Blue Light Therapy for Depression
Do you dread the onset of winter?Have you noticed a pattern of decreased energy and lethargy that drags through the winter and lifts each spring?
Light therapy has been shown to be an effective treatment for depression related Seasonal Affective Disorder. For those looking for the best light therapy devices we have two models built by goLite. These handy lightweight lamps are easily transportable making them convenient for busy lives.
GoLite P1 and GoLite P2 are the latest evolution in light therapy with patented BLUEWAVE™ technology. goLite lamps deliver 100% of the effective bandwidth of light that is believed to be responsible for causing the antidepressant response in Seasonal Affective Disorder and circadian related disorders.
Check with your health care practitioner to see if you are a candidate for light therapy.
Light Therapy by GoLite

Although the goLite is only 6" X 6" in size, it produces more of the effective bandwidth than most full-size lightboxes. In addition to effectiveness, the GoLite's greatest advantage is its compact size — it can go anywhere & be used anytime light is needed.
BLUEWAVE™ technology is so effective that it has been used at NASA to regulate astronaut's and shuttle crews' sleep/wake schedules. BLUEWAVE was also recently recognized at the Society for Research in Biological Rhythms (SRBR) as the most efficient technology for regulating circadian rhythms.
Who Buys This Product?
The GoLite is perfect for those who need effective light therapy but have little time to sit in front of a conventional lightbox. Many light therapy users prefer the GoLite's portability because they benefit from their light more than once during the day, and they can take the GoLite anywhere.
How to use your GoLite:
You usually only need to use your GoLITE once a day for about 10-15minutes. Most people get better results when they use their light inthe morning but different times during the day may work best for you. You can also use your GoLite anytime you need a burst of energy.Two Models to Choose From:

P2 has everything that the P1 has. The main difference is that P2 is cordless and therefore easy to transport (i.e. to the gym, to your desk at work, or to your work shop etc.)

The goLite™ P2 has the same specifications as P1 plus these features:
* Cordless operation
* 2 hour quick charge allows 4 sessions
* Full charge allows up to 6 sessions
* Works with adapter or on battery charge
* Clock timer with treatment reminder alarm
* Battery indicator

There are many reasons for developing the symptoms that mimic seasonal
depression. You are encouraged to meet with your health practitioner to determine if you are a good candidate for light therapy.
There is a decade of research that supports light therapy as a viable solution for seasonal affective disorder. The International Seasonal Affective DisordersAssociation has been quoted as saying:
"Light therapy has been shown to be effective in up to 85% of diagnosed cases."

The discovery that low intensity blue light (470 nm) is superior to white light at regulating melatonin and circadian rhythms has caused a firestorm of interest and debate.The fact sheet below was prepared by the folks at Apollo, manufacturers of BLUEWAVE® Technology the main component of GoLites. Scroll down to find the references cited.
Note: Blue is 2 X more effective: Blue light alone is twice as effective as 10,000 lux at suppressing melatonin and twice as effective at shifting circadian rhythms. 1,2
Note: The circadian response (SAD, sleep depression, etc.) is through melanopsin photoreceptors in the eye, and melanopsin responds to 470 nm light, not white light. 3,4,5,
Note: All white light devices produce blue light, which is why they work. 7,8
Note: BLUEWAVE® isolates only the effective portion of blue light already present in 10,000 lux. 9
Note: All 10,000 lux light boxes produce at least 50% more blue than is necessary, and most produce 3 – 5 times the necessary amount of blue light. 10
Note: All 10,000 lux light boxes produce significant peaks of near UV light (405 nm and/or 430 nm). Some lightboxes also produce significant amounts of UV light. 11
Note: Noonday sunlight produces over 20 times more blue light than BLUEWAVE® Overcast outdoor light produces approximately 6 times more blue light. Fully shaded outdoor light produces approximately 3 times more blue light. 12
Note: 10,000 lux light is up to 50 times more intense than BLUEWAVE®. Low-intensity BLUEWAVE® causes fewer side effects. 13,14,15,16
Note: Only Apollo’s BLUEWAVE® produces the necessary bandwidth and intensity of light recommended by research. BLUEWAVE® produces no near-UV light. 17
Note: No other light therapy technology has been subjected to or passes such stringent ocular safety hazard testing. 18
Note: BLUEWAVE is safer than all other lightboxes or white light devices. 19
What are the potential side effects of Light Therapy?
In comparison to antidepressant medication light therapy has relatively few side effects. However light therapy, like any intervention (including psychotherapy) has inherent risks associated with it.1 The most common potential side effects include headaches, eye strain, nausea and agitation. These side effects may be overcome once you learn the correct amount of time for your body.Why is BLUEWAVE So Important?
- Blue light alone, and at lower intensities is more effective than white
light and white LED light, even when these light sources produce more
of the effective wavelength of blue. 20 - Blue light alone is 2 x more effective at suppressing melatonin and 2 x more
effective at regulating circadian rhythms (Melatonin and circadian
rhythms are the major factors in disorders like SAD and insomnia). 21 - Science has shown that this response is activated by the melanopsin photoreceptors in the eye. 22
- Melanopsin photoreceptors only respond to blue (~470 nm) light. 23,24
- The necessary amount of blue light is 1/50th as bright as 10,000 lux. 25
- BLUEWAVE has few or no side effects compared to 10,000 lux light.

- Spectral power distribution comparison of sunlight, 10,000 lux and BLUEWAVE® shows that BLUEWAVE® only isolates the effective blue present in 10,000 lux and sunlight. By contrast, the total amount of blue (400-500 nm) in this 10,000 lux light box is over three times that of the goLITE®

You don't need a pill for stress or anxiety!



This is how it is for me. I've had such a tough time getting this newsletter done at this time of the year. "Missspelling words, can't form my thoughts, mind going blank" this is what I've had to deal with. (Next year I'm doing this Christmas edition in July just for the feel of it!)
The second thing you can do is to see your therapist more often. Most therapists are very busy at this time of the year for just this reason. If you are feeling worse, yet overall progressing in your therapy, consider that this time of year is "filling you up".
