Light in Sleeping Spaces (04-15-10)

Light shielding in spaces for sleeping is crucial.  Ben-Shlomo and Kyriacou have found that when rats are exposed to light for part of their sleep period (one hour out of 12), cell division is adversely affected in ways that are consistent with cancer and the fight against cancer.  The study findings encourage the use of curtains or other elements to keep spaces dark during sleep.
