 8 to 10 puts you at a very high risk of harm from unprotected sun exposure. UV radiation levels vary substantially with time and place. The increased risk of UV damage to the skin and eye during a holiday in a sunny location is often underestimated. The table below illustrates the changes in UV radiation levels with season and latitude. Maximal UV Index values are given for a range of cities in different countries UV Index . The UV Index provides a daily forecast of the expected risk of overexposure to the sun. The Index predicts UV intensity levels on a scale of 0 to 10+, where 0 indicates a minimal risk of overexposure and 10+ means a very high risk
A UV Index of 8 to 10 means a high risk of damage from unprotected sun exposure. You need to minimize sun exposure between the hours of the day. When outdoors, seek shade and wear protective clothing, a hat, and UV-blocking sunglasses.
21 Feb 2017 Created by the World Health Organisation, the UV Index (UVI) is a measure of the level of UV radiation in an area. The values range from zero upwards, and the higher the UVI recorded, the greater the potential for damage to 27 Sep 2019 “The higher the UV index, the more powerful the UV rays are and the more likely our skin is to get sunburned.” To find this metric in the wearable, search for a new watch face under the Face Gallery tab of the Watch app and 9 Dec 2015 To some extent, the moderate to very high labels tell us little except that UV intensity is increasing.

UV radiation levels vary substantially with time and place. The increased risk of UV damage to the skin and eye during a holiday in a sunny location is often underestimated. The table below illustrates the changes in UV radiation levels with season and latitude. Maximal UV Index values are given for a range of cities in different countries UV Index . The UV Index provides a daily forecast of the expected risk of overexposure to the sun. The Index predicts UV intensity levels on a scale of 0 to 10+, where 0 indicates a minimal risk of overexposure and 10+ means a very high risk In reporting the UVI, most emphasis is placed on the maximum UV level on a given day. This occurs during the four-hour period around solar noon. Depending on geographical location and whether daylight saving time is applied, solar noon takes place between noon and 2 p.m. A UV Index of 8 to 10 means a high risk of damage from unprotected sun exposure. You need to minimize sun exposure between the hours of the day. When outdoors, seek shade and wear protective clothing, a hat, and UV-blocking sunglasses. According to Duffey, you can get sunburned in the winter because snow can reflect UV and thus can lead to a higher UV Index. Also, it's important to protect your eyes on a high UV Index day.

Developed by doctors in 1987, it accounts for the way high-energy UV (UVB) affects us differently from low-energy UV (UVA). 22 Feb 2018 The UV Index - an international standard measurement of the level of UV radiation exposure - ranges from 0 to 11+ Extra protection against sunburn is needed when the value hits "very high" levels of between 8 and 10, and 18 Apr 2016 The UV Index indicates the degree of risk of sunburn and runs from 1-20. The highest level recorded in the UK is usually 8, but only in Southern England. In sunnier climates, the UV Index may be much higher than
30 Oct 2018 The UV Index was developed to help Canadians protect themselves from the sun's damaging UV (ultraviolet) rays. The higher the UV Index, the stronger the sun's rays, and the greater the need to take sun safety precautions.
