Neuroscience research show that sleeping with the light on can make hamsters depressed.

November 18, 2010

This might suggest that falling asleep in front of the TV is not such a good idea.

"Even dim light at night is sufficient to provoke depressive-like behaviors in hamsters, which may be explained by the changes we saw in their brains after eight weeks of exposure," said Tracy Bedrosian, co-author of the study and doctoral student in neuroscience at Ohio State University.

Bedrosian and her colleagues presented the results Nov. 17 in San Diego at the annual meeting of the Society for Neuroscience.

The results are significant because the night-time light used in the study was not bright: 5 lux, or the equivalent of having a television on in a darkened room, said Randy Nelson, co-author of the study and professor of neuroscience and psychology at Ohio State.

    This study appears to be a great example of “bad science”.

    5 lux of light is roughly equivalent to having a television on in the room, which does NOT equate to a low-light environment. Plain and simple the hamster were suffering from sleep deprivation.
    Also, I didn’t see any data in the indicating wheter or not the researchers had analyzed the light-blocking capacity of a hamster eyelid?
