The Pineal Gland Hormone,melatonin,is Affected by the Amount of Light

Question

The pineal gland hormone,melatonin,is affected by the amount of light to which a person is exposed.

Accepted Answer

Melatonin production is regulated by light and dark cycles, with levels rising in the evening in response to decreased exposure to light and declining in the morning in response to increased exposure to light. The production of melatonin is inhibited by exposure to bright light, particularly blue light, which is why it is often recommended to avoid electronic screens before bed to promote healthy sleep patterns.
