SmartSun UV-wristband – will it save
you from sunburns?
I am sure you know that it is good and healthy to be in the
sun but it is bad and maybe even can be dangerous to get a
sunburn.
The advice to get out of the sun before you get a sunburn is
a good one to follow. However, the problem is that
normally you don’t know that you have had enough sun-
exposure until it is too late and you already have got a
sunburn that will be painfully noticeable the day after.
The SmartSun UV-wristband
solves this problem by displaying a
warning that you have had enough sun
BEFORE you get a sunburn.
I also believe this could be the perfect
solution to measure when you have
reached the peak of optimal vitamin D
generation.
The SmartSun UV-wristband is a brand new invention by
Claes Lindahl, a Swedish inventor and researchers at the
University of Strathclyde in Scotland has developed the
wristband.
Briefly described, Smartsun is a dosimeter measuring the
accumulated exposure to UVA and UVB during a day.

2. wristband gives the indication when you will need to
protect yourself from the sun.
If you decide to use sunscreen, you should apply the
sunscreen also to the surface if the wristband.
In principle you can say that the SmartSun wristband
mimics the reaction of ultraviolet light in your skin.
On the webpage of SmartSun, it is mentioned that the
wristband is especially designed for people with skin-type
1 and 2.
I believe it is a mistake (actually made possible by a
slightly localized definition of the Fitzpatrick skin-type
scale by the Swedish Radiation Authority) to group people
of those skin-types together. They have totally different
characteristics since by definition (at least by the original)
people with skin-type 1 will never develop a tan (they do
not have the “right” kind of melanin for that). People with
skin-type 2, on the other hand (and I know since I am a
skin-type 2 myself), can develop a nice tan if gradually
exposed to UVB.
Anyhow, people with the original Fitzpatrick skin-type 1,
are extremely rare and should never be in the sun for
more than a couple of minutes. So let’s say that the
SmartSun wristband is useful mainly for people of skin-
type 2.
At least in theory, the SmartSun wristband sounds like the
perfect tool for vitamin D tanning.
The question is, will the SmartSun UV-
wristband work also in a sunbed?
Having studied the description, my answer is both yes, and
no. Since it measures both UVA and UVB, it will still be
important to know how much UVB there is in the sunbed
you use in order to get your vitamin D. The other problem
might be that the color-change is probably not visible
through tanning-goggles.
In general, I believe it would have been much better to

3. make the SmartSun wristband indicative mainly of UVB
and less, if at all, of UVA. That would give a more accurate
burn-indication as well as a signal of enough vitamin D.
Here is the description of how SmartSun works:
The Smartsun wristband is:
For 1-day use. At the end of each day, remove the
sensor and throw it away, even if the color has not
changed. Always use a new sensor each day.
Can be used in water – even chlorinated water and salt
water.
Detects both UVA and UVB.
Can be used in combination with sunscreen by
applying sunscreen to your body and to the wristband.
The wristband is functional with any type of
sunscreen.
You can use the wristband all day, even if you go inside
for awhile.
Smartsun wristband is specifically developed for people
with sensitive and very sensitive skin.

say that for vitamin D tanning, you should
