Chapter 5: Indoor Air Pollutants and Toxic Materials Originally reported as a safe alternative to the known cancer-causing agents found in cigarettes, vaping is now known to be very dangerous and has led to serious lung disease and death in users. Once awakened from a narcoleptic attack, people report that they feel refreshed (Chokroverty, 2010). Some can cause heightened sensitivity to physical stimuli. This becomes a self-perpetuating cycle because increased anxiety leads to increased arousal, and higher levels of arousal make the prospect of falling asleep even more unlikely. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. While we have discussed the negative outcomes associated with sleep deprivation, it should be pointed out that there are many benefits that are associated with adequate amounts of sleep. Here are some tips to maintain healthy sleep: Aparasomniais one of a group of sleep disorders in which unwanted, disruptive motor activity and/or experiences during sleep play a role.

Brainwave activity changes dramatically across the different stages of sleep. Which of the following is true regarding patient adherence: d - all of the above (a - the average adherence rate for taking medication to treat acute illness is about 67%, b - adherence to taking medicine . Awareness of internal stimuli includes feeling pain, hunger, thirst, sleepiness, and being aware of our thoughts and emotions. Chronic insomnia is almost always associated with feeling overtired and may be associated with symptoms of depression. Stage 3is often referred to as deep sleep or slow-wave sleep because this stage is characterized by low frequency (less than 3 Hz), high amplitudedelta waves(Figure 4.10). Causes. If you lie down to take a nap and fall asleep very easily, chances are you may have sleep debt. In 2013, the U.S. Food and Drug Administration recommended tighter controls on their medical use. Awareness of external stimuli includes experiences such as seeing the light from the sun, feeling the warmth of a room, and hearing the voice of a friend. High doses can induce sleep, cause motor disturbance, memory loss, decreased respiratory function, and death. Opium, Heroin, Fentanyl, Morphine, Oxycodone, Vicoden, methadone, and other prescription pain relievers, Decreased pain, pupil dilation, decreased gut motility, decreased respiratory function. Heroin can be snorted, smoked, or injected intravenously. Manifest contentis the actual content, or storyline, of a dream. Again, this is an intuitive and appealing explanation for why we sleep. While "internal state" or impulsivity are terms more generally discussed in psychology or neuroscience, the concept is familiar to anyone. Two sleeping children are depicted in this 1895 oil painting titled. One complete menstrual cycle takes about 28 daysa lunar monthbut many biological cycles are much shorter. Aside from their utility as analgesic drugs, opioid-like compounds are often found in cough suppressants, anti-nausea, and anti-diarrhea medications. This theory is supported by Ernest Hilgards research into hypnosis and pain. Given the central role that sleep plays in our lives and the number of adverse consequences that have been associated with sleep deprivation, one would think that we would have a clear understanding of why it is that we sleep. Thus we sleep in safe areas to reduce the chance of harm. Upset stomach and vomiting. Several of the nurses interviewed commented that their work schedules affected their relationships with their family.
Shock: Signs, Causes, and Types - Healthline Individuals who do rotating shift work are also likely to experience disruptions in circadian cycles. Complete the following multiple choice quiz covering chapters 1, 6, and 9. Sleep deprivation, in general, is associated with a number of negative consequences (Brown, 2012). It is much more difficult to awaken someone from sleep during stage 3 than during earlier stages. Insleepwalking, or somnambulism, the sleeper engages in relatively complex behaviors ranging from wandering about to driving an automobile. Yarmila Falaters body was found in the familys pool with 44 stab wounds. Treatment. This causes blood vessels to dilate, and the skin may feel warm and flushed. For example, people who undergo chemotherapy will often be prescribed marijuana to stimulate their appetites and prevent excessive weight loss resulting from the side effects of chemotherapy treatment. Like many other stimulants, cocaine agonizes the dopamine neurotransmitter system by blocking the reuptake of dopamine in the neuronal synapse. We spend approximately one-third of our lives sleeping. 1. While medical marijuana laws have been passed on a state-by-state basis, federal laws still classify this as an illicit substance, making conducting research on the potentially beneficial medicinal uses of marijuana problematic. For example, most people sleep during the night and are awake during the day. There may also be differences in both brain structure and function in infants that die from SIDS (Berkowitz, 2012; Mage & Donner, 2006; Thach, 2005). Some of these approaches, such as using a bright light as shown inFigure 4.4, have been shown to alleviate some of the problems experienced by individuals suffering from jet lag or from the consequences of rotating shift work. It is possible that even the processing of emotional information is influenced by certain aspects of sleep (Walker, 2009). Guilleminault et al. One of the most common treatments for sleep apnea involves the use of a special device during sleep. In other words, dreaming involves constructing a virtual reality in our heads that we might use to help us during wakefulness. Just as bears hibernate in the winter when resources are scarce, perhaps people sleep at night to reduce their energy expenditures. In Falaters case, a jury found him guilty of first degree murder in June of 1999 (CNN, 1999); however, there are other murder cases where the sleepwalking defense has been used successfully.

