Out in the sun
Here comes, or there goes, the sunscreen?
DEAR Mr Dad: I thought I was doing the right thing by slathering my oneyear-old with sunscreen when we go outside, but I just read that the chemicals in sunscreen could be more harmful than the sun. Now, what are we supposed to do?
Before we get to the actual ingredients of sunscreen, let’s talk about the vocabulary, which can often be contradictory, confusing, or both.
In June 2011, the US Food And Drug Administration tried to deal with this issue by coming up with new regulations for sunscreen labelling, including requiring a “drug facts” box, forbidding claims such as “sunblock” or “waterproof”, and clarifying which products can be labelled “broad spectrum” (meaning that they protect against both UVB and the more deadly UVA rays). Unfortunately, these requirements don’t go into effect until summer 2012.
Okay, back to ingredients. In a 2010 study, the US Environmental Working Group, a nonprofit watchdog, reported that only 39 of the 500 sunscreen products they examined were safe and effective.
The study claims sunscreens flaunt false sun protection (SPF) ratings, that one commonly used ingredient, oxybenzone, is a hormone-disrupting chemical that can affect puberty, and another, retinyl palmitate (a derivative of vitamin A), could actually accelerate some cancers instead of preventing them. But the emphasis needs to be on the word “could” as the research is hardly definitive.
The American Academy Of Dermatology, for example, maintains that sunscreens – even those with oxybenzone and retinyl palmitate – are safe for most people over the age of six months.
The American Academy Of Pediatrics (AAP) agrees, but recommends that babies under six months be kept out of direct sunlight and shouldn’t wear sunscreen except in very small areas, such as their hands.
For babies over six months, the AAP recommends sunscreen but says the best protection is limiting sun exposure – especially around midday – and wearing protective clothing, including a hat.
If you’re concerned about sunscreen chemicals, look for “chemical-free” or “mineralbased” brands that don’t contain oxybenzone.
These mainly use zinc oxide or titanium dioxide as the active ingredient, both of which form an actual barrier on the skin without being absorbed and start working immediately upon application.
But don’t go overboard. In small doses, the sun is actually healthy. Those UVB rays help our bodies produce vitamin D which is essential for healthy immune systems and bones. If you’re going to be out in the sun for a few hours, you and your children need protection; if you’re just running around for 10 minutes, you should be okay (but check with your paediatrician to be sure).
Here’s how to protect babies and toddlers from the sun:
> Limit exposure to direct sunlight, especially when rays are strongest.
> Use protective lightweight clothing to cover up, including a wide-brimmed hat and sunglasses (if they pull them off, keep putting them back on).
> If you’re not using zinc or titanium blocks, apply sunscreen 30 minutes before going outside so it has plenty of time to get absorbed into the skin. But regardless of the type of sunscreen, reapply every two hours or after swimming (no sunscreen is completely waterproof). > Don’t fear the sun. A little every day is good for you. – McClatchy-Tribune Information Services n Armin Brott is the author of TheMilitary Father:AHands-OnGuideForDeployed Dads and TheExpectantFather:Facts,Tips, AndAdviceForDads-To-Be.
