In circadian sleep disruption is a major consequence of both night shift and chronic to artificial at night (LAN) and has been shown to likelihood of hormone-dependent including and prostate in several cohort and case-control studies as well as in animal experiments. In addition, strong mechanistic evidence has been reported at the cellular and molecular levels in this regard. Thus, in the monographs of carcinogenic hazards to humans, the International Agency for Research on Cancer (IARC) classified shift work that involves circadian disruption in Group 2A, ‘probably carcinogenic to humans’ consecutively in 2007 and in 2019. This review aims to enable a better understanding of the complex relationship between circadian sleep distribution and cancer risk and addresses some precautionary measures to limit the risk of carcinogenesis in populations working in night-shifts and/or exposed to LAN.

With the rapid industrialization of modern society, people’s daily lives have changed. The invention of electricity has enabled the use of artificial light, which has consequently altered the industrial form and daily life [1]. The industrialization has increased both the types of occupations and the number of shifts available to workers. Shift work may be essential for security, infrastructure, and medical facilities, but in many cases, shift work is often done to increase productivity and convenience [2]. In Korea, approximately 10% of employees are shift workers. Among Korean shift workers, 50.4% work a rotating two-shift, 33.7% work a rotating three-shift, and 14.0% work a daily split shift [3].

Geriatric Sleep Medicine, also known as sleep medicine of old age, is medical field dealing with the prevention, diagnosis and treatment of sleep disorders in older adults. From the 2000s, through the pioneering approach of the two physicians, Dr. S. Hakki Onen (University of Lyon, France) and Dr. Fannie Onen (University of Paris, France), Geriatric Sleep Medicine was structured as a new clinical sub-specialty. These visionaries opened first Geriatric Sleep Medicine Centers dedicated to the prevention, diagnosis and treatment of sleep disorders of older patients with medical comorbid conditions and disabilities. For about two decades these centers encompass patient care, research, and educational missions. In 2006, the French Ministry of Health released a report on sleep including a Geriatric Sleep Medicine section co-authored by Onen F and Onen SH [1]. It was highlighted that sleep disorders in older people are usually unrecognized and/or untreated, contributing to a wide range of deleterious health and safety consequences including sedative drug abuse, cognitive impairment, cardiovascular complications, post-operative hazards, falls/fractures and increased mortality. Consequently, authors called for increased awareness among healthcare professionals about the physiology of healthy sleep and sleep disorders in older adults and the development and implementation of education programs to promote the early diagnosis and appropriate treatment of sleep disorders. The SFRMS (French Sleep Society) supported this call by organizing special sessions on sleep disorders and aging during its annual meetings.

Circadian rhythm refers to endogenous biological rhythm, which completes cyclic repetitions every 24 hours; the term originated from the Latin words circa, which means “around,” and dies, which means “day” [1,2]. Most organisms on the planet including human beings have evolved their own rhythmic programming of biological and behavioral outputs in response to these stimuli to maintain metabolic balance and promote survival [3,4]. Circadian rhythm helps our physiology to adapt to the environmental or behavioral changes in a time-of-day-dependent manner [5]. Beyond simply adapting to stimulus-response interaction, circadian rhythms are governed by an intrinsic molecular oscillator, the circadian clock [6]. Zeitgeber, literally meaning “time giver,” refers to any stimulus related to time cue from the external environment [1,6]. Our circadian clock constantly communicates with these zeitgebers to maintain circadian rhythm originally settled [1-6]. Without external stimulation, circadian clocks quite predictably control the daily timing of synthesis and release of most hormones [1,7]. In mammals, the circadian clock affects many aspects of the physiology including sleep-wake cycles, feeding-fasting cycles, and metabolic processes of the gastrointestinal tract, kidney, heart, and liver [8,9].

