The problem with artificial light

All artificial light, including LEDs, fluorescent bulbs and incandescent bulbs, can interrupt normal sleep patterns. The body's biological clock works in rhythms that are set by the amount of light and dark the body is exposed to. This is called the circadian rhythm. Circadian rhythms control the timing of many physiological processes. They determine sleeping and feeding patterns, as well as brain activity, hormone production and cell regeneration. 

Blue Light

Blue light encourages the body to produce Cortisol, which is a hormone designed to wake up the body. So blue light exposure before sleep is counter productive!

Melatonin Inhibitor

Research has found that exposure to blue light suppresses the production of melatonin more than any other type of light. It is believed that the shorter wavelengths in blue light is what causes the body to produce less melatonin.

Real Science

A study by the University of Toronto found that those who wore glasses that blocked blue light wavelengths produced more melatonin than those who didn't during night shifts.

The Problem

Other studies have found that blue wavelengths suppress delta brainwaves, which induce sleep, and boost alpha wavelengths, which create alertness. To get better sleep, it would be best to stop using artificial light altogether, but that isn't possible in modern times.
