Solution? Solar powered computers, or would that be seen as
playing into the hands of the ecology lobby?
Danger, Will Robinson....

It never ceases to amaze me, how they connect this to that or whatever. I'm sure they'll come back next year and say its more of this or that and discount the past research as it unfolds. -----Willy
They got it partly right ...
Rickets is due to vitamin d deficiency, vit d deficiency is becoming more common and sun exposure is part of the problem. I don't think video games per se are the problem. The problem is that the entire culture is becoming less active and more passive.
Is it safe yet?
Aussies enjoy the sun and practically dive into it. They have the most skin cancer out there, so they can allow they're kids to enjoy less sun. I can only image if some indoor time would be mandatory for them. Heck, why not load up the McD's with vitamins and say that's the way to fulfill the deficiency. -----Willy
Life is a good premise for a video game
Good grief...we already have a game called Life based with a goal of gaining wealth so why not one of retaining health? I remember another called "Oregon Trail" having to do with making proper survival choices while moving westward. I never got much further than the town line. Ok, so your PS3 will lead to vitamin D deficiency and you turn to beach volleyball instead only to find malignant melanoma awaits you later. You turn from red meat to chicken to keep your lipids under control only to find yourself growing anemic. The list goes on and on. Face it....we're in a game with the cards stacked against us right from birth. And we all get to that point of wondering..."if I had it all to do over again...." but no God Mode exists in this video game.
much further than the town line
i never got further than the local saloon
Good one...still laughing (-:
Dr. Bill, does sunscreen have an effect on vitamin D uptake? That thought hit me as I've seen a lot of advice on the media recommending that kids be slathered with a heavy SPF one when going outside to play in the sun.
Sunscreen may be part of the problem ...
Most people believe sunscreen does block formation of Vit D from sun exposure. Whether that has been solidly proved in a laboratory I don't know.
We find ourselves in a bind from a prevention perspective. The measures that protect against melanoma do appear to raise the risk of osteoporosis and, less commonly, rickets. Most of us probably need to take vit d supplements.
Skin color matters. I read somewhere that African American adolescents have rates of Vit D deficiency over 50% in the US. Dark pigment protects against sun damage in high intensity settings (eg: Equatorial locations) but there is a reason the people whose anscestors historically lived further North have lighter skin. Dark skin also blocks Vit D production.
Sunlight = Vitamin D, but if food
Here's the scale of what you have to eat to equal 10min. of sunshine.
Sun 10min= 6 1/2 lbs. of shiitake mushrooms or 150 egg yolks or 3 3/4 lbs. of farm fresh salmon or 30 serving of fortified cereal or 2 1/6 lbs. of sardines or 30 cups of fortified OJ
Strange to talk of rickets and found this in the AARP magazine 9-10/09 issue. Recommend 100o IU of Vit. D supplement if unable to do the real sun routine of 10-15min. several times during the week. -----Willy
Some people need even more than that
I have a few patients who have to take about 100,000 units of Vit D every week just to keep their levels in a good range Most of us don't need that much - but a lot of older women do need about 1200 units daily or more.
The sun room
Most solariums(sp) were in use in the early medical hospitals if for anything just to make you feel good. It was nice to feel the sun on your face. Now, the real medical fact its more than a feeling but a requirement it seems. Heck, it actually works. I know I feel better when I can look out the window if for anything else to do so and stretch the legs and see something other than the walls. -----Willy
Or maybe not ...
I'm sure the sun room feels nice, but I'm not sure that it helps with Vitamin D. IIRC, Vit D production requires UV light, which is substantially blocked by most window glass.
I'm sure that some kinds of glass behave differently regarding UV light transmission but I doubt that the old solariums were designed to admit much UV light and doing so would have been problematic anyway.
Here's a question
is morning and evening Sun safer then mid-day Sun because the radiation has to pass through the atmosphere more due of the Sun's AM/PM angle? Can morning/evening Sun bathers skip the Sun screen?
I don't know all the details ....
I'm told that there is less UV light in early AM or late PM BUT that doesn't mean you can safely tan during those times. Since the UV light that helps with Vit D is also the UV light that can burn you there is no safe tanning.
Here's the thinking
Kids enjoy video games so much they stay indoors more now then ever before. This in turn leads to less Sun exposure for them and this in turn leads to Rickets.
I did not put this here for the kids, by the way, I put it here for you Speakeasy folks and other who do PCs a lot, like myself. It is real I had this affliction several years ago. So, I do my vitamin D now. Myself, I believe it's more of a problem in Winter and it is Winter now.
