Quickie: The bracelet that tracks your sun exposure

So you’ve applied your sunscreen dutifully. Great! But what if it wears off? How will you know before it’s too late? Now there’s a way to tell: the UVSunSense bracelet:

Developed by a nuclear physicist, the UVSunSense wristband technology is similar in principle to monitoring devices used for personnel at nuclear power plants or in jobs dealing with nuclear medicine. But instead of measuring gamma rays, UVSunSense is calibrated for ultraviolet – or UV – radiation present in sunlight. The band’s four color stages indicate changing conditions and how a user should adapt to the sunlight. The wristband is orange when removed from the packaging. It becomes purple when exposed to the sun, indicating that it has been activated. When it transitions to a dark brown the wearer needs to immediately reapply their protective sunscreen. If the band turns a salmon color, the wearer should get out of the sun completely, having approached the recommended daily limit of UV radiation. Further exposure will likely result in painful sunburn and increase the risk of sun poisoning, also known as photodermatitis.

Here’s a diagram to illustrate the color changes:

The UVSunSense band is available in packs of 7 for $6.85 (plus shipping) at Amazon. Or you can check out the “Where To Buy” link on the UVSunSense website (linked above) for local retailers.
