Light Therapy and Sleep Disorders

Circadian Rhythm Disorders

Circadian rhythm refers to events related to the daily rotation of the earth, such as our internal body clock which regulates sleep and wakefulness.

Our bodies depend on the rising and setting of the sun to get the signal of when it's time to wake up and when it's time to fall asleep. The effect of light exposure on our circadian rhythms is critically dependent on its timing-morning light moves the sleep/wake clock earlier, while evening light shifts the clock later.

Our circadian clock is also tied to the production of melatonin, which is produced in the pineal gland. Melatonin is a naturally occurring hormone that produces "sleep" or "darkness" thereby aiding in sleep regulation. Melatonin production is also directly linked to relieving depression.

Actual Client Testimonials

"I really like the Alaska Northern Lights box. It's BRIGHT and the light is still very easy on the eyes- not all light boxes are like that. It's 10,000 lux at a couple feet, I believe, which means the box doesn't have to be right in front of my face to work for SAD. The workmanship is excellent and I'm very happy with it. I also bought the floor stand, which could use improvement in one area- it only tilts at a few set angles and can't always be set as I'd like. That said, I'd probably buy the stand again- It allows the light to be at an angle coming from above which is more natural and not only does it work great for SAD, but makes a VERY nice area task lamp with a very bright, soft, even light that covers an entire work area."
