Neuroimaging study reveals how light-sensitive signals reach the brain and how regions associated with mood process those signals. Some regions of the cerebral cortex associated with cognitive and mood processing show sensitivity to light intensity.
More time spent outside in natural light was associated with improved mood, better sleep quality, and ease of waking.
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.
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.
According to a new study, the color of light has significant impact on our circadian clock.
