Your brain tracks the time of day with special receptors in the eye that sense lighting conditions. These receptors are extremely sensitive to blue light. This is a problem because LED lighting and electronic screens blast blue-rich light directly into your eyes! These daytime signals after dark can scramble your natural circadian rhythm.
