There's a great deal of debate among researchers about the best light therapy for SAD (seasonal affective disorder).
I'm going to narrow the research findings down as much as possible for you. That way, you'll have the basic information you need to know for purchasing a light box for SAD. And you won't be overwhelmed with all the research from the science journals.
Let me first say, I don't take any of this lightly (no pun intended). Depression is a serious topic, one that has greatly affected my own family. (Two first cousins—one was my best friend—committed suicide, and two other family members attempted suicide several times and almost succeeded.)
Without question, light relief therapy is a highly effective method for overcoming the seasonal depression that occurs in the fall and winter months.
Over the past several years, the standard recommendation for the best light therapy was for light boxes containing fluorescent bulbs that put out a white light. White light does work and is designed to mimic the effects of natural daylight.
But some of the claims for these lights sometimes refer to them as “full spectrum lights.” And they also claim they are the "best light therapy."
Here's what Dr. Daniel Kripke, an expert on sleep, sleep medications, and bright light therapy has to say about full spectrum lights:
“A lot has been written about natural lighting and whether one should use lighting with a "full" spectrum. I suspect this spectrum of claims is largely baloney! I doubt that any of the commercial sources really produces a light spectrum which could be mistaken for the rather smooth spectrum of natural sunlight.”
Light comes in colors, as you've seen if you've ever viewed a prism. For the purposes of seasonal affective disorder light therapy, the colors of interest are white, blue, green, red.
Forget about red for seasonal affective disorder light therapy. White and blue are better for SAD.
Green light therapy is an interesting, fairly recent development in light therapy for SAD over the past 10 years or so. However, I haven't seen any substantial evidence that green light is better than blue light (and green light boxes are far more expensive).
What I have seen is that green light has been touted as being safer for the eyes than blue light.
The thought is that light causes macular degeneration in the eyes. So over a lifetime of exposure to the sun, there is potential damage to the retina of the eyes.
Light boxes are designed to put out a certain amount of light intensity, known as lux. The thinking is, sitting in front of a light box may lead to macular degeneration. And some discussion has speculated that blue light is worse than green light or white light.
I'm not convinced of this.
Here's the thing.
All you have to do is keep this in mind: DO NOT stare into any light box! You don't stare directly at the sun and you should never stare into a light therapy box.
Also keep in mind that white light does contain a lot of blue light and blue-green light.
The standard advice when dealing with white lights is “get a light box with 10,000 lux.” For a white light therapy lamp, that's good advice.
However, new light therapy research shows that blue-enriched light, which has a lower intensity, may be just as effective as the high intensity white light boxes.
I know I know. All of this sounds confusing and you're sitting there thinking, “What the heck am I supposed to buy for the best light therapy!”
For now, I think your best bet is to go with either a white box or the new smaller blue light boxes. Green light therapy is expensive right now and I'm not convinced the potential benefit is worth the price.
If you have any eye disorders, such as glaucoma, cataracts, or susceptibility to macular degeneration, don't use a light box without consulting an eye doctor. If you don't have eye concerns, light boxes for SAD should be safe.
I think it's far better to try something in the way of light therapy for depression, even if all the facts about different types of lighting are not known.
It's clear that whether blue light is better than green light is better than white light as the best light therapy still needs more research to determine.
In the meantime however, just do something about your seasonal depression!
The people who get somewhere in this world are the ones who take action, even in the face of depression and setbacks.
So don't let confusion stop you from getting help that is available.
There are companies all over the Internet that sell light boxes for SAD. You can spend hours searching around (as I have).
If you want to save yourself some time, I think the easiest thing to do is start by clicking below to view one of the Philips blue lights from Amazon.com.
Verilux is also an excellent light box company. The box below uses white light therapy.
And last but not least, you may find a light visor to be convenient. Put it on your head and you can move around. BioBrite has been around for over 20 years.
At Amazon, you can see the reviews and how well people have been helped. Maybe these products will work for you too.
Please make sure whatever light therapy equipment you choose can be shipped to your country.
The best light therapy and seasonal depression treatment is the one that works for you. That could mean a combination of therapies:
The key is—try something until it works to boost your mood and gives you vibrant fall and winter energy. And always keep in mind that the best light therapy is to get as much sunshine as possible. I truly wish you all the best!
