Blue Light Exposure

Meaning

Blue Light Exposure refers to the body’s absorption of high-energy visible (HEV) light in the blue wavelength spectrum, predominantly emitted by digital screens, LED lighting, and natural sunlight. While daytime exposure is essential for regulating alertness and mood, chronic or ill-timed exposure, particularly in the evening, is a critical factor in disrupting hormonal health. This light spectrum carries a significant biological signal that the body interprets as daylight, directly interfering with the neuroendocrine system. Minimizing evening blue light is a key component of modern health and longevity protocols aimed at preserving endogenous hormonal rhythms.
