Among the other factors that have been most consistently linked to modified melatonin levels are disrupted light–dark cycles, night work and being overweight.
Beside above, what mediates the release of melatonin?
In vertebrates, melatonin secretion is regulated by activation of the beta-1 adrenergic receptor by norepinephrine. Norepinephrine elevates the intracellular cAMP concentration via beta-adrenergic receptors and activates the cAMP-dependent protein kinase A (PKA).
