Vitamin D vs. skin cancer

Posted by andrea tomkins in: Misc. life

Never before have I noticed so many crazed sunscreen slathering mammas than I have these past few years. And last summer I spyed record amounts of children wearing UV-suits instead of traditional swimwear. I don’t have anything against them. They’re cute. And hey, it’s a good option if your wee one burns easily and doesn’t like you to apply sunscreen.

The problem is when people overdo it.

I used to be one of those sunscreen slatherers. I was slave to sunscreen. When the girls were wee I’d nab them before they dressed in the morning, squeeze a couple of shots of SPF45 into the palm of my hand and coat them with it from their head to their tender toots. Every. Darn. Day.

Now I don’t.

In fact, I stopped doing it a couple of years ago.

Reasons:

a) I was never entirely happy with the stuff I was coating them with. The skin is our largest organ. And it’s a giant sponge. I wasn’t convinced that sunscreens are completely free of potential carcinogens. Given the amount that I was using on a daily basis, I thought I should be better informed about what I was putting on their little bodies.

b) They weren’t getting sunburns. Why bother if the exposure is going to be minimal?

To clarify: I do put sunscreen on my kids when we’re at the beach or swimming in the pool or playing in the hot beating sun for many hours in one go. But I will not put sunscreen on them after 3 p.m. If they’re just playing outside or going to and from school I will put a bit on their cheeks and nose, a bit on their shoulders (if they’re exposed) and that’s it. 

I remember once we were all at an early-evening soccer practice. Some mom was vigorously layering sunscreen on her kid (um, the sun was setting) and then topped it off with a layer of bugspray (there were no bugs either!). Yeeuck.

It’s always been important to us that the girls get fresh air and unadulterated sunshine. After all, that’s how we evolved. Outside! Stalking animals and sleeping in caves! Outside, in the sun, is a natural place to be!

I previously had read that our body needs vitamin D, but I hadn’t realized exactly how much, and how important it is to our health. I’m sure you’ve heard by now, but if you haven’t you should read this Globe and Mail article.

“In June, U.S. researchers will announce the first direct link between cancer prevention and the sunshine vitamin. Their results are nothing short of astounding.

A four-year clinical trial involving 1,200 women found those taking the vitamin had about a 60-per-cent reduction in cancer incidence, compared with those who didn’t take it, a drop so large — twice the impact on cancer attributed to smoking — it almost looks like a typographical error.”

Only 10 – 15 minutes a day is necessary. The trick is to be reasonable about exposure to sun, as well as to sunscreen. There’s no point overdoing either of them. 

But I am seeing the sun in a whole new light now. Aren’t you? I would love to hear your take on the sunscreen debate.

I don’t “do” sunscreen. I’m not even sure if we have a current bottle here in the house. In the summer, we’re primarily out and about before 12pm and after 4pm–avoiding the worst of the midday rays. The thought of what is absorbed through the skin is what turned me off of it in the first place and then, after having the boys, it seemed important to me that they learn “safe sun” techniques instead of coating them in a greasy, stinky layer of avoidance.

The UV rays are only half of the reason we avoid being outside in the midafternoon, though–the other is the heat and smog. It’s much worse at those times of day and my country-raised lungs have just never been able to adapt to breathing in that thick Ottawa summer air.

I’m with you. Sunscreen is full of chemicals. My strategy is to apply sunscreen in the early part of the season since our skin is a blank slate after the winter. Once we’ve had a bit of exposure and our skin has “toughened” up then I go without the sunscreen if we’re just going for a walk or if it’s before 10 am or after 3 pm (sometimes I’ll put it on the cheecks, nose, etc). If we’re going to be out all day (like at a pool) then I liberally apply the sunscreen.
Yes, too much sun can cause cancer but everything in moderation, eh? We need sun exposure everyday. We now know that Vit D is necessary and there’s a school of thought that many diseases are caused because of a lack of Vit D.
This is an interesting discussion. To muddy the waters even more….how ’bout sunglasses? Is it true that sunglasses actually cause sunburns b/c they interfere with the eyes sending the message to the brain to protect itself from the sun?

I’ve come a long way, baby. In high school, I used to slather on baby oil and sit in the sun for hours. Now, I’m maybe a little bit more cautious than you. If we’ll be outside for a goodly portion of the morning (i.e. playing at the park and in the driveway, going on a picnic or a hike) I’ll put sunscreen on the exposed bits. But if they’re just going out to kill some time while we get ready to do something else, or it’s late in the afternoon, I won’t bother.

