Sleep Deprived

     It is no surprise that a night without enough sleep can lead to a groggy morning, but that is not the only thing that can happen when the body needs more sleep. There are more frightening effects to sleep deprivation, if a person is deprived of sleep it can lead to emotional and physical problems. Research over the years has shown that people can be physically and psychologically damaged from not getting enough sleep. Learning what happens in people who are sleep deprived can help researchers better understand the function of sleep and its importance for both physical and emotional health. In the article, Sleep Deprivation Produces Feelings of Vicarious Agency by Nicholas Hon and Jia-Hou Poh, studies the effects of being in a non-optimal state, when sleep deprived on judgement agency. They found that 24 hours of total sleep deprivation elevated agency ratings on trials designed to produce sense of non-agency. That data provides the first evidence that physiological state variables can affect agency processing in the normal population. In the study, the 36 participates had regular sleep habits, were not on any long-term medications, had no history or symptoms of sleep disorders and drank less than 3 caffeinated drinks per day.  The sleep patterns were monitored by a wrist-worn actigraphy throughout the study. Their main finding was that being in a sleep-deprived state had a reliable effect on an individual’s ability to accurately sense a lack of agency in each outcome. They observed that sleep deprivation produced vicarious agency in non-agency. However, the ratings on agency trials were unaffected by TSD. They propose that the TSD affects the comparison process, that quality of the mismatches between the predicted and actual outcomes. Their data suggests that mismatch processing within the context of agency judgment was also affected by TSD. The neuroimaging studies revealed that sensing non-agency is associated with a network of frontal and parietal areas which include the dorsolateral prefrontal cortex, angular gyrus and temporoparietal junction. In their conclusion, although agency distortions are observed, they demonstrate a distortion that is a consequence of non-optimal state. That this represents the first evidence that physiological state variables can influence agency processing.

sleep deprivation is a very common problem among teenagers and young adults. Sleep deprivation has a major affect on your immune system and many other parts of your life. This journal is very descriptive and has sophisticated language. I would only recommend involving personal examples of how sleep deprivation has affected a persons life and the chemicals in the brain that are affected.

You've brought attention to a topic that should be talked more about. Driving with an undiagnosed sleep problem, like sleep apnea also adversely affects the general public. See what the CDC says about sleep and driving, as well: https://www.cdc.gov/features/dsdrowsydriving/.

Sleep deprived is a very important topic. I think also peoples daily schedules play a big part of this. Some jobs people work overnight and try to sleep during the day, which is hard if someone needs to make a doctor appointment or do errands. For example policeman work all kinds of strange hours. so how does one fix these difficult schedules when jobs are needed all through the night?

I understand first-hand the dilemma of sleep deprivation because I have apnea. In your article it referenced candidates without sleep disorders, there are also environmental issues impacting quality of sleep. For example Alaskan summers poses serious consequences for its occupants. They have to manufacture a nocturnal sleeping place to compensate for the lack of darkness.
