This question keeps coming back to us. And it is also close. The answer is simple:
No, sun-a-wear cannot prevent sunburn. You can prevent sunburns.
The reason for this answer is that we don't want to give people a false sense of security. sun-a-wear is a tool, a helper. Of course we are happy if we help as many people as possible to prevent sunburns. But as with any tool, how you use it ultimately matters.
You can set your UV dose limit in the sun-a-wear app. We know that many people put these in their sunburn dose range. The notification when the limit is reached and the UV protection measures recommended by the app help you not to exceed this limit.
In our tests, some of the users deliberately lowered their dose limit because they not only want to prevent sunburn, but also want to reduce their UV exposure in general. Still others have the goal of not exceeding a certain minimum number of sunbeams in the long term.
No matter how you use sun-a-wear, remember the following:
- If you don't wear the sensor where your body gets the most sun, it will measure a lower UV dose than actually reaches your skin. Of course, the app tries to use clever calculations to recognize if this should only be the case for a short time. But if, for example, your head is constantly in direct sunlight and the sensor is always in the shade, sun-a-wear cannot function properly.
- Even if you don't get sunburned, UV radiation can still cause permanent damage to the skin.
- Technology is never perfect. It can happen that the sensor or the app malfunctions. So never rely solely on sun-a-wear.
- The UV protection recommendations are derived from the general recommendations of the health authorities. But it may be that these are too strict or too lax for you. Ultimately you have to judge that for yourself.
