Melatonin and sunlight are intimately linked and the relationship is unique in the fact that there are two melatonin forms, circulatory and subcellular. Both appear to be controlled by either the absence of sunlight or the presence of sunlight.

  • While circulatory melatonin may be the ‘hormone of darkness’ associated primarily with sleep, subcellular melatonin may be the ‘hormone of daylight’ that acts as an antioxidant reservoir in the mitochandria,
  • This subcellular melatonin does not necessarily fluctuate with our circadian clock or release into the circulation system, but instead has been proposed to be consumed locally in response to the free radical density within each cell. 
  • The main point is that subcellular melatonin is being produced in response to near-infrared light photons which make up the majority of natural sunlight (excerpted: Melatonin and the Optics of the Human Body).
