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 bought my light before last winter and used it for the first time during the 2011-2012 winter season. I've had seasonal mood swings for as long as I can remember and have always struggled through the winters with anxiety and feeling down. This light is wonderful. I use it in the morning while reading the paper and drinking tea. It helps me wake up and brighten my mood. Thank you for producing an affordable medical grade product the public can buy."
