The Science of Amber Sleep Lamps
The blue light contained in sunlight and SAD lamps is highly beneficial in the morning, preventing Seasonal Affective Disorder, non-seasonal depression, and circadian rhythm disorders. Blue wavelengths of light tell our bodies to that it’s daytime. However, at night, these same blue wavelengths can block up to 99% of our bodies’ melatonin production, causing insomnia, shift work disorder, and even significant increases in rates of cancer and diabetes. Common lighting devices like computer screens, fluorescent lights, and cellphone screens emit high levels of blue light. Numerous studies demonstrate that limiting your nighttime exposure to amber wavelengths of light, either through the use of amber sleep lamps or blue-blocking amber glasses will allow healthy melatonin production (an average increased melatonin production of 90 minutes), leading to healthier sleep patterns and reduced insomnia.

The LowBlueLights booklight features 18 amber LEDs, to ensure healthy melatonin production in the evening. Includes a 3-foot A/C adapter for direct power. Internet browsing at night has been demonstrated to exacerbate insomnia in two ways: overstimulation and blue light emission. In contrast, reading a traditional or e-ink book in the evening has been shown to significantly decrease sleep latency and increase overall sleep satisfaction. Find LowblueLight’s book light here.
Cons: Only one brightness setting, and a very short battery life (around 1 week between changing batteries).
