Blue-light filtering glasses help improve sleep and work productivity, a new study reveals. The effects are most pronounced in those who consider themselves to be "night owls".
Fruit flies exposed to blue light had significantly reduced longevity than those exposed to natural light or kept in darkness. Exposure to blue light for 12 hours a day accelerated aging phenotypes, causing retinal damage, neurodegeneration, and impaired locomotion.
Study challenges the widely accepted belief that all light information is relayed through the suprachiasmatic nucleus, which synchronizes the circadian rhythm.
Rats exposed to blue light at night were more prone to indulge in sugary snacks than regular foods.
Teens who are exposed to screen time for four or more hours a day have a 30-minute delay in sleep time and report more sleep disruptions than those who spend an hour a day using tech. However, reducing screen time for a week and using glasses to block out blue light help to resolve sleep problems.
Researchers uncover how specific retinal cells respond to the artificial light generated by cell phone and tablets. The study reveals how retinal ganglion cells process ambient light and reset our circadian clocks, leading to sleep disruptions.
A number of recent research papers have warned about the effects of blue light emitted from smart phones can have on sleep patterns. A new study reveals wearing specially designed glasses with amber lenses, or using amber light functions on devices can reduce insomnia for those who use their phones at bed time.
According to researchers, daytime light exposure may help to combat the negative effect blue light exposure has on sleep.
Researchers report green light can help to promote sleep, while blue lights can delay the need to rest, at least in mice.
Researchers report reading an e-book before bed will keep you awake longer than reading a book.
