Decreased Melatonin Production Linked to Light Exposure
It really seems like we’re just starting to find out exactly how extensive melatonin’s influence on our health is. We starting realizing that it helps regulate our circadian rhythm. Than we found it was a powerful antioxidant in the nervous system. Now we see that it may play a role in breast cancer development. Interesting too, that female night shift workers have a much higher risk of breast cancer. Recall that sunlight exposure (and, in this case, artificial light exposure) suppresses melatonin production from the pineal gland.
This study would suggest that all night shift workers strongly consider melatonin supplementation before going to bed in the morning.
