People visiting these islands could be at risk of high UV levels

People have been urged to take certain precautions as the ultraviolet radiation risk at a popular holiday destination area has been raised to “extreme”. Health officials in the Canary Islands have elevated the UV risk across several of the islands.

According to the Canary Islands Health Department, UV radiation levels are presently classified as “very high” across all islands. And Fuerteventura, Lanzarote and Gran Canaria have reached the highest “extreme” warning category.

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. Health experts also caution that UV exposure can suppress the immune system and even trigger the reactivation of viruses such as cold sores.

The alert particularly impacts those who spend lengthy periods outdoors, whether for work or leisure, as well as individuals with fair skin, light eyes or a family history of skin cancer. Children and older adults are also regarded as especially at risk.

As reported by Canarian Weekly on May 21, health authorities are strongly advising people to avoid direct sunlight between 11am and 5pm wherever possible, seek out shaded areas and wear protective clothing, wide-brimmed hats and approved sunglasses with UVA and UVB protection. The application of SPF 50 sunscreen is highly recommended, even on overcast days.

Authorities also issued a reminder to 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 across Spain throughout the year, owing to their geographical position and climate.

How to apply sunscreen

The NHS warns that most people do not apply enough sunscreen. As a guide, adults should aim to apply around six to eight teaspoons of sunscreen if you’re covering your entire body.

If sunscreen is applied “too thinly”, the amount of protection it gives is reduced. If you plan to be out in the sun long enough to risk burning, sunscreen needs to be applied twice:

• 30 minutes before going out
• Just before going out

Sunscreen should be applied to all exposed skin, including the face, neck and ears, and head if you have thinning or no hair, but a wide-brimmed hat is better. Sunscreen needs to be reapplied liberally and frequently, and according to the manufacturer’s instructions.

This includes applying it straight after you have been in water, even if it’s “water resistant”, and after towel drying, sweating or when it may have rubbed off. It’s also recommended to reapply sunscreen every two hours, as the sun can dry it off your skin.

Further to this, the NHS recommends you should do the following to stay safe in the sun:

• 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 – make sure to use enough and re-apply frequently
