Brett Smith for redOrbit.com - Your Universe Online People working the graveyard shift may want to literally see red because according to a new study -- the color of light animals are exposed to at night can affect mood regulation. Study researchers from The Ohio State University found hamsters that were exposed to blue lights at night experienced the worst mood disruptions, followed closely by white lights, when compared to hamsters that spent their nights in a dim red light. "Our...

Chronic exposure to dim light at night can lead to depressive symptoms in rodents -- but these negative effects can be reversed simply by returning to a standard light-dark cycle, a new study suggests. While hamsters exposed to light at night for four weeks showed evidence of depressive symptoms, those symptoms essentially disappeared after about two weeks if they returned to normal lighting conditions. Even changes in the brain that occurred after hamsters lived with chronic light at...

New research provides the best evidence to date that the late-day anxiety and agitation sometimes seen in older institutionalized adults, especially those with dementia, has a biological basis in the brain. The findings could help explain "sundowning," a syndrome in which older adults show high levels of anxiety, agitation, general activity and delirium in late afternoon and evening, before they would normally go to bed. "It's a big problem for caregivers. Patients can get aggressive and very...

Exposure to even dim light at night is enough to cause physical changes in the brains of hamsters that may be associated with depression, a new study shows. Researchers found that female Siberian hamsters exposed to dim light every night for eight weeks showed significant changes in a part of the brain called the hippocampus. This is the first time researchers have found that light at night, by itself, may be linked to changes in the hippocampus. These alterations may be a key reason why the...

(Ivanhoe Newswire) -- If you're wishing upon a star in hopes to stop packing on the pounds, you might already be jinxing yourself.  A recent study finds that continual exposure to light at night may lead to weight gain, even without changing physical activity or eating more food.  Researchers say that instead of wishing upon the stars . . . maybe you should sleep under them. Researchers found that mice that were exposed to a moderately dim light at night over eight weeks had a body...

Persistent exposure to light at night may lead to weight gain, even without changing physical activity or eating more food, according to new research in mice. Researchers found that mice exposed to a relatively dim light at night over eight weeks had a body mass gain that was about 50 percent more than other mice that lived in a standard light-dark cycle. "Although there were no differences in activity levels or daily consumption of food, the mice that lived with light at night were getting...

Too much light at night can lead to symptoms of depression, according to a new study in mice. Researchers found that mice housed in a lighted room 24 hours a day exhibited more depressive symptoms than did similar mice that had a normal light-dark cycle. However, mice that lived in constant light, but could escape into a dark, opaque tube when they wanted showed less evidence of depressive symptoms than did mice that had 24-hour light, but only a clear tube in their housing. "The ability to...
