typically follow the example of their parents more than their friends. If someone stays awake for 48 consecutive hours, they could start to hallucinate. Other drugs, including the opioid buprenorphine, have also been used to alleviate symptoms of opiate withdrawal. The treatment of insomnia likely would include stress management techniques and changes in problematic behaviors that could contribute to insomnia (e.g., spending more waking time in bed). Recommendations like these have helped to decrease the number of infant deaths from SIDS in recent years (Mitchell, 2009; Task Force on Sudden Infant Death Syndrome, 2011). As part of treatment, the sleeping environment is often modified to make it a safer place for those suffering from RBD (Zangini, Calandra-Buonaura, Grimaldi, & Cortelli, 2011). Sleep regulationrefers to the brains control of switching between sleep and wakefulness as well as coordinating this cycle with the outside world. . Acetylcholine functions as a neurotransmitter in motor neurons. . Brainwave activity changes dramatically across the different stages of sleep. In such instances, REM rebound may actually represent an adaptive response to stress in non-depressed individuals by suppressing the emotional salience of aversive events that occurred in wakefulness (Suchecki, Tiba, & Machado, 2012). The amount of sleep we get varies across the lifespan. This chart illustrates the circadian change in body temperature over 28 hours in a group of eight young men. Parasomnias can occur in either REM or NREM phases of sleep. Sleep is also associated with the secretion and regulation of a number of hormones from several endocrine glands including: melatonin, follicle stimulating hormone (FSH), luteinizing hormone (LH), and growth hormone (National Institutes of Health, n.d.). Several of the nurses interviewed commented that their work schedules affected their relationships with their family. It is possible that even the processing of emotional information is influenced by certain aspects of sleep (Walker, 2009). Neurogenic shock is caused by damage to the central nervous system, usually a spinal cord injury. While the possession and use of marijuana remain illegal in many states, it is now legal to possess limited quantities of marijuana for recreational use in eleven states: Alaska, California, Colorado, Illinois, Maine, Massachusetts, Michigan, Nevada, Oregon, Vermont, and Washington. During this time, an individuals heart rate and respiration slow dramatically. His children and his wifes parents all agreed that Falater had an excellent relationship with his wife and they couldnt think of a reason that would provide any sort of motive to murder her (Cartwright, 2004). It is not uncommon for people suffering from undiagnosed or untreated sleep apnea to fear that their careers will be affected by the lack of sleep, illustrated by this statement from another patient, Im in a job where theres a premium on being mentally alert. Sleep-wake cycles seem to be controlled by multiple brain areas acting in conjunction with one another. Psychological dependence, or drug craving, is a recent addition to the diagnostic criteria for substance use disorder in DSM-5. 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). Our states of consciousness change as we move from wakefulness to sleep. They were ALL my fault. Our sleep-wake cycle, which is linked to our environments natural light-dark cycle, is perhaps the most obvious example of a circadian rhythm, but we also have daily fluctuations in heart rate, blood pressure, blood sugar, and body temperature. It is often prescribed for minor pain, and it is available over-the-counter in some other countries. High doses can cause death due to respiratory depression. When we do this, we often experience jet lag. Complications. We also alter our consciousness through the use of various psychoactive drugs. Some of these areas include the thalamus, the hypothalamus, and the pons. Other depressants include barbiturates and benzodiazepines. Again, this is an intuitive and appealing explanation for why we sleep. Recent research (Horikawa, Tamaki, Miyawaki, & Kamitani, 2013) has uncovered new techniques by which researchers may effectively detect and classify the visual images that occur during dreaming by using fMRI for neural measurement of brain activity patterns, opening the way for additional research in this area. Train your body to associate the bed with sleeping rather than other activities like studying, eating, or watching television shows. Therefore, the abuse potential of central nervous system depressants is relatively high. Unexplained hemorrhaging, bleeding or bruising. The fifth edition of theDiagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5) is used by clinicians to diagnose individuals suffering from various psychological disorders. 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. While there is tremendous variation in any given individuals sleep needs, the National Sleep Foundation (n.d.) cites research to estimate that newborns require the most sleep (between 12 and 18 hours a night) and that this amount declines to just 79 hours by the time we are adults. (a) This is a statue of a meditating Buddha, representing one of the many religious traditions of which meditation plays a part. They can be helpful for people working night shifts or for people affected by seasonal variations in light. Insleepwalking, or somnambulism, the sleeper engages in relatively complex behaviors ranging from wandering about to driving an automobile. 