Light at Night - There is growing interest in the role that light plays on human health, particularly nighttime exposure to short-wavelength (blue) light. Although a logical link may exist between light at night and an increased risk for diseases, it is important to point out that an empirical, scientific link between light at night of a given amount and spectral composition, and an increased risk of disease in humans has not yet been made.
Exposure to Early Evening Sunlight in Spring Delays Sleep Times - In the spring, later sunset and extended daylight exposure delay bedtimes in teenagers, according to researchers at the LRC. Biologically, this increased exposure to early evening light in the spring delays the onset of nocturnal melatonin, a hormone that indicates to the body when itís nighttime. This extended exposure adds to the difficulties teens have falling asleep at a reasonable hour. Paper published in Chronobiology International.
