The UV index (UVI) is an international standard measurement of the strength of sunburn-producing ultraviolet (UV) radiation at a specific location and time. It provides valuable information to help individuals protect themselves from sun exposure. Let me break it down for you:

1. What is the UV index?

   • The UVI measures the level of UV radiation.
   • Values of the index range from zero upward.
   • The higher the UVI, the greater the potential for damage to the skin and eyes.
   • Excessive UV radiation exposure can lead to skin cancer, especially in fair-skinned populations.
   • The UVI serves as an important tool to raise public awareness about the risks of UV radiation and the need for protective measures¹.

2. How is the UV index calculated?

   • The UVI varies throughout the day.
   • The maximum daily UV level, occurring around solar noon (between noon and 2 p.m.), is reported.
   • In some countries, sun protection times are issued when UV levels are forecast to be 3 or higher.
   • At these levels, there is an increased risk of skin damage, and protective measures are recommended¹.

3. Recommended Sun Protection Actions Based on UV Index:

   • UV index 0 to 2: You can safely enjoy being outside.
   • UV index 3 to 7: Seek shade during midday hours! Slip on a shirt, slop on sunscreen, and slap on a hat¹.

Remember to check the UV index for your location and adjust your sun protection accordingly! 😎🌞