Myself, I’m fairly scrupulous (some might say addicted) to lip-balm sunscreen for my lips and nose. Can’t stand to have sunburned lips, and with my freckles and skin tone, it doesn’t hurt to be cautious. There is nothing more healing for my skin and my soul, though, than spending a morning with a cup of coffee and the newspaper or a good book, face angled up to catch the sun!

I am the same…I usually make sure their arms are covered and that they have hats. I also just got them some decent sunglasses too…but I try to go easy on the sunscreen unless we are out in full sun or at the beach, etc.

No sunburns for them yet.

I cannot stand sunscreen. There I said it. I used baby oil and iodine, heck I even used cooking oil a few times to get that golden look when I was younger. Although I no longer pull things out of the kitchen (except maybe lemon for my hair) I don’t overdo the sunscreen. I use it a bit more in the Spring and definately on the beach because I have experienced a few bad burns from forgettting at the beach. But otherwise I don’t do it.

I do, however, slather J. Not everyday and not from morning to night, but I make sure his face is taken care of even though he wears hats and his arms and legs (the area that pokes out from his swimsuit and swimshirt. J has very pale, almost translucent skin and the last thing I need a doctor telling me is that I didn’t take care of my kid and now he has severe burns from me not putting some sunscreen on. I think my Mom only used it on us at the beaches, but until J is a bit older to decide for himself, I will use it for him, just a little. And I only do it when we are out during prime times.

Oh yes, and no bug spray here, I don’t even have any in the house, except muskol that hubby keeps in his golf bag.

I have been slathering my kids with SPF 50 and I even have been known to use 70 if I have been able to get my hands on it.
Yikes.
My husband and I both easily burn and our children are very very fair. That said, neither of my kids have ever had tan lines because they are slathered in so much sunblock spring-fall.
I HAVE always said that I am concerned with what chemicals are in sunblock to a) ‘protect’ our skin from the harmful rays b) what is in them to keep them ‘water proof’ c) what is in them that causes my eyes to sting!!!
So yes my kids wear ALOT of block, but I also bath them when we come in from being outside (like they have several baths a day) to wash the block off, and simply because they get so filthy playing in the dirt and I don’t want them crawling into their bed at naptime dirty!
I was suprised to read the comments that others aren’t using sunblock as much as I am.
I seem to be a total freak!
Something to consider…if you get any info on this subject pls share!!

Apparently a big issue with sunscreens is the chemical (the name of which escapes me know) that is used to make it smoother/easier to spread. Someone once recommended that spray sunscreen is better because it doesn’t contain this stuff whateveritis.

Also: re: sunglasses. I hadn’t heard anything like that VV. I haven’t actually been wearing mine very much.

Over the winter I spent a lot of time in front of my Litebook due to seasonal S.A.D.

The whole point of using the lamp is to improve your mood, it’s only effective if you point the lamp (which is kind of like a spotlight) at your face so it goes in your eyes. I researched it a little because I was wondering about the angle of light and whether or not it was enough that the light was on my face. It has to go in your eyes. Along the way I read that there is an issue with sunglasses and people who suffer from S.A.D. The sunglasses prevent from light getting in the eyes, and it’s that light that boosts melatonin levels and improves mood/energy and all of that.

SO. Because of this I’ve cut down on the amount I wear my sunglasses. Funny, a few years ago when I was wearing them on a daily basis I found that I almost HAD to wear them everyday, because I’d developed a sensitivity to bright sunlight. I could barely function without them. And now that I haven’t been wearing them I can get by.

Just please don’t ask me about the wrinkles that are forming around my eyes as I squint. But the way I see it, getting a proper does of light is good for my mental health and I should stop being so vain. :)

“If increasing numbers of us are getting skin cancer – it has risen threefold in the past 20 years – while too few of us are using sunscreens, you’d think part of the public health mission would be to persuade even more of us to slather on even greater quantities of those sun protection factors (SPFs). But here’s the curious thing: skin cancer rates and sunscreen use have both been rising simultaneously. ”

From this article about sunscreens published in the Guardian.

I used to slather Miranda but when Nathan came along I Did when he wa a baby but not so much anymore. I use Moskol on Nathan’s CLothes and hat when he is outside BUT NEVER ON HIS SKIN. He swells tooo much not to put some on him plus we live in the boonies so lots of Bi bits.

As for myself I am not a bif sun worshiper. I don’t tan well and I burn easy but I try to keep out of it the worst part of the day. My legs are lily white all year long.

Burt’s Bees makes a good sunscreen (and bugspray) and, if you desired, you could eat the stuff!
