Light Wavelength Effects

Meaning

Light Wavelength Effects describe the specific biological and physiological responses triggered in the human body by exposure to different regions of the electromagnetic spectrum, particularly visible and non-visible light. This concept is critical in hormonal health because specific wavelengths, such as blue light, directly modulate the circadian rhythm and the secretion of key hormones like melatonin and cortisol. Conversely, certain red and near-infrared wavelengths can penetrate tissue to influence mitochondrial function and cellular repair. Understanding these effects allows for the precise use of light exposure as a non-pharmacological therapeutic tool.
