Worms reveal why melatonin promotes sleep
Melatonin is used as a dietary supplement to promote sleep and get over jet lag, but nobody really understands how it works in the brain. Now, researchers at UConn Health show that melatonin helps worms sleep, too, and they suspect they've identified what it does in us. (2020-11-13)

Another grape excuse to hit the bottle
Scientists in Italy say they have discovered that the grapes used to make red wine contain high levels of the sleep hormone melatonin.This could explain why so many of us hit the bottle in the evening to wind down after a day's hard slog. 'The melatonin content in wine could help regulate the circadian rhythm [sleep-wake patterns], just like the melatonin produced by the pineal gland in mammals,' says researcher Iriti Marcello at the University of Milan. (2006-06-16)

Study links diabetes risk to melatonin levels

Use public funds to test jet lag drug, say researchers
The hormone melatonin has long been used to prevent and treat jet lag, but in many countries it cannot be sold because it is not licensed. Researchers in this week's BMJ argue that if use of the drug is in the public interest, then public funds should be used to get it adequately tested to be licensed. (2003-02-06)

Could melatonin be the key to healthy aging?
A new British Journal of Pharmacology review highlights the role of melatonin -- a hormone that is produced at night -- in regulating sleep and the body's biological, or circadian, clock. Research suggests that melatonin treatments may even help to improve the restorative value of sleep and to promote healthy physical and mental aging. (2018-01-10)

Melatonin reduces blood pressure and tunes up disrupted circadian rhythms in the elderly
Increased blood pressure and reduced robustness of circadian rhythms are frequently reported in elderly subjects. The present study was aimed to investigate whether such changes can be reversed by daily melatonin ingestion. (2016-05-17)

Total darkness at night is key to success of breast cancer therapy -- Tulane study

Asthma patients cautioned about melatonin
People with asthma should consider limiting the use of melatonin as a sleep aid, according to researchers from the National Jewish Medical and Research Center. Pulmonologist Rand Sutherland, M.D., M.P.H., and his colleagues report in the September issue of the Journal of Allergy and Clinical Immunology that higher levels of endogenous melatonin were associated with an overnight loss of lung function in asthma patients. Widely available supplements can raise melatonin blood levels 10 to 100 times higher than normal peak levels. (2003-09-08)

Melatonin may not help prevent delirium after heart surgery
Delirium is observed in approximately 15% of hospitalised older adults, and it is more common in the critically ill and in those undergoing major surgery, such as heart surgery. Studies have found that blood levels of melatonin, a serotonin-derived hormone, decrease following surgery and are lower in surgical patients who develop delirium. A new study published in the Journal of the American Geriatric Society found that melatonin treatment did not influence the risk of developing delirium following heart surgery, however. (2019-10-09)

Light pollution can suppress melatonin production in humans and animals
Melatonin sets the internal clock. Researchers from Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) in an international team have analyzed data on the impact of light pollution on melatonin formation in humans and vertebrates.

Melatonin improves mood in winter depression
OHSU researchers tested the hypothesis that circadian physiological rhythms become misaligned with the sleep/wake cycle during the short days of winter, causing some people to become depressed. After four years of study, they found that circadian misalignment is a major part of SAD and that low-dose melatonin improves mood among winter depressives. (2006-05-01)

Melatonin: finally, a supplement that actually boosts memory
Researchers at Tokyo Medical and Dental University (TMDU) showed that melatonin's metabolite AMK can enhance the formation of long-term memories in mice. Memory of objects were tested after treatment with melatonin or two of its metabolites. Older mice that normally performed poorly on the memory task showed improvements as dosage increased. The metabolite AMK was found to be the most important as melatonin failed to improve memory if it was blocked from metabolizing into AMK. (2020-12-10)
