There’s no doubt we love our digital devices at all hours, including after the sun goes down. Who hasn’t snuggled up with a smart phone, tablet or watched their flat screen TV from the comfort of bed? A new study by researchers at the University of Houston College of Optometry, published in Ophthalmic & Physiological Optics, […]
Feeling sleepy? Might be the melatonin
If you walk into your local drug store and ask for a supplement to help you sleep, you might be directed to a bottle labeled “melatonin.” The hormone supplement’s use as a sleep aid is supported by anecdotal evidence and even some reputable research studies. However, our bodies also make melatonin naturally, and until a […]
Possible Role Of Melatonin In The Management Of Viral Infections
Besides playing an important role in various functions of the body, including sleep and circadian rhythm regulation, melatonin also shows immunoregulatory, free radical scavenger and antioxidant functions. Because of these latter characteristics melatonin has also been found to be effective in fighting viral infections in a variety of experimental animal and in vitro studies. These data suggest […]
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. They found that even the low light intensities of urban skyglow can suppress melatonin production. Melatonin synchronizes the day-night-rhythm in […]
Preschoolers Exposed To Nighttime Light Lack Melatonin
Exposing preschoolers to an hour of bright light before bedtime almost completely shuts down their production of the sleep-promoting hormone melatonin and keeps it suppressed for at least 50 minutes after lights out, according to new University of Colorado Boulder research. The study, published today in the journal Physiological Reports, is the first to assess the […]
Warning On Use Of Drug For Children’s Sleep
Sleep researchers at the University of Adelaide are warning doctors and parents not to provide the drug melatonin to children to help control their sleep problems. Melatonin is a hormone produced in the body with the onset of darkness. It plays an important role in fine tuning people’s circadian rhythms, such as the timing of […]
Melatonin Can Help You Get A Good Night’s Sleep In A Noisy Environment
Using melatonin could provide more and better quality sleep compared to using an eye mask and earplugs in a simulated noisy and illuminated environment, according to research published in open access journal Critical Care. This study was carried out on healthy subjects but could have future implications for intensive care unit (ICU) patients. Melatonin is the […]
