Introduction

UV Index (Ultraviolet Index) is an international metric that quantifies the intensity of ultraviolet (UV) radiation reaching the Earth’s surface from the sun. Its primary purpose is to intuitively indicate the impact of UV radiation on human skin and eyes, standardized by organizations such as the World Health Organization (WHO) and the World Meteorological Organization (WMO). The numerical values typically range from 0 to 11 or higher, with higher values indicating stronger UV radiation and an increased risk of sunburn or health damage in a short period. This index is calculated based on meteorological observation data, solar altitude, ozone levels, cloud cover, and other factors, and is widely used as health risk information for the general public.

Applicable Scene

The UV Index is applied across a wide range of contexts, from daily life to specialized fields. In weather forecasts and meteorological apps, it serves as a reference for making UV protection decisions when going out, guiding actions such as using sunscreen, wearing hats and sunglasses, and adjusting outdoor activity durations. Additionally, in school education and public health sectors, it functions as an awareness-raising metric for UV radiation and health impacts, playing a vital role in preventing skin cancer and managing eye health. Furthermore, in agriculture, tourism, and sports industries, it is utilized as reference information for environmental risk assessments when planning work schedules or event operations.

Pros: The UV Index enables intuitive understanding of UV risks through a single numerical value, making it easily comprehensible for general users without specialized knowledge and facilitating international comparisons as a standardized scale. Moreover, its direct connection to health impacts makes it effective in promoting practical behavioral changes.

Cons: The UV Index assumes average human impacts and may not fully account for individual differences (e.g., skin type, age, medical history) or localized environmental conditions (e.g., highly reflective snow or water surfaces, high-altitude environments). Therefore, caution is needed as it may underestimate or overestimate actual risks.
