It is important to note that the UV index can vary depending on location, time of day, season, and weather conditions. Everyone should regularly check the UV index forecast for their area via weather websites or mobile apps. In addition, if you are fair-skinned, have a history of skin cancer or photosensitivity it is advisable to take even more precautions to protect your health.

General recommendations:

The WHO recommends the following protective measures against excessive exposure to ultraviolet radiation:

  • Limit the time of exposure to midday sun; shade will always be our best ally.
  • Wear protective clothing. For example, wide-brimmed hats will protect your eyes, face, ears, and neck.
  • Don’t forget to wear wraparound sunglasses that guarantee 99% to 100% protection against UVB and A rays;
  • Apply sunscreen to areas of skin that cannot be covered by clothing 20 minutes before sun exposure. Find out how to use sunscreen correctly.
  • Do not use artificial tanning devices, as they increase the risk of skin cancer. Artificial tanning should never be used to achieve a sufficient vitamin D level.

Recommendations for physical activity in the presence of UV rays:

  • Avoid activities between 10 a.m. and 3 p.m., when UV concentration is highest.
  • Wear light-coloured clothing.
