Blue light exposure has been shown to impact health. Natural exposure to blue light during the daylight hours boosts people's energy, alertness and mood. However, elongated exposure to the waves transmitted through screen devices during the evening can disrupt circadian rhythm and cause various health effects including a disruption in normal sleep schedules. Scientists believe this is caused by blue-light-sensitive intrinsically photosensitive retinal ganglion cells suppressing the production of melatonin and/or stimulating the suprachiasmatic nucleus of the hypothalamus.
