Introduction
Sleep is a state in which the body and mind are able to recover. Sleep is described as an innate and periodic state of rest in which consciousness of the outside world is suspended (Spriggs,2020). Biologically and behaviorally, sleep is an important component of human physiology, it represents one-third of the human lifespan. In general, human adults sleep between 7.5 and 8.5 hours a day (Alqudah et al., 2019).
Insomnia is characterized by persistent difficulty with sleep onset, duration, consolidation, or efficiency despite adequate opportunity and environments for sleep. Symptoms of insomnia may include daytime sleepiness, low productivity, memory lapses or concentration, mood swings, behavioral problems such as aggressive behavior, and predisposition to error (Spriggs,2020).
Insomnia can be classified as either a primary (unknown cause) or secondary (related to another medical condition). A variety of medical conditions can contribute to the development of secondary insomnia, including asthma,
chronic pain, diabetes, gastroesophageal reflux disease, obstructive sleep apnea, and other conditions that fall into this category (Qasim et al., 2021).
The effects of insomnia on human cognitive activities such as information processing, learning, and integrating intellectual records, all of which can contribute to poor academic achievement (Haile, Alemu and Habtewold, 2017; Alqarni, Alzahrani and Alsofyani, 2018).
A study found that Excessive Daytime Sleepiness (EDS) among a population of medical students was 93.2% (Alhazzani, Masudi and Algarni, 2018). Another study concluded that 73.7 % of students stated that sleep deprivation is caused by the demanding medical curriculum and the stress of final exams (Alqarni, Alzahrani and Alsofyani, 2018). Students with advanced academic achievement were more likely to sleep and get up earlier than those with lower performance (Haile, Alemu and Habtewold, 2017).
Medical students appear to be one group of people who are particularly sensitive to sleep loss, probably due to the long duration and high intensity of their studies (Azad et al., 2015).
