¶ … Sleep Behavior and Habits
Scientists have known for decades that the human sleep and wakefulness are controlled by complex factors that influence the circadian rhythm that regulate sleep in all mammalians and in most other forms of so-called higher biological life. More recently, physiologists have identified very important direct connections between sleep cycles, and sleep deprivation in particular, and human health. Specifically, sleep deprivation and the disruption of regular sleep-wake cycles have been implicated as factors that contribute to loss of mental focus, intellectual productivity, human error, emotional stability, resistance to bacterial infection, depression, and even healthful weight maintenance. In addition to the importance of sufficient sleep and the regularity of sleep cycles, there is even empirical evidence indicating that the quality of sleep is significantly affected by very small amounts of ambient light during sleep.
The Physiological and Psychological Importance of Sleep
Human studies on sleep and on sleep deprivation have demonstrated that human beings cannot function without sufficient sleep (Siegel, 2005). After only one night of inadequate sleep, mental acuity, memory, operational efficiency, and mood deteriorate substantially. For this reason, regulatory agencies impose strict requirements and limitations on the amount of time in between the shifts scheduled for truck drivers and (especially) civilian pilots (Siegel, 2005). Similarly, military training (particularly in connection with special forces) emphasizes preparation for performance under the pressure of sleep deprivation. Prisoner of war survivor training also...
sleep has an affect on memory, and how narcolepsy can affect memory. Finally, it will discuss how to avoid sleep deprivation. SLEEP DEPRIVATION AND MEMORY Sleep. We cannot live without it, but sometimes, it seems like we would like to. Sleep deprivation has become much more common in our hectic and demanding society. "Like the religious ascetics of medieval times, many people today regard sleep as 'time lost.' They regret that
(Harvard School of Public Health, 2013, p.1) Energy expenditure is decreased due to sleep deprivation because there is a decrease in physical activity as well as the body temperature being lowered. (Harvard School of Public Health, 2013, p.1) Summary of Literature The literature reviewed in this study has informed the study that children who sleep less hours each night are at a higher risk of becoming obese than children who sleep more
Therapeutic communities are important and valuable tools, but certainly not for all patients. Often, the community is made up of a certain ward or unit of the hospital, rather than the entire facility. Clearly, some patients, such as those suffering from serious debilitating diseases such as dementia or severe schizophrenia might not be physically or mentally able to exist in such a facility. However, for others, who have specific issues
Tom Shulich ("Coltish Hum") A Critical Comparison of Behavior Therapy and Rational-Emotive Therapy In this paper, I consider the benefits and drawbacks of behavior therapy and the cognitive therapy. These are talking therapies that now have over a half-century of application in clinical settings and are still used today in conjunction with, or as an alternative to, drug treatments of psychological disorders. I conclude that these therapies are still useful, though each
Sleep Deprivation on the Brain Studies on sleep deprivation continually display an inconsistent (negative) effect on mood, cognitive behaviour, and motor function as a result of a rising propensity for sleep as well as the destabilization of the wake condition. Unique neurocognitive domains such as executive attention, functioning memory, and conflicting higher cognitive behaviours are specifically apt to loss of sleep. In human beings, functional neurophysiological and metabolic studies prove
Objects are the same size, obviously, whether they are near or far, but our minds perceive size relative to surroundings. The dogs appear much larger the closer they get. They may seem huge to a person who is afraid of dogs. 3) Depressants, Stimulants, and Hallucinogens Depressants numb one's feelings. They act as anesthetic to one's nervous system. One loses energy, almost as if very fatigued. A person under the influence
