).

Part of the problem is the rise

of tanning salons, which according

to the

Daily Mail

, use powerful

ultraviolet (UV) rays (a primary cause

of melanoma, the most serious type

of skin cancer), and can be set hotter

than the Mediterranean sun.

Another report in the

Huffington

Post

, also looks at the new NICE

guidelines and highlights the

ongoing confusion around sun

cream strength, which many people

still find difficult to interpret (‘New

sunbathing advice: there’s“no safe

way to tan’’’—

). The report quotes the new

guidance, advising people to always

wear at least sun protection factor

(SPF)15 when in the sun and

clarifies that higher strengths of

sunscreen (such as SPF30) do not

necessarily mean you won’t burn.

MIXED SIGNALS

So, the best way to avoid the dangers

of sun exposure is to stay out of

the sun altogether, right? Well,

not exactly. As the NICE guidance

itself highlights, it is not as simple

as staying in the shadows, with

many adults in the UK experiencing

low levels of vitamin D, which is

particularly important for healthy

bones and teeth. The NICE guidance,

while stating that there is no safe

level of tanning, also recommends

limited exposure to sunlight to help

build vitamin D levels.

A suntan is a sign that your skin has been damaged by the ultraviolet

(UV) radiation present in sunlight (and which is reproduced by sunbeds),

and is trying to protect itself by making itself darker. This natural form of

protection is not adequate to prevent further UV damage, however, and the

darker the skin becomes, the more harm it has suffered.

Skin cancer is the most common form of cancer in the UK, and incidence

rates are rising. While the latest survey by the British Association of

Dermatologists (BAD) shows that the majority of the British public

are aware of the dangers posed by the sun, most do not take appropriate precautions to protect

themselves. Protective clothing such as long-sleeved t-shirts, wide-brimmed hats and sunglasses, is

the first line of defence against harmful UV rays. As is spending time in the shade during the hottest

part of the day, which is often between 11.00am and 3.00pm in the UK.

Sunscreen is an additional line of defence. A sunscreen with a sun protection factor (SPF) of at

least 30 and which also offers UVA protection should be applied liberally half an hour before going

into the sun, again just before leaving the house, and then again every two hours or straight after

any activity that may accidentally remove the protection, such as swimming or towel drying. As

most people do not apply enough sunscreen to achieve the advertised SPF, using a product with an

SPF of lower than 30 is not advisable.

Short exposures of the arms and face will help to maintain adequate vitamin D levels. If an

individual is concerned that they might be suffering from low levels of vitamin D they should visit

their GP. Amending the diet to include foods rich in vitamin D and taking vitamin D supplements

are safer alternatives to increasing vitamin D levels than unprotected exposure to the sun.

SKIN CARE MATTERS

i

As nurses, where does that leave

you? What advice should you give

patients on how to experience the

benefits of moderate sun exposure

while avoiding the dangers of skin

cancer? Luckily, the NICE guidance

makes a number of practical

recommendations that you can pass

on to patients:

`

To build up vitamin D, people

should expose their arms and legs

to the sun for short periods

`

Unfortunately there is no healthy

way to tan and any tanning

increases risk of skin cancer, even

so-called‘base tans’

`

People who should take

particular care in the sun,

include children, those with

fair-skin, people with extensive

moles or freckles and the

immunosuppressed (who may
