Full Spectrum Light Input

Meaning

Full Spectrum Light Input is the exposure of the human body, specifically the eyes and skin, to light that contains all wavelengths of the visible and non-visible electromagnetic spectrum present in natural sunlight. This comprehensive input is critical for accurately synchronizing the body’s master circadian rhythm, optimizing vitamin D synthesis, and stimulating the proper release of key neurotransmitters and hormones. Adequate exposure is foundational for regulating healthy sleep-wake cycles, mood stability, and robust endocrine function.
