Work stress induced chronic insomnia in construction
Published in Imriyas Kamardeen, Work Stress Induced Chronic Diseases in Construction, 2021
Institute of Medicine (2006) suggested that sleep deprivation, particularly chronic insomnia, can have a wide range of effects on the cardiovascular, endocrine, immune and nervous systems. O’Connell (2017) provided a list of diseases that are caused by insomnia, namely: weak immune system, asthma attacks, seizures, inflammation, obesity, diabetes, high blood pressure, heart diseases and stroke. Khanijow et al. (2015) related sleep dysfunction with gastrointestinal diseases and reported strong relationships between sleep and diseases such as gastroesophageal reflux, peptic ulcer, irritable bowel syndrome, functional dyspepsia, inflammatory bowel, colorectal cancer and liver disease. Active Health (2019) alerted that chronic insomnia reduces life expectancy; the risk of early mortality is 97% higher in those who suffer from chronic insomnia.
Socio-emotional and Neurocognitive Effects of Sleep Loss
Published in Gerald Matthews, Paula A. Desmond, Catherine Neubauer, P.A. Hancock, The Handbook of Operator Fatigue, 2017
The effects of sleep deprivation on neurocognitive functioning are extensive, ranging from deficits in simple alertness, vigilance, and attention, to emotional processes such as mood, affective perception, and interpersonal responses to frustration, and even higher-order cognitive processes such as risk-taking, decision-making, and moral judgment. A common theme of the present chapter has been that sleep loss affects the normal functioning of prefrontal brain systems, which are critical for motivated and goal- directed behavior. While many other neurocognitive systems are undoubtedly affected by sleep loss as well, we have focused on the prefrontal attention and emotional–cognitive systems because these are likely to have particular relevance within the workplace and other operational environments.

Sleep deprivation is another determinant of errors. Researchers often evaluate sleep deprivation over long periods of wakefulness by not allowing the participants to sleep during the normal sleep cycle. Performance is evaluated over another 10–12 h of wakefulness, whereby the participants acquire 24–39 h of sleeplessness. Sleep deprivation tends to reduce our ability to think systematically and impacts our memory, perception, concentration, and reaction times. In fact, sleep loss deficits (20–25 h of wakefulness) are similar to having a blood alcohol content of 0.10% (Orzeł-Gryglewska, 2010). Yet, one does not have to experience total sleep deprivation to demonstrate negative behavioral effects. Individuals who were awake for 23 h and then allowed to sleep fewer than 5 h over an extended period experienced lower driving performance at any time of day during a 10-min driving simulation (Matthews et al., 2012).
Females exposed to 24 h of sleep deprivation do not experience greater physiological strain, but do perceive heat illness symptoms more severely, during exercise-heat stress

Sleep deprivation has been reported to contribute to exertional heat illnesses in a multitude of occupational literature (McDermott et al., 2007). Furthermore, 83% of HRI cases were related to a prior episode of sleep deprivation (3–4 h per night) (Rav-Acha, Hadad, Epstein, Heled, & Moran, 2004). Contributing factors to HRIs while sleep deprived include the larger (+0.7°C) exercising core temperature (Tre) (Sawka, Gonzalez, & Pandolf, 1984), impaired sudomotor function (reduced ability to dissipate heat through evaporation) (Fujita, Lee, Ismail, & Tochihara, 2003; Sawka et al., 1984) and increments in ratings of perceived exertion (RPE) and thermal sensation (TS) (Muginshtein-Simkovitch et al., 2015). While sleep is a naturally recurring state, characterised by circadian periodicity (García-García, Juárez-Aguilar, Santiago-García, & Cardinali, 2014), sleep loss (<6.5 h recommended per night) and/or deprivation (e.g., partial or full) disrupts the circadian rhythm and is highly prevalent among healthy adults and adolescents (Fullagar et al., 2015). Moreover, sleep deprivation is associated with health risks (e.g., increase diurnal blood pressure and cortisol levels) and cognitive impairments (e.g., decision-making, memory) (Short & Banks, 2014). Acute 24 h sleep deprivation observed during operational duties such as nursing, mining, aviation and trucking negatively influences cognitive function, which may influence, and potentially cause, several catastrophic incidents and accidents (Horne & Reyner, 1995).
Sleep-impaired emotional regulation, impaired cognition, and poor sleep health are associated with risky sleepy driving in young adults

The relationships between sleep-impaired emotional regulation and impaired cognition with risky sleepy driving behaviors is not well understood. Sleep deprivation leads to reductions of emotional regulation and impulse control, poorer cognition functioning, and increased irrational thought processes (Fuligni et al. 2017). Poor emotional regulation has also been linked with performing risky driving behaviors (Trógolo et al. 2014). Sleep restriction and poor sleep quality have been associated with impaired cognitive functioning as well as increased risk-taking propensity (DeMartini and Fucito 2014). As such, determining the associations of sleep-impaired emotional regulation and impaired cognition with risky sleepy driving behaviors is important.

Sleep deprivation has been shown to be a precursor to an array of adverse health outcomes, such as cardiovascular disease, substance abuse, metabolic diseases, and mental health illnesses.10 However, limited research has been conducted to determine whether EDS in firefighters is associated with higher rates of chronic disease and other adverse health outcomes. The goals of this study are to replicate previous studies by documenting the extent of EDS in full-time firefighters, and to extend the previous literature by identifying additional demographic and health factors associated with EDS in urban firefighters.
