The researcher's statement to answer his research question was made by explaining the three reasons why we sleep. These reasons relate to restoration, energy conservation and brain function. When we fall asleep, all the information and different things we learned throughout the day are restored to our brain. In the brain, a series of genes activate only during sleep, associated with restoration. We sleep to save calories and energy. When we sleep, our brains process new solutions to complex problems. Sleeping improves creativity because important neurological connections are linked and strengthened. Fussel also explains how the body clock does not adapt to the demands of night work. The body clock tells people who are trying to sleep during the day that it is not time to sleep and night shift workers are not getting the amount of sleep they need. Another form of sleep that we are all familiar with is micro-sleep. Microsleep occurs when the human body involuntarily falls asleep while trying to stay awake. The human body has no control over this form of sleep. Lack of sleep leads to poor memory, poor judgment and increased impulsivity. When we're sleep deprived, our bodies crave stimulants like caffeine and drugs. Result of alcohol making you fall asleep. Fussel explains that alcohol doesn't actually help you fall asleep, it calms you down. This damages neurological processing that occurs during memory consolidation and brain processing during sleep. Loss of sleep can
