A Little Background on UVB Rays
Before we begin, let’s review a little background information. Ultraviolet (UV) radiation is part of the electromagnetic spectrum emitted by the sun and for convenience, it is divided into three bands, UV A, B and C. Both UVA and UVB are of major importance to human health. Small amounts of UV are essential for the production of vitamin D in people, yet overexposure may result in acute and chronic health effects on the skin, eye and immune system. In general it is the UVA and UVB range which is responsible for sunburn.
How It Works
SunSignals® Sensors uses a patented technology to detect and react to UVA and UVB radiation. The Sensor is composed of radiation-sensitive chemicals that respond to changes in UVA and UVB radiation by changing color. During low UV exposure, the Sensor stays a light orange. As UVA and UVB radiation exposure increases, the color changes to a dark orange and the sun designs disappear. This tells you that it is time to apply more sunscreen, put on protective clothing, or seek shade.
How To Use
SunSignals® Sensors are self-adhesive and water-resistant stickers. Apply one sticker anywhere exposed to the sun, like your arm, shoulder, hat, shirt or other clothing. For the best results, always make sure that the area you are applying it to is dry. Do not rub sunscreen on the Sensor surface. When the Sensor turns deep orange, it’s time to take action. Apply more sunscreen, put on protective clothing, or seek shade. If you apply more sunscreen, be sure to put on a fresh SunSignals® Sensors!
Why It’s Important To Use SunSignals® Sensors
Sunscreen and protective clothing help protect your skin from UVA and UVB rays, but it’s important to remember that the amount of sun exposure depends upon a number of factors including the length of exposure, time of day, geographic location, weather conditions, pirspiration , activity and swimming which will wash off some of the sunscreen. Luckily, SunSignals® Sensors are waterproof and they can even be applied to the skin before the sunscreen is applied. This way it removes all of the guess work as far as UV Dose is concerned. If swimming removes some sunscreen from the skin, it will also remove it from the sensor thereby you will always get a true indication when the skin in danger of getting a burn and it is either time to apply more sunscreen or time to cover up. That’s the advantage of SunSignals® Sensors — it will immediately tell you when you’ve become overexposure BEFORE harmful sunburns occur.
