Knowing when you or your kids have had too much sun is no easy task especially when you are a parent with so many other things to remember and keep track of. With no practical way to measure ultraviolet rays, it's difficult to know how much sunscreen to use, when to reapply it, or when to get out of the sun. SunSignals provide a visual cue and take away the guesswork of knowing when you and your children are reaching a "danger zone" of UVB radiation, before realizing harmful sunburn. Time of day, time of year, altitude, cloud cover, and the angle of the sun all affect the intensity of the sun's rays. SunSignals are fun, easy to use, inexpensive and provide an easy way to tell when you've had enough sun.
