I. Attention Gainer: “Even though we burn more calories when we stay awake, losing sleep is not a good way to lose weight. The light sleepers ended up eating far more than those who get nine hours of sleep.” According to author Tara Parker-Pope of The New York Times published on March 18, 2013. II. Thematic Statement: Most people don’t think about the long term effects of not getting enough sleep you need to function properly. But if we all were to go to bed at a reasonable time, then not only will it improve your physical health it will also improve your mental health.
III. Preview: I am going to begin by talking about how much sleep do we need according to our age? Then what goes on with our brains during sleep and lastly I will explain the implications of lack of sleep. Body:
I. Main Point #1 (How much sleep do we need according to our age) A. According to The National Sleep Foundation last updated March 22nd, 2014 “ Studies confirm that on average adults need at least 7 to 9 hours of sleep to complete all stages of sleep.
” Also after further research newborns 1 month to 2 months old need 14 to 18 hours, Infants 3 to 11 months old need 13 to 16 hours, toddlers and children need about 11 hours, and teens need 9 to 10 hours. These variations of sleep time is because of growth and repairs the brain and the body need. Neither can be obtained if you’re always up. B. The Centers for Disease Control and Prevention website last updated January 13, 2014 states that “50-70 million U.
S Citizens have been recorded to have sleep deprivation (or lack of sleep) caused by various reasons.” Various reasons meaning that the lack of sleep could be anything from a medical problem to self-infliction of sleep deprivation. Internal Summary #1: Now that we are aware of the amount of sleep we need, let’s now discuss about our brain activity during sleep.
II. Main Point #2 (What goes on with our brains during sleep) A. According to The National Institute of Neurological disorders and stroke last updated April 28th, 2014 “During sleep, we usually pass through five phases of sleep: stages 1, 2, 3, 4, and REM (rapid eye movement) sleep.” The article also states that 50 percent of our sleep is during stage 2, 20 percent in REM sleep, and the other 30 percent in the remaining stages. B. Stage 1 of sleep is also known as light sleep where we drift in and out of sleep. This stage is where we can be woken up the easiest. Stage 2 is where our brain activity and eye movement start to slow down and stop. Stage 3 brain waves start to begin with slow and fast movements. Stage 4 also known as deep sleep is the toughest stage to wake someone up. It is the stage where there is no eye movement or muscle activity and if you were to awaken during this stage. The results would be the feeling of grogginess or disorientation. The last stage REM sleep aka Rapid Eye Movement is the dream stage of sleep. Where we fantasize about our life and day occurrences. Internal summary #2: We have discussed what goes on with our brains during sleep, let’s finish with the implications lack of sleep has on our society.
III. Main Point #3 (Implications)
A. Sleep is a very important factor in our everyday lives in fact according to The National Association of Science last updated April 14, 2014 “Sleep deprivation can cause severe cases of anxiety and can also lead to insomnia.” B. Without sleep our brains cannot not work to the best of its abilities. Scientists can’t discover new things, students will continue to fall asleep in class, and people that work 9 to 5 jobs could and will go mentally insane. Conclusions:
I. Summary Statements: We are now familiar with the amount of sleep we need depending on ages, what our brain activity is like during sleep, and how sleep impacts us all as a society. II. Concluding Remarks: Since I researched this topic very thoroughly I can now help people who refuse to sleep for decent hours realize what they are doing to themselves.
