Quizplus · Accepted Answer

Sleep is a physiologically prompted state of reduced consciousness. While sleep involves a reduction in activity in many parts of the brain, it is not a state of complete shutdown as the brain remains active during sleep. While darkness may help to promote sleep, it is not the only factor and other factors such as our internal circadian rhythm also play a role. Similarly, while reduced stimulation from the environment may help to promote sleep, it is not the only factor and some people are able to sleep through noise or other distractions.
