Melatonin News and Research

RSS

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.

Tips to get better sleep

Your life is already tense — teens rebelling, house under renovation, work life in overload, bills piling up, elderly parents declining — yet the demands requiring your attention and time continue to grow, overflowing into sleep-time territory. Oftentimes, mass marketing's solutions to women's challenging lifestyles focus on quick fixes and more consumer goods.

Melatonin can help fight obesity and risks associated with it

University of Granada researchers have proven that melatonin -a natural hormone produced by the body- helps in controlling weight gain -even without reducing the intake of food-, improves blood lipid profile -as it reduces triglicerids-, increases HDL cholesterol and reduces LDL cholesterol.

New study sheds light on sleep problems in children with autism

The current prevalence of autism spectrum disorder is alarmingly high. Although there is no cure for autism, it is possible to manage and treat the comorbid medical conditions associated with autism. One of these conditions, sleeping disturbance, can be challenging to treat.

Vanda to initiate tasimelteon Phase IIb/III clinical trial in Major Depressive Disorder

Vanda Pharmaceuticals Inc. today announced its plans to initiate a Phase IIb/III clinical trial of tasimelteon in patients with Major Depressive Disorder (MDD). The trial is expected to begin during the second half of 2011. Tasimelteon is currently being evaluated in Phase III clinical trials for the treatment of Non-24-Hour Sleep/Wake Disorder (N24HSWD) in blind individuals without light perception.

Dementia & Alzheimer’s drug trial with sleep hormone melatonin

A new drug is in the making that could improve the quality of life for people with dementia. Glasgow-based medical research company CPS Research is conducting a clinical trial using a drug containing the sleep hormone melatonin, which it is hoped will reduce the symptoms associated with the illness.

From fatigued to fantastic! You CAN effectively treat CFS, fatigue, fibromyalgia and muscle pain

The “perfect storm” for Fibromyalgia, CFS/ME, and fatigue in general is preparing to hit. A combination of poor nutrition, decreasing sleep, increasing stress and environmental toxins has created a human energy crisis of unprecedented proportions. Over the past 10 years, the incidence of Chronic Fatigue Syndrome (CFS) and Fibromyalgia (FMS) has exploded by 400 to 1000 percent, as documented in five separate studies. The numbers for those with CFS in the U.S., previously estimated at 500,000, are now being re-tallied at closer to 1- 2.5 million. Previous estimates placed the number of Americans with FMS at 6 million. Studies worldwide suggest this has likely gone up in the last decade to ~ 12-24 million Americans! Meanwhile, ¼ of Americans suffer with chronic pain and most are fatigued.

LRC professors develop daylighting design guide for school students

The body's internal clock is responsible for regulating the timing of our sleep and other daily biological cycles, called circadian rhythms. During school months, however, teenagers miss out on essential morning light needed to stimulate the 24-hour biological clock.

Poll explores link between Americans' use of communication technologies and sleep habits

The 2011 Sleep in America- poll released today by the National Sleep Foundation finds pervasive use of communications technology in the hour before bed. It also finds that a significant number of Americans aren't getting the sleep they say they need and are searching for ways to cope.

Night shift work may reduce risk of skin cancer in women

Melatonin is known to have cancer-protective properties, and shift work can induce desynchrony of the circadian system, reducing melatonin production. Shift work has been thought to have important health impacts, with evidence linking shift work to an increased risk of several cancers including breast, endometrial, prostate, and colorectal, and non-Hodgkin lymphoma.

Study finds link between sleep duration and colorectal adenomas

An inadequate amount of sleep has been associated with higher risks of obesity, heart disease, diabetes, and death. Now colon cancer can be added to the list.

Study suggests human amniotic cells 'cross talk' with melatonin receptor MT1

Human amniotic epithelial cells, stem cells derived from human placenta left over from live births and generally discarded, proliferated and differentiated when they interacted with one kind of melatonin receptor, MT1. This potentially therapeutic response occurred when the stem cells were transplanted into laboratory test tube and animal models of stroke. The same cells did not perform similarly when interacting with melatonin receptor MT2.

Exposure to room light prior to bedtime suppresses melatonin levels, increases cancer and diabetes risk: Study

According to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism, exposure to electrical light between dusk and bedtime strongly suppresses melatonin levels and may impact physiologic processes regulated by melatonin signaling, such as sleepiness, thermoregulation, blood pressure and glucose homeostasis.
