Do you sleep with lights on or off?

sleep is very much essential for a good health....as Sleep is the state of natural rest observed in most mammals, birds, fish, and even invertebrates such as the fruitfly Drosophila. It is characterized by a reduction in voluntary body movement, decreased reaction to external stimuli, an increased rate of anabolism (the synthesis of cell structures), and a decreased rate of catabolism (the breakdown of cell structures). In humans, mammals and many other animals which have been studied, such as fish, birds, mice and fruitflies, sleep is necessary for life. The capability for arousal from sleep is a protective mechanism and also necessary for health and survival. Sleep is not synonymous with unconsciousness. so sleeping with the lights off is good for the health
