The Effects of Light on the Human Body
The blue light emitted by LED is a frequency band of 400 to 500 nanometers. Exposure to this has been shown to suppress melatonin production, a hormone critical for sleep. Blue light exposure will shift brain activity away from relaxed theta-dominant states, and towards heightened alert beta states. And so exposure in the evening will further complicate sleep patterns, which will negatively effect health in many ways.
The red light emitted is a frequency band of 620 to 700 nanometers. And it has been shown to promote bone and tissue repair and regeneration. It reduces inflammation and body fat, and it alleviates chronic and acute pain. The main reason that red light improves overall health, is because it enhances mitochondrial function throughout the entire body system. This leads to increased ATP production, reduced oxidative stress, and modulated cytokine activity. (See link for article and video)
