Health authorities have issued an urgent warning as the ultraviolet radiation risk in parts of the Canary Islands has been raised to 'extreme'. The Canary Islands Health Department has classified UV levels as 'very high' across all islands, with Fuerteventura, Lanzarote, and Gran Canaria reaching the highest 'extreme' category.
Health Risks of UV Exposure
Prolonged exposure to ultraviolet radiation can lead to serious health complications, including DNA damage, severe sunburn, allergic skin reactions, eye conditions, and a heightened risk of skin cancer, including melanoma. Experts also warn that UV exposure can suppress the immune system and trigger the reactivation of viruses such as cold sores.
Who Is Most at Risk?
The alert particularly affects those who spend long periods outdoors for work or leisure, individuals with fair skin, light eyes, or a family history of skin cancer. Children and older adults are also considered especially vulnerable.
Official Recommendations
As reported by Canarian Weekly on May 21, health authorities strongly advise avoiding direct sunlight between 11am and 5pm, seeking shade, and wearing protective clothing, wide-brimmed hats, and sunglasses with UVA and UVB protection. The use of SPF 50 sunscreen is highly recommended, even on overcast days.
Authorities also reminded parents that babies under one year old should never be exposed directly to sunlight, as their skin is particularly sensitive and incompatible with most sun creams. The Canary Islands consistently record some of the highest UV radiation levels in Spain due to their geographical position and climate.
How to Apply Sunscreen Properly
The NHS warns that most people do not apply enough sunscreen. Adults should aim to use around six to eight teaspoons for full-body coverage. If applied too thinly, protection is reduced. Sunscreen should be applied twice: 30 minutes before going out and just before exposure. It should be reapplied liberally and frequently, especially after swimming, towel drying, or sweating. Reapply every two hours as the sun can dry it off the skin.
Additional Sun Safety Tips
- Spend time in the shade between 11am and 3pm
- Never burn
- Cover up with suitable clothing and sunglasses
- Take extra care with children
- Keep babies under six months out of direct sunlight
- Use at least factor 30 sunscreen – ensure enough is used and reapply frequently
