Referring to following link, I would like to know on how reducing melatonin effects on maintaining circadian rhythms.

Does anyone have any suggestions?
Thanks in advance


"Proper levels of melatonin secretion are important for human health, and the hormone is involved in a wide range of processes not discussed here. Perhaps because the pineal gland is highly specialized, focusing only on melatonin secretion, its importance is sometimes overlooked. The significance of melatonin in maintaining circadian rhythms, however, and the pineal gland's role in producing it, suggest that the pineal gland is an essential structure for the health of the central nervous system."

IPRG cells is photo sensitive cell affecting circadian clock
IPRG Cell would be depolarized with light, which inhibition of endocrine functions of pineal gland,
therefore, there is no secretion melationin production.

I would like to know on whether blue light would be better for IPRG cell depolarize or not as comparing with red light.

Does anyone have any suggestions?
Thanks in advance

Melatonin is a neurohormone produced in the pineal gland that regulates circadian rhythmicity, with maximal secretion at night.

How does Melatonin effect heart rate and perpiration breathing?

Would increasing Melatonin increase heart rate and perpiration breathing?

How does Melatonin effect heart rate and perpiration breathing?

Melatonin-induced bradycardia may be related to a muscarinic receptor activation and melatonin-induced tachycardia may be related to a Beta-adrenoceptor stimulation.

I wish I could provide more input, expect the entire paper is written in Korean. Though since heart rate and breathing are connected via the parasympathetic nervous system, a high heart rate would be associated with more breathing, and vice versa.
