From the review, they found 2986 unique papers on the subject, they then assessed 91 papers from the 2986. From these 91, only 1 had a rigorous double blind testing but on only 46 people. The exposures for the light source was 2500 lux, IR light and no special treatment. The results were not significant.
So, lot-researched but maybe not well-enough researched.
- ekianjo 11y agoIn other words, the statistical power of such studies is so low, that it's like social science at best: a galore of false positive over true positive effects.
- bradleyjg 11y agoHow do you go about blinding a study which does or does not shine a bright light in subject's faces?
- MengerSponge 11y agoI'm guessing you vary the intensity and spectrum of the light. If the treatment doesn't show a dose-response curve of some kind, then it probably just doesn't work. Standard academic disclaimer applies: This isn't my field of study, and I'm sure there are many subtle mistakes in what I just said.
- tacos 11y agoA quick Google confirms this: they use either an identical-looking light with a different response, or a different light altogether. "Here's a light, here's a sugar pill, log your mood please..." As silly as that all sounds, it's already a million times better than what this guy did. He took the "if a little is ineffective a LOT will be better" approach and built a damn lighthouse in his living room. And if the goal is a DIY project and a blog post, OF COURSE you'll feel better after "your treatment." It's approaching group therapy at that point. There's a lot of this crap on HN lately.
- anarazel 11y agoSo, it's crap that he's done something that made him feel better. Yea. It's not science. And yes, he very well might feel better just be because he did something he believes in. But I don't see why that warrants a response like yours.
- tacos 11y agoThe article is entitled "You need more lumens" so he's already confronting me. The first paragraph disparages all existing commercial products and states, matter-of-factly that his approach is the one true way. The second paragraph states "Clinical studies have found that bright light treats SAD effectively" which is also a stretch. The article contains no research or sources except for a single Wikipedia link. It contains much hubris, yet no author's name. It does however contain numerous affiliate links. The article warrants a response like mine because the article is bullshit.
- shiven 11y agoWell, do you need more lumens? No, seriously. Do you? If not, then what is your point? Are you a SAD researcher with training and experience working with SAD? Or are you a SAD sufferer or have first-hand experience with SAD? If the answer to those questions is no, then you are starting to sound no different from the arrogant ignoramuses who think people with depression should just "get over it". This is HN and regardless of the scientific soundness of the post, it is a nifty hack. I might even make it. And use the affiliate links to show my appreciation of the person who made and shared the project. What's wrong with that? Perhaps you should question your assumptions before calling bullshit. What else are you missing out on in life with such an attitude?
- choosername 11y agoSo, your passive agressive closing is not better than open confrontation, only that it's direct.