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 For individuals who are especially open to the power of suggestion, hypnosis can prove to be a very effective technique, and brain imaging studies have demonstrated that hypnotic states are associated with global changes in brain functioning (Del Casale et al., 2012; Guldenmund, Vanhaudenhuyse, Boly, Laureys, & Soddu, 2012). These individual differences in circadian patterns of activity are known as a persons chronotype, and research demonstrates that morning larks and night owls differ with regard to sleep regulation (Taillard, Philip, Coste, Sagaspe, & Bioulac, 2003). The different stages of sleep will be identified, and sleep disorders will be described. Guilleminault et al. While it is probably the most commonly used drug in the world, the potency of this particular drug pales in comparison to the other stimulant drugs described in this section. The brain waves associated with this stage of sleep are very similar to those observed when a person is awake, as shown inFigure 4.11, and this is the period of sleep in which dreaming occurs. This section will consider these questions and explore various explanations for why we sleep. During this time, there is a slowdown in both the rates of respiration and heartbeat. These synthetic drugs are so potent that even small doses can cause overdose and death. The FDAs 2013 recommendation for tighter controls on opiate prescriptions left many patients addicted to prescription drugs like OxyContin unable to obtain legitimate prescriptions. By analyzing dreams, Freud thought people could increase self-awareness and gain valuable insight to help them deal with the problems they faced in their lives. Hypnosis has also been used to draw out information believed to be buried deeply in someones memory. Nicotine exerts its effects through its interaction with acetylcholine receptors. Methamphetamineis a type of amphetamine that can be made from ingredients that are readily available (e.g., medications containing pseudoephedrine, a compound found in many over-the-counter cold and flu remedies). In some cases, users experience vivid visual hallucinations. People who suffer from insomnia might limit their use of stimulant drugs (such as caffeine) or increase their amount of physical exercise during the day. There is quite a bit of controversy within the scientific community as to the extent to which marijuana might have medicinal benefits due to a lack of large-scale, controlled research (Bostwick, 2012). While there are variations, there are four parts that appear consistent in bringing people into the state of suggestibility associated with hypnosis (National Research Council, 1994). (b) Heroin is cooked on a spoon over a candle. It is much more difficult to awaken someone from sleep during stage 3 than during earlier stages. 2. Marijuana may also have some promise in the treatment of a variety of medical conditions (Mather, Rauwendaal, Moxham-Hall, & Wodak, 2013; Robson, 2014; Schicho & Storr, 2014). Latent content, on the other hand, refers to the hidden meaning of a dream. In the therapeutic setting, a clinician may use relaxation and suggestion in an attempt to alter the thoughts and perceptions of a patient. Like many other stimulants, cocaine agonizes the dopamine neurotransmitter system by blocking the reuptake of dopamine in the neuronal synapse. Causes. Codeineis an opioid with relatively low potency. For instance, if a woman dreams about being chased by a snake, Freud might have argued that this represents the womans fear of sexual intimacy, with the snake serving as a symbol of a mans penis. These components include: These steps are conducive to being open to the heightened suggestibility of hypnosis. Meditative techniques have their roots in religious practices (Figure 4.21), but their use has grown in popularity among practitioners of alternative medicine. By the end of this section, you will be able to: Consciousnessdescribes our awareness of internal and external stimuli. Dreams and their associated meanings vary across different cultures and periods of time. Generally, alcohol is associated with decreases in reaction time and visual acuity, lowered levels of alertness, and reduction in behavioral control. Still, people experiencing opioid withdrawal may be given methadone to make withdrawal from the drug less difficult. After dinner, he prepared some materials to use in leading a church youth group the following morning, and then he attempted to repair the familys swimming pool pump before retiring to bed. Stimulantsare drugs that tend to increase overall levels of neural activity. The clock sets itself with light information received through projections from the retina. The following describe internal states of symptoms EXCEPT? Devices like this are designed to provide exposure to bright light to help people maintain a regular circadian cycle. In her case, the fact that her cataplexy was confined to the right side of her body was quite unusual. There is a trend that females report more somatic symptoms than males; thus, more females are diagnosed with somatic symptom disorder than males (APA, 2022). Comparative research indicates, however, that the relationship that exists between predatory risk and sleep is very complex and equivocal. (credit sleeping: modification of work by Ryan Vaarsi). Body temperature rises throughout the waking day, peaking in the afternoon, and falls during sleep with the lowest point occurring during the very early morning hours. Depending on the population and sleep disorder being studied, between 30% and 50% of the population suffers from a sleep disorder at some point in their lives (Bixler, Kales, Soldatos, Kaels, & Healey, 1979; Hossain & Shapiro, 2002; Ohayon, 1997, 2002; Ohayon & Roth, 2002).