Sleep and stress are closely related phenomenon. Various sleep disturbances, including insomnia, may develop after stressful experiences or under stressful circumstances [1]. Individuals with underlying sleep problems are more vulnerable to depression and anxiety after a stressful event than are those without sleep problems [2-5]. The recent concept of sleep reactivity [6] describes the degree to which a stressor disrupts sleep [7]. Individuals with high sleep reactivity are more vulnerable to sleep disturbances after stress. Sleep reactivity is a predictive factor for insomnia [8], and of the various and heterogeneous etiologies of insomnia, it is thought to be the main cause of transient and chronic insomnia [9]. Insomnia is closely associated with depression and anxiety [10]; it is a diagnostic criterion for major depressive disorder and generalized anxiety disorder [11-13], and people with insomnia have more severe depression and anxiety symptoms than normal sleepers [14].

Obstructive sleep apnea (OSA) is a common disorder of middle-aged adults, affecting 4% of men and 2% of women [1]. The incidence of cardiovascular mortalities and morbidities such as hypertension, ischemic heart disease, arrhythmias, and stroke is higher in patients with OSA than in the general population [2]. OSA is characterized by recurrent upper airway obstruction. Patients with OSA experience intermittent hypoxia, leading to hypoxemia, hypercapnia, and increased sympathetic activation. Several studies have reported increased oxidative stress in patients with OSA [3-5]. Changes in blood oxygen saturation levels during sleep in OSA may result in the oxidant-antioxidant imbalance in favor of higher oxidants, depending on recurrent hypoxic events [6]. Increased generation of reactive oxygen species in vivo can lead to the depletion of one or more antioxidants, and the loss can be measured as an index of oxidative stress [7]. However, there are Total Oxidant and Antioxidant Status in Patients with Obstructive Sleep Apnea and the Effect of Continuous Positive Airway Pressure

Recently, growing evidence implies that circadian rhythm may influence and/or play a central role in psychiatric disorders, such as bipolar disorder [1,2], schizophrenia [3], and autism [4]. However, there is limited knowledge on the role of circadian rhythms in obsessive-compulsive disorder (OCD). Disruption of circadian regulation of body temperature and hormonal levels has been observed in those with OCD [5-7]. Difference in sleep behavior (i.e., reduced total sleep time, increased awakening after sleep onset, extended sleep onset latency) and in sleep architecture [i.e., decreased latency to the onset of rapid eye movement (REM) sleep and increased density of REM sleep] have been reported in OCD patients compared to healthy individuals [8-12]. Delayed bedtimes are also associated with increased OC symptoms [13]. Delayed sleep phase disorder is known to be more prevalent in severe OCD patients [14,15].

The axial rotation of the Earth, together with the light of the sun, generates 24-hour cycles of day and night, and this light-dark cycle is the basis of 24-hour circadian rhythms. Living organisms have their own endogenous circadian rhythms, also with a duration of approximately 24 hours, driven by environmental factors, especially light and darkness [1]. And it is widely known that circadian rhythms of mammals are regulated by an internal biological clock located in the suprachiasmatic nuclei (SCN) situated directly above the optic chiasm [2]. Maintaining the biological clock is crucial for coordinated function throughout the human body because this near-24-hour oscillations are found in essentially every physiological process in the human brain and body [3,4]. The period, phase and amplitude of circadian rhythms can be affected by circadian gene variants, light exposure, social cues, meal times and work schedules [5-8].

Epidemiology of insomnia in adolescents Insomnia symptoms are prevalent in both adults and children [1-4]. Female sex [4], low socioeconomic status [2], stressful life events [2], and poor general and mental health [5] are commonly identified risk factors. In particular, female sex is a consistent risk factor for insomnia in adult and elderly populations in terms of the higher prevalence, more persistent natural course [6], and more serious health-related repercussions [7]. For example, stronger impacts of insomnia symptoms on pain perception [8], increased cortisol awakening response [9], and resistant hypertension [10] were found in adult females when compared with adult males. Interestingly, most studies did not find any sex differences in insomnia in children [1,5,6].
