Our profession is responding to the challenge of a healthcare marketplace that increasingly clamors for more expertise to manage chronic conditions such as pain, IBS, headaches, anxiety and so forth, and demands accountability from practitioners. Sleep health services represent a key set of interventions well within our skill set as applied psychologists and readily adaptable to a variety of treatment settings.
Information about sleep abounds on the web, with numerous opportunities for all psychologists to become versed in the basics of sleep hygiene, insomnia treatment and circadian rhythms. Fellowships and training programs have been established around the country. We are immersed in a global, 24/7/365 world in which work-life boundaries are fluid, and demands are placed on people during what might have been traditional bedtimes. Electronic devices have proliferated, robbing people of sleep, illuminating their retina and stimulating their hypothalamus, all of which disrupts the circadian pacemaker. Nonetheless, we hear advertising messages about the brevity of life and that we should keep alert and conscious as much as possible in the 24-hour day. Have we figured out a way to eliminate the need to eat? I suspect we would have the same luck with sleep. Ironically, the sleep we do achieve may be deleteriously affected by the subtle but omnipresent “light fields” in which all urban dwellers reside. Such dispersed light pollution can suppress melatonin and fool the brain into thinking that we should be awake, active and cogitating. And more and more of us are living in the urban setting, replete with noise, fumes and activity, further impairing our ability to sleep in a consolidated, restorative fashion. It is in this environmental context that we can offer help to clients with insomnia, a widespread behavioral and public health issue in our society. Please refer to Morin, Bootzin, Buysse, Edinger, Espie & Lichstein, 2006. Well informed psychologists can debunk many of the myths about sleep that bedevil clients and perpetuate their sleeplessness.
There remain pockets of mental health professionals who regard sleep as a clinical issue outside their purview best left to “medical” practitioners. Nonsense. Sleep is a complex set of behaviors which can be readily quantified, as any sleep study data set can attest. Sleep outcomes (e.g., sleep onset latency, reducing nocturnal awakenings, self-rated sleep quality) can be operationally defined in care plans to satisfy the utilization review or treatment audit process. Traditionally, relaxation therapies have been implemented as a way to manage anxiety and thus facilitate sleep. Hypnotherapy has also been invoked. But the sleep function itself is typically bypassed in the everyday work of clinicians. We perform consultations or treatments in traditional wake time periods during the 24-hour clock. Performance fatigue, a ubiquitous problem vexing over-the-road truck drivers, nuclear power plant operators, military sentinels, pilots, ER workers, law enforcement and shift workers, has been studied extensively because of the huge personal and public safety considerations at play. The mindset of our profession was to buy into traditional concepts of psychiatric impairment, where the focus was presumably on daytime functioning and sleep would just be a background process that would take care of itself. Sleep issues do not always remit spontaneously. We now understand that there is a delicate interrelationship between how one functions during the day and night. The impact is bi-directional. Psychotherapy, behavior management, biofeedback, neuropsychological evaluations and so forth take place when a patient or client is presumably awake and alert, an assumption which may or may not be true. We have learned that the sleep-wake interface is more fluid and semi-permeable than first thought. We have all heard about dramatic cases of sleepwalking, sleepsex and sleepdriving. People have reportedly engaged in criminal behavior but later claim they were not cognizant or mindful of their actions. Micro-sleeping can occur during the middle of the day when a person is grossly sleep deprived. Sleep debt is cumulative, with insidious effects which cannot be rectified by one or two weekend nights of recovery sleep.
