A bad night's sleep can ruin your entire day. Consistently getting poor sleep, though, is enough to make a person crack — or at least turn to Dr. Google in desperation. Melatonin is often ...
Melatonin, an indoleamine, is a natural compound produced by various organisms, including bacteria and eukaryotes. [1] Its discovery in 1958 by Aaron B. Lerner and colleagues stemmed from the isolation of a substance from the pineal gland of cows that could induce skin lightening in common frogs.
Large doses of melatonin can even be counterproductive: Lewy et al. [48] provide support to "the idea that too much melatonin may spill over onto the wrong zone of the melatonin phase-response curve." The long-term effects of melatonin administration have not been examined. In some countries, the hormone is available only by prescription or not ...
Excessive daytime sleepiness (EDS) is characterized by persistent sleepiness and often a general lack of energy, even during the day after apparently adequate or even prolonged nighttime sleep.
But sundowning has some unique signs that make it stand out from just being tired. “Fatigue can occur at all times of the day. Sundowning is truly confusion,” Dr. Kobylarz says.

Melatonin may be useful in the treatment of delayed sleep phase syndrome. [9] Melatonin is known to reduce jet lag, especially in eastward travel. However, if it is not taken at the correct time, it can instead delay adaptation. [30] Melatonin appears to have limited use against the sleep problems of people who work shift work. [31]
