Melatonin News and Research RSS Feed - Melatonin News and Research

Melatonin, also known chemically as N-acetyl-5-methoxytryptamine, is a naturally occurring compound found in animals, plants, and microbes. In animals, circulating levels of the hormone melatonin vary in a daily cycle, thereby allowing the entrainment of the circadian rhythms of several biological functions.

Electro-acupuncture may be effective in treating sleep disturbances in women with breast cancer

It's somewhat of a little-known adverse effect of having breast cancer, but studies suggest that approximately 30% to 40% of women with breast cancer report persistent hot flashes. Nocturnal hot flashes are among the most problematic because they can contribute to poor sleep. [More]

New study examines genetic factors underlying poor tolerance to shift work

New study examines genetic factors underlying poor tolerance to shift work

Some people adapt easily to shift work, but not everyone can handle constant disruptions to their daily rhythm. Finnish researchers have now found that a melatonin receptor gene influences tolerance to shift work. [More]

Vanderbilt sleep specialists offer tips to manage daylight saving time transition

When daylight saving time ends at 2 a.m. on Sunday, Nov. 6, we set clocks back one hour, and essentially gain an extra hour of sleep—but that extra hour of sleep comes at the price of early evening darkness. [More]
Regulating mealtimes during days off can help alleviate jet-lag in long-haul cabin crew

Regulating mealtimes during days off can help alleviate jet-lag in long-haul cabin crew

A study published today in the journal Psychology and Health has found that jet-lag in long-haul cabin crew is alleviated when meal times are regulated on their days off. [More]
Prescription sleep aids may stimulate suicidal thoughts or actions

Prescription sleep aids may stimulate suicidal thoughts or actions

Prescription sleep aids appear to carry a rare risk of suicide, most typically when they cause the unexpected response of stimulating rather than quietening patients, researchers say. [More]

Melatonin, a hormone produced in the human brain, appears to suppress the growth of breast cancer tumors. [More]
Research highlights interaction between biological clock and sleep loss at regional brain level

Research highlights interaction between biological clock and sleep loss at regional brain level

Ever wondered what happens inside your brain when you stay awake for a day, a night and another day, before you finally go to sleep? In a new study published today in the journal Science, a team of researchers from the University of Liege and the University of Surrey have scanned the brains of 33 participants across such a 2-day sleep deprivation period and following recovery sleep.

NLCs packed with melatonin could increase effectiveness of tamoxifen drug

NLCs packed with melatonin could increase effectiveness of tamoxifen drug

Tiny bubbles filled with the sleep hormone melatonin can make breast cancer treatment more effective, which means people need a lower dose, giving them less severe side effects. [More]
Late sleep timing linked to lower BMI, poorer diet quality and lower physical activity

Late sleep timing linked to lower BMI, poorer diet quality and lower physical activity

A new study suggests that among healthy adults with a habitual sleep duration of at least 6.5 hours, late sleep timing was associated with higher fast food consumption and lower vegetable intake, particularly among men, as well as lower physical activity. [More]
Melatonin can be of great value for elderly people suffering from hypertension

Melatonin can be of great value for elderly people suffering from hypertension

The older we get, the more likely our circadian rhythms are disrupted. For example, blood pressure (BP), not only tends to increase but as well become more irregular. Luckily, as we show in our research, melatonin helps to ameliorate both trends. [More]
Sleep hormone melatonin may be responsible for type 2 diabetes risk among overnight workers

Sleep hormone melatonin may be responsible for type 2 diabetes risk among overnight workers

A new experimental and clinical study from Lund University in Sweden shows that the sleep hormone melatonin impairs insulin secretion in people with a common gene variant. [More]
Exposure to blue light may lead to eyestrain but does not damage retina

Exposure to blue light may lead to eyestrain but does not damage retina

Nearly 90 percent of adults use digital devices for two or more hours per day, according to The Vision Council's 2016 Digital Eye Strain Report, exposing consumers to blue light that some suggest is dangerous. [More]
Research: X and Y DNA swapping may occur more often than previously thought

Research: X and Y DNA swapping may occur more often than previously thought

It turns out that the rigid "line in the sand" over which the human sex chromosomes---the Y and X--- go to avoid crossing over is a bit blurrier than previously thought. Contrary to the current scientific consensus, Arizona State University assistant professor Melissa Wilson Sayres has led a research team that has shown that X and Y DNA swapping may occur much more often.

The Monday after daylight saving time takes effect doesn't have to be a heart-stressed, mad-dash, car-crash kind of a day. [More]
Children taught at home get more sleep than others

Children taught at home get more sleep than others

A new study published in Behavioral Sleep Medicine shows that children who are taught at home get more sleep than those who go to private and public schools. The findings provide additional evidence of teens' altered biological clocks and support an argument for starting traditional high school later in the morning. [More]

IU researchers discover hormonal mechanism that links short winter days with increased aggression in females

Indiana University researchers have discovered a hormonal mechanism in hamsters that connects short winter days with increased aggression in females, and that it differs from the mechanism that controls this same response in males. [More]
