A hormone (a chemical produced by the body and carried by the bloodstream to another part of the body to stimulate or retard its function) produced in the hypothalamus of the brain that causes a drop in body temperature and sleepiness
hormone secreted by the brain's pineal gland
— hormone secreted by the pineal gland that is involved in the sleep/wakefulness cycle
in nature, a hormone that is secreted by the pineal gland in the brain in response to darkness, and has been linked to regulation of circadian rhythms; a derivative of melatonin marketed as a health food supplement is commercially available
This hormone regulates and synchronizes hormone secretions in the body and has been shown to produce a calming effect Melatonin is also thought to possess antioxidant-like qualities
a hormone secreted by the pineal gland used as a marker of circadian rhythmicity in humans
Melatonin levels follow a precise circadian pattern with high levels at night and low to undetectable levels during the day This fluctuation controls the body's sleep-wake cycle Decreased levels of melatonin during the night can cause difficulty falling to sleep and reduce the restfulness of sleep There is also some evidence that melatonin boosts immune system function, lowers cholesterol in people with high levels, and may be useful in treating or preventing cancer

a hormone produced by the pineal gland that regulates circadian rhythms; helps induce sleep and acts as an antioxidant
a hormone that is sometimes used as a drug to help you sleep (melas + serotonin). Hormone secreted by the pineal gland of most vertebrates. It appears to be important in regulating sleeping cycles; more is produced at night, and test subjects injected with it become sleepy. Melatonin may be involved in seasonal affective disorder. In mammals other than humans, melatonin may act as a cue to breeding and mating in season
hormone secreted by the pineal gland
A hormone that can influence the hypothalamus and pituitary gland and may affect appetite and sleep It is derived from the amino acid, tryptophan
Melatonin is a substance secreted by the pineal gland that passes by way of the blood or through the fluid of the third ventricle to the anterior pituitary gland to control gonadotropic hormone secretion; melatonin can be manufactured artificially and is showing several possible beneficial medical uses
A hormone produced by the pineal gland that regulates the level of activity in the brain
The only hormone secreted into the bloodstream by the pineal gland The hormone appears to inhibit numerous endocrine functions, including the gonadotropic hormones Research exists on the efficacy of melatonin in treating jet lag and certain sleep disorders Dosages greater than l milligram have been associated with drowsiness, headaches, disturbances in sleep/wake cycles and is contraindicated in those who are on antidepressive medication It also negatively influences insulin utilization
