Ryofire Posted November 8, 2009 Share Posted November 8, 2009 I mentioned something earlier about light therapy and how it could help seasonal affective disorder. I was considering purchasing a 10,000 lux light box. However I still have one question to ask. Do these light boxes produce UV radiaton? And when I use them should I put something with a minimum of SPF 15 on? Link to comment Share on other sites More sharing options...
cubby2112 Posted November 8, 2009 Share Posted November 8, 2009 Most have UV filters I think. Check into that in the description of the one you are buying. Link to comment Share on other sites More sharing options...
Ryofire Posted November 8, 2009 Author Share Posted November 8, 2009 What exactly do you mean by UV filters? Link to comment Share on other sites More sharing options...
cubby2112 Posted November 8, 2009 Share Posted November 8, 2009 They have some sort of screen that keeps the UV rays in, so they don't get into your eyes or damage your skin. Link to comment Share on other sites More sharing options...
Fallen_Horse Posted November 9, 2009 Share Posted November 9, 2009 I am curious as to how this is different than simply being in a lit room? Link to comment Share on other sites More sharing options...
cubby2112 Posted November 10, 2009 Share Posted November 10, 2009 A lit room isn't bright enough to incite a substantial amount of melatonin production. These types of lights are extremely bright, like daylight. You can get the same effect from a sunny day, but those are not always available/convenient.

Marcina Posted November 10, 2009 Share Posted November 10, 2009 Especially in the fall/winter. It's been raining for about a week now, and for the past few days it's been windy, even hailing at times. It gets dark at 5pm. It's starting to affect my mood too. I've become a total bitch.

chrisjs Posted November 10, 2009 Share Posted November 10, 2009 I believe the light spectrum is tuned as well, no? Link to comment Share on other sites More sharing options...
cubby2112 Posted November 11, 2009 Share Posted November 11, 2009 I believe the light spectrum is tuned as well, no? What do you mean by 'tuned?' The intensity of the spectrum? Or the types of light within the spectrum? Link to comment Share on other sites More sharing options...
beforewisdom Posted November 11, 2009 Share Posted November 11, 2009 Fromhttp://jacknorrisrd.com/?p=664 During the dead of winter, I have a vitamin D lamp that I sit in front of for about 10 minutes a day. Vitamin D2 supplements should be fine – I don’t think every vegan needs to run out and get a vitamin D lamp for the winter. I tend to suffer from (self-diagnosed) seasonal affective disorder, so I like the lamp. Until a year ago, I was living in Sacramento where there was plenty of sun throughout the year, but now that I live in Oakland, which can be a lot more cloudy, I have found that I need more light during the winter.

Yeah, I think most are tuned to keep the harmful UV rays rather low, but the good ones (UVB I think, not sure) at a decent level. Thanks for the link to Jack Norris, Beforewisdom. Nice to know that he supports them. Link to comment Share on other sites More sharing options...
