Melatonin
The pineal gland helps regulate the body’s responses to day and night cycles. The pineal gland increases production of melatonin, a hormone that synchronizes the body’s rhythms with the cycle of light and dark.
MSH, or melanocyte-stimulating hormone, is a peptide hormone produced by the pituitary gland that primarily regulates skin pigmentation by stimulating melanocytes to produce melanin. Melatonin, on the other hand, is a hormone produced by the pineal gland that regulates sleep-wake cycles and circadian rhythms. While both hormones play roles in biological processes, MSH is mainly involved in skin color and appetite regulation, whereas melatonin is crucial for sleep regulation and seasonal biological rhythms.
Melatonin is the hormone that regulates sleep-wake cycles in the body. Produced by the pineal gland, melatonin levels typically rise in the evening, signaling to the body that it is time to sleep. Disruption in melatonin production can lead to sleep disorders.
It's melatonin, secreted by the Pineal Gland.
Prolactin. There are several hormones.Growth hormone,insulin are peptide hormones
Melatonin can influence the secretion of growth hormone (GH) by promoting its release during sleep. The hormone is primarily secreted in pulses during the night, coinciding with the natural sleep-wake cycle regulated by melatonin. Additionally, melatonin may enhance the sensitivity of the pituitary gland to growth hormone-releasing hormone (GHRH), further supporting GH secretion. Overall, melatonin plays a role in synchronizing the body's growth processes with sleep patterns.

Melatonin is a hormone our body produces that makes us sleepy. Stop using any electronics at least an hour before bed because the light from the gadgets makes your body stop producing melatonin therefore you won't feel the sleepy effects from the hormone.
