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. To ensure better sleep, blue light should be decreased at night.