MDMA (3.4-methelynedioxy-methamphetamine, commonly known as ecstasy or Molly) is a mild stimulant with perception-altering effects. (Jayanthi & Ramamoorthy, 2005; Rothman, Blough, & Baumann, 2007). These symptoms include fatigue, sluggishness, irritability, andinsomnia(i.e., a consistent difficulty in falling or staying asleep for at least three nights a week over a months time) (Roth, 2007). Some research suggests that sleep deprivation affects cognitive and motor function as much as, if not more than, alcohol intoxication (Williamson & Feyer, 2000). We also alter our consciousness through the use of various psychoactive drugs. Restless leg syndrome is quite common and has been associated with a number of other medical diagnoses, such as chronic kidney disease and diabetes (Mahowald & Schenck, 2000). This campaign is sponsored in part by the National Institute of Child Health and Human Development. In general, these drugs are not thought to possess the same sort of abuse potential as other classes of drugs discussed in this section. Users often consume the drug every few hours across days-long binges called runs, in which the user forgoes food and sleep. More specifically, homeostasis is the body's tendency to monitor and maintain internal states, such as temperature and blood sugar, at fairly constant and stable levels. Rotating shift work has pervasive effects on the lives and experiences of individuals engaged in that kind of work, which is clearly illustrated in stories reported in a qualitative study that researched the experiences of middle-aged nurses who worked rotating shifts (West, Boughton & Byrnes, 2009). . Despite recent changes in laws designed to make obtaining pseudoephedrine more difficult, methamphetamine continues to be an easily accessible and relatively inexpensive drug option (Shukla, Crump, & Chrisco, 2012). The different stages of sleep will be identified, and sleep disorders will be described. Some sleep-deprived individuals have difficulty staying awake when they stop moving (for example sitting and watching television or driving a car). The participant is made comfortable and is directed to be relaxed and sleepy. As a result, many scientists have urged the federal government to allow for relaxation of current marijuana laws and classifications in order to facilitate a more widespread study of the drugs effects (Aggarwal et al., 2009; Bostwick, 2012; Kogan & Mechoulam, 2007). Once she was able to limit her use to less than 12 ounces of soda a day, both her mental and physical health gradually improved. Some people also experience altered states of consciousness through meditation, hypnosis, or alcohol and other drugs. Typically, individuals suffering from night terrors will fall back asleep again within a short time. If we have biological rhythms, then is there some sort ofbiological clock? This chapter will discuss states of consciousness with a particular emphasis on sleep. He suffered from no apparent anatomical brain anomalies or psychological disorders. Natural opioids, calledopiates, are derivatives of opium, which is a naturally occurring compound found in the poppy plant. Cognitive-behavioral therapyis a type of psychotherapy that focuses on cognitive processes and problem behaviors. The first three stages of sleep are NREM sleep, while the fourth and final stage of sleep is REM sleep. The early portion of stage 1 sleep producesalpha waves, which are relatively low frequency (813Hz), high amplitude patterns of electrical activity (waves) that become synchronized (Figure 4.8). Adepressantis a drug that tends to suppress central nervous system activity. People who suffer from this disorder can injure themselves or their sleeping partners when engaging in these behaviors. d. both b and c. 2. During sleep, the pituitary gland secretes both FSH and LH which are important in regulating the reproductive system (Christensen et al., 2012; Sofikitis et al., 2008). Thepineal gland, an endocrine structure located inside the brain that releases melatonin, is thought to be involved in the regulation of various biological rhythms and of the immune system during sleep (Hardeland, Pandi-Perumal, & Cardinali, 2006). (a) A period of rapid eye movement is marked by the short red line segment. c. Rotating shift workrefers to a work schedule that changes from early to late on a daily or weekly basis. Some circadian rhythms play a role in changes in our state of consciousness. b. life expectancy has reached a new high. Parasomnias can occur in either REM or NREM phases of sleep. As an individual continues through stage 1 sleep, there is an increase in theta wave activity. Brainwave activity changes dramatically across the different stages of sleep. While individuals suffering from sleep apnea may not be aware of these repeated disruptions in sleep, they do experience increased levels of fatigue. Some research suggests that species that face higher predatory risks sleep fewer hours than other species (Capellini et al., 2008), while other researchers suggest there is no relationship between the amount of time a given species spends in deep sleep and its predation risk (Lesku, Roth, Amlaner, & Lima, 2006). D) the demographic characteristics of the person C) the severity and duration of the problem. Some forms of psychotherapy, such as cognitive-behavioral therapy, can help sufferers of insomnia. Vaping uses battery-powered devices, sometimes called e-cigarettes, that deliver liquid nicotine and flavorings as a vapor. Understanding the impact of sleep on cognitive function should help you understand that cramming all night for a test may be not effective and can even prove counterproductive. Furthermore, these types of behaviors ultimately disrupt sleep, although affected individuals have no memories that these behaviors have occurred (Arnulf, 2012). There are two types of sleep apnea: obstructive sleep apnea and central sleep apnea. In the therapeutic setting, a clinician may use relaxation and suggestion in an attempt to alter the thoughts and perceptions of a patient. In her case, the fact that her cataplexy was confined to the right side of her body was quite unusual. Methamphetamine in its smokable form, often called crystal meth due to its resemblance to rock crystal formations, is highly addictive. Elements that are known to make PTSD more likely are the following: Perceived life threat Personal injury Interpersonal violence, particularly perpetrated by a caregiver Past and present vulnerability, including genetics, childhood trauma, insufficient emotional support, concurrent causes of stress Example: Childhood abuse and rape Opioid addiction reached crisis levels in the United States such that by 2019, an average of 130 people diedeach dayof an opioid overdose (NIDA, 2019). Using crystal meth poses a number of serious long-term health issues, including dental problems (often called meth mouth), skin abrasions caused by excessive scratching, memory loss, sleep problems, violent behavior, paranoia, and hallucinations.
