Breast milk may help train the circadian clock in young babies. The hormonal composition of breast milk changes throughout the day, with cortisol levels being higher in the morning and melatonin levels being higher at night.
A retrospective analysis finds a correlation between sleep disorders and a lack of essential vitamins and minerals.
Researchers have created new 3D maps of two melatonin receptors. The models can be used to help develop new treatments that not only improve sleep, but may also treat a variety of other conditions from diabetes to cancer.
A new study reports women who are in their third trimester of pregnancy during months with less day light are at an increased risk of developing postnatal depression.
Researchers report a variation of the MTNR1A gene is linked to an increased risk of developing Alzheimer's disease in older people. The same gene has previously been implicated in reduced tolerance to shift work in the aging population.
According to a new study, melatonin works by suppressing neurons that keep you awake and alert. The findings could pave the way for new treatments for insomnia.
Phase shifts and melatonin suppression appear to be functionally independent, researchers report.
According to researchers, those who eat in close proximity to their natural melatonin onset are more likely to have a higher percentage of body fat and BMI than those who eat earlier.
A new study reveals those with the 'night owl' variant of the CRY1 gene have longer circadian cycles than other people, making them stay awake for longer at night.
According to a new study, synthetic chemicals found in some insecticides can bind to melatonin receptors, creating a higher risk for people to develop diabetes and other metabolic disorders.
According to researchers, daytime light exposure may help to combat the negative effect blue light exposure has on sleep.
Researchers report our gut bacteria is sensitive to melatonin and expresses its own circadian rhythm.
