There is no formal definition of liberal arts college, but one American authority defines them as schools that emphasize undergraduate education and award at least half of their degrees in the liberal arts fields of study.. Other researchers have adopted similar definitions.
âMelatonin is an important regulator of brown adipose tissue in mammals, which burns calories by ramping up the bodyâs metabolism,â Fridlund said. In addition, human bodies naturally adjust melatonin production levels in response to changes in light.
Melatonin is produced by the pineal gland and sends a signal to regulate the sleep-wake cycle in the sleep center of the brain. Interestingly, melatonin is also produced in the retina, the skin, and the GI tract, but this is not the melatonin what affects your biological sleep clock. This is the really important thing you should understand about melatonin: Melatonin is a sleep and body clock regulator â NOT a sleep initiator. Melatonin works with your biological clock by telling your brain when it is time to sleep.
