Recommended: Research of sleeping habits

Seven hours ago, the sun set. It is currently 1:30 AM, and you’re still tossing in bed: awake, alert, and annoyed. Does that sound familiar? Or perhaps this strikes a louder bell: You had drifted off quickly, sinking into a slumber that should have provided your body with the precious rest it deserves, but upon awakening, your alarm has not yet gone off yet, and the clock says 2 o’clock AM. And from then on, its familiar digits slowly inched toward morning as you watched. Sleep had abandoned you. In 2011, the Centers for Disease Control and Prevention (CDC) reported that “an estimated 50–70 million adults in the United States have chronic sleep and wakefulness disorders" ("Unhealthy Sleep-Related Behaviors"). This was approximately 20% of the population. So what is causing all this trouble? The Mayo Foundation for Medical Education and Research says it could be your circadian rhythm, which “acts as an internal clock guiding such things as your sleep-wake cycle” ("Insomnia"). Your circadian rhythm is regulated by a neurohormone called melatonin, which as Johns Hopkins sleep expert Luis F. Buenaver, Ph.D., C.B.S.M. explains, “As melatonin levels rise in the evening, it puts you into a state of quiet wakefulness that promotes sleep” (qtd. in “Melatonin for Sleep”).

  • Sleep Physiology And Chronobiology Essay

    1611 Words  | 4 Pages

    We live our entire life in two states, sleep and awake1. These two states are characterized by two distinct behaviors. For instance, the brain demonstrates a well-defined activity during non-REM sleep (nREM) that is different when we are awake. In the study of sleep by Huber et. al., the authors stated that sleep is in fact a global state2. It is unclear whether this statement means that sleep is a state of global behavioural inactivity or the state of the global nervous system. The notion that sleep is a global state of the nervous system served as basis for sleep researchers to search for a sleep switch. The discovery of the sleep switch, in return, provided evidence and enhanced the notion that sleep is a global state of the nervous system. The switch hypothesis developed from the fact that sleep can be initiated without fatigue and it is reversible1. It was hypothesized that there is something in the brain that has the ability to control the whole brain and initiate sleep. Studies have found a good candidate that demonstrated this ability3. They found a group of neurons in the Ventrolateral Preoptic (VLPO) nucleus. It was a good candidate because it was active during sleep, has neuronal output that can influence the wakefulness pathway, and lesion in the area followed reduce sleep3. The idea that there is something that can control the whole brain and result sleep state supports the idea that sleep is a global state of the nervous system.

  • Sleep Diary Essay

    Although the Stanford Sleepiness Scale was the most interesting to analyze, the weeklong sleep diary allowed me to see aspects that the “Alertness Test” did not. The two biggest pieces were the effects of the program on my sleep latency and the negative impact alcohol has on sleep. First, it was one of my goals to improve my sleep latency, as during the 4 weeks of the sleep diary, my sleep latency was typically 15 minutes (higher during stressful days ex/basketball games). In order to allow for the sleep latency to decrease during emotional times, I decided to implement a 15-minute routine before I went to bed. Without a doubt, the part of the routine that was the most beneficial was turning my phone to airplane mode. Like many college students,

During their research they observed that when their patients were woken up during the REM phase, they were capable of recalling their dreams most vividly. Since then the REM has always been associated with dreaming. During REM sleep, dreams tend to be longer, more bizarre, and more complex. However, this is not the only stage of sleep in which people dream. In fact there are multiple stages of sleep in which a person can dream (Behn, Ananthasubramaniam, & Booth, 2013).
