Researchers report reading an e-book before bed will keep you awake longer than reading a book.
In mice, natural melatonin is linked to a pre-hibernation state, allowing for a slower metabolism and survival when food is scarce or the temperature is too cold.
Researchers identified a specific neural network that positively responds to melatonin following concussion in children. Results suggest melatonin may help compensate for normal brain function that has been interrupted due to injury caused by concussion and helps prevent sleep disturbances.
Melatonin and its metabolites promote long-term memory and protect against cognitive decline in mice.
A new study reports a small group of people with relapsing remitting multiple sclerosis experienced improvement to their symptoms during the fall and winter seasons.
Melatonin produced in the lungs acts as a barrier defense against SARS-CoV-2, the virus that causes COVID-19, by blocking the expression of genes that encode proteins in cells acting as viral entry points.
People with myopia appear to have delayed circadian rhythms and lower production of melatonin in the brain compared to those without the visual problem.
Researchers identified molecules that can modulate circadian rhythms by binding to the MT1 melatonin receptor in the hypothalamus.
According to researchers, daytime light exposure may help to combat the negative effect blue light exposure has on sleep.
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.
The brain's naturally made melatonin contributes to falling and staying asleep.
Phase shifts and melatonin suppression appear to be functionally independent, researchers report.
