In a novel study researchers have warned that sleeping with light on could make the feeling of the next day low. They found that a nigh light though dim it may be can affect the makeup of mind and raise the chances of depression.
The uncanny glow released by television or ostensibly comforting incidence of a night light could be enough to impact on mental health. This is the most recent a long line of caution about the possible hazards of distracting the normal sleep-wake cycle of the body.
There are also worries that shift class of workers are at larger risk of breast cancer and the previous study has connected night light with gain in weight. The complete darkness which hard to obtain in the modern world could have serious insinuations for health, according to experts.
The effects of exposing to rodents to dim light is studied by researchers from Ohio State University, in eight hours or when they would usually be asleep. At the equal of having a television on in a darkened room, the lamp used was not bright, but it was enough to affect the behavior of an animal.
One depression test calculated the quantity of sugared water the creatures drank, with a lack of curiosity in the sweet treat indicating a change in mood. Generally, those exposed to the dim light at night showed more symptoms of depression in comparison to the hamsters in the normal light-dark cycle.
More tests demonstrated dissimilarities in the makeup of a brain region called the hippocampus. The hippocampus plays significant role in depressive disorders, so finding changes there is significant. Even dim light at night is enough to incite depressive behavior, explained lead researcher Tracy Bedrosian.
