Sleep in Complete Darkness !

Maybe best to keep your nightlights off, at least according to this article from NewsTarget.

Groundbreaking research finding shows that exposure to light during sleep promotes breast cancer while darkness prevents growth of tumors. New research conducted in the United States at the National Cancer Institute and National Institute of Environmental Health Sciences reveals a startling finding: Exposure to light during the hours of sleep appears to aggressively promote breast cancer.

This effect is achieved due to light's ability to shut off production of melatonin, a hormone produced by the pineal gland. This hormone, which is naturally produced by the body during the hours of darkness, is known to be a strong immune system booster. Its presence also impedes the growth of cancer tumors by as much as 80 percent, according to research findings.

Lead researcher Dr. David Blask characterized it as, "...the first proof that light is indeed a risk factor for cancer". "Breast tumors are awake during the day, and melatonin puts them to sleep at night," adds Dr. Blask:

...and this comment from Dr. Mercola on similar subject:

"Sleep in complete darkness or as close as possible. If there is even the tiniest bit of light in the room it can disrupt your circadian rhythm".

Have a nice sleep, Rui.
