Vitamin D/Sunlamp

[Guest guest]

I feel that much of the progress I made over the summer is at least

partly attributable to greater sun exposure. With winter fast

approaching, I'd like to be pro-active this year. I am thinking of

getting one of those Sperti Sentosa lamps. It apparently emits 73%

UVA & 27% UVB. Now when I read about sun rays on Wikipedia, it says

" The Sun emits ultraviolet radiation in the UVA, UVB, and UVC bands,

but because of absorption in the atmosphere's ozone layer, 98.7% of

the ultraviolet radiation that reaches the Earth's surface is UVA. "

Apparently, it's the UVB that's largely responsible for tanning &

burning. I see that tanning beds emit anywhere from .8% to 10% UVB.

I'm not about to spring for a tanning bed but wonder if visits to a

tanning place might not be better than actually buying and using a

Sperti lamp. Any information/input would be appreciated.

Thanks,
