I. Introduction
Sleep disorders are a range of conditions that disrupt the regular sleep cycle. Sleep disturbances are among the most prevalent clinical conditions encountered. Inadequate or non-restorative sleep can disrupt normal physical, mental, social, and emotional function. Sleep difficulties can have an impact on one’s general health, safety, and quality of life. A study found that insomnia patients’ quality of life was significantly reduced. It is crucial to emphasize that sleep disruption involves much more than an individual’s displeasure with failing to get enough sleep, or even the sense of being drowsy at the wrong time. Disrupted sleep is associated to a higher risk of a variety of disorders, including poor vigilance and memory, slower cognitive and physical reaction times, less enthusiasm, depression, insomnia, disorders of metabolism, obesity, immune dysfunction, and an increased risk of cancer.
