All of us have had nights that we have struggled to sleep, or were prevented from sleeping due to our busy lives. Correspondingly, our brains on the mornings after these nights of little sleep may feel the effect in a major way. There are fluids in the brain, that are only produced during a time of slumber, which remove wastes from the cells and allow us to think clearly and focus more. If the brain did not produce cerebrospinal fluid wastes would build up and clog the spaces between blood vessels and tissues. The long lasting effects of poor sleeping habits are thoroughly explained in a TED Talk by Jeff Illiff, where he states that, “worsening sleep quality and sleep duration are associated with a greater amount of amyloid-beta building up in the brain” (Illiff).
According to Judith Owens, tweens and teenagers experience changes in circadian clocks that delay the time they are able to fall asleep. This means that with even an established bedtime, students can still wake up groggy. This is important because this fact shows that cutting down on extra activities cannot solve this sleepy dilemma. The only way we can fix this issue is by delaying start times. Secondly, according to researchers in Evanston, Illinois, teens sleep up to two hours fewer on school nights than on weekends.
Teens and kids actually function better if schools started maybe just an hour later. Students would first off get more sleep. David Dinges did a study of what kids function and reform better with so many hours of sleep. The students with 8 hours of sleep, learning curve rose and they did better at assigned tasks. Students that only got 6 hours of sleep, learning curve flattened; and the students that only slept for 4 hours were less able to perform tasks.
Dying in a dream is a stressful event, which causes your brain to release adrenaline, you can’t sleep and have an adrenaline rush at the same time so you wake up.

From this definition, sleep deprivation is then a general term used to describe “a state caused by inadequate quantity or quality of sleep, including voluntary or involuntary sleeplessness and circadian rhythm sleep disorders” (Doghramji, 2005).

This is most likely because "sleep helps the brain to commit new information to memory" (Source H) which improves learning and memory. Delaying school start times would help to improve the GPA's of students. Besides grades, getting little sleep each night also has a negative effect on health.

[has] been linked to hypertension, increased stress hormone levels, and irregular heartbeat;...[and] alters immune function, including the activity of the body's killer cells" (Source H).
