Due to an increasingly greater awareness of the dangers of skin cancer, people are adding sunscreen application to their daily routines. That’s fantastic, but it’s also important to remember that that initial use is not a one and done procedure. In fact, spending a good deal of time outdoors on the strength of a single coating of sunblock is almost as bad as not using it at all. All of this then begs the question, how often should you apply sunscreen?
Applying Sunscreen Correctly
Unfortunately, there is no one size fits all answer to that query. So it’s vital for people to understand what factors determine the speed at which a sunblock loses its’ effectiveness.
As you might guess, some of this is common sense. But sometimes people are fully aware that it’s time to add more, yet instead (perhaps subconsciously) play a similar game to the one in which drivers see that their yellow gas light is on, but bypass a fueling station anyway thinking they can make it to the next one unscathed. The sun’s harmful UV rays are nothing to take chances with, though; those who do risk everything.
So what impacts the efficiency of your sunscreen?
Well for starters, water. Any type of freshwater, saltwater or chlorinated-water swimming will escalate sunblock erosion. Same thing if you or your children are running through lawn sprinklers. Or even just walking outside in the rain.
Sweating caused by heat, humidity, physical exertion or any other means will also shorten its practical lifespan. As will the level of the sunblock’s SPF, so make sure to read the bottle carefully to ensure you’re buying the product that best suits your needs.
Staying outside during the sun’s peak hours of 10a.m. and 4p.m. is not a good idea, regardless. But if you have to, you should not only be frequently re-applying sunscreen, but also spending as much of that time as possible under natural or artificial shade.
Many people associate sunburns with skin cancer and Melanoma, as they certainly should. But it should also be noted that there are many other forms of sun skin damage that UV rays can cause, as well. Among them are prematurely-aged skin, wrinkles and sunspots; which nobody wants to deal with. The thing is that sooner or later, one way or another, time spent outside unprotected against the sun will come back to haunt us. It’s virtually unavoidable.
One easy way to know precisely when to re-apply sunscreen is to use our Sundicators UV monitoring wristbands. Through their color-changing technology, a wearer can tell with a simple glance at his or her wrist when more sunblock is needed. And, eventually, when it’s time to get out of the sun entirely. Sundicators are waterproof, unisex wristbands that can be used by all ages. They’re as lightweight as a bookmark, and they don’t interfere with any outdoor sport or activity.
However it is that you choose to remind yourself about sunscreen re-application, please just make sure for your own good that something does.
