Researchers at Ohio State University have found that the presence of light during sleep negatively affects the chemical balance and structure of the brain. Even dim light, such as a night light, interferes with the secretion of melatonin, the hormone that induces sleep.
After comparing two sets of hamsters, the researchers concluded that those sleeping in dim lighting exhibited depressive-like behaviour, as compared to those sleeping in complete darkness. This, they believe, is a result of changes that occurred in the brains after eight weeks of sleeping in dim lighting.
