In Reply to: Melatonin as a cure ? posted by Doug on October 31, 2001 at 16:53:27:
My clusters come every 2 1/2 years. What kind of light change happpens every 2 1/2 years?
Melatonin is a product of serotonin. Serotonin is what controls the blood vessels in dialation and contraction by sending signals to the smooth muscle surrounding the vessels. We know our serotonin is messed up so it figures our melotonin would be also (this is shown in studies).
It all comes back to the good old hypothalamus. It is the body clock. It controls some of the other glands. Telling them when to produce serotonin and when not to. I think our body clocks get messed up because of the deformity in the hypothalmus, not becasue of changes in light.
Just my humble opinion.
