The Impact of Exceeding Permissible Work Hours on Health

Under current Polish labor legislation, the weekly working time—including any overtime—must not exceed 48 hours within the designated accounting period. Adherence to these regulations serves not only to alleviate fatigue but also to mitigate the risk of developing a wide spectrum of physical illnesses and psychological disorders. Excessive work demands exert detrimental effects on both physical well-being and mental equilibrium, ultimately compromising overall quality of life. Comparative European research (Parent-Thirion et al., 2007) reveals that Poland ranks fourth in the proportion of workers exceeding 48 hours per week, trailing only Turkey, which holds the highest position in this concerning classification.

The chronic exceedance of standard working hours exerts a profound, multifaceted impact on an individual’s psychological well-being. Persistent exhaustion, stemming from prolonged occupational engagement, frequently precipitates a decline in emotional stability and overall subjective well-being. Empirical evidence consistently demonstrates that individuals exceeding 48 weekly working hours exhibit diminished cognitive performance and reduced productivity. As early as the 1990s, cumulative associations were identified between excessive work durations and an elevated susceptibility to depressive episodes and chronic insomnia—findings corroborated by meta-analyses, including a study by K. Sparks et al. (1997), which examined the correlation between work hours and participants’ self-reported psychological comfort. Parallel dependencies were documented among military personnel, where intense temporal demands coincided with symptoms of anxiety disorders and depressive states (Bliese & Halverson, 1996). Contemporary research not only replicates these conclusions but also expands them to include additional risk factors: prolonged exposure to time-related pressure not only escalates stress levels (Park et al., 2020) but also disrupts the body’s regenerative processes. Individuals employed in shift-based systems (e.g., 15.5-hour shifts) experience chronic sleep deficits, impaired nocturnal recovery quality, and persistent fatigue, all of which detrimentally affect overall quality of life (Kecklund, 2001). Sustained occupational stress, arising from perpetual workload excess, constitutes a significant risk factor for the development of severe psychological disorders, including neuroses and major depressive episodes. On a somatic level, chronic activation of the hypothalamus-pituitary-adrenal (HPA) axis—triggered by stress—predisposes individuals to gastrointestinal pathologies (e.g., ulcerative gastritis), hypertensive disorders, and cardiac arrhythmias, further compromising overall health status.

Prolonged working hours exert a substantial detrimental effect on the quality of life within a social framework, progressively undermining both familial bonds and interpersonal connections. The persistent absence of leisure time frequently results in the gradual exclusion of individuals from their immediate social circles, a phenomenon attributable not solely to temporal constraints but also to deteriorating mental well-being—encompassing chronic fatigue, diminished mood, and a pervasive sense of exhaustion. Empirical research, including the 2009 study by D. Żołnierczyk-Zreda, has demonstrated a significant correlation between one spouse’s excessive occupational demands and the manifestation of stress-related symptoms, depressive episodes, and anxiety disorders in their partner, thereby illustrating the far-reaching negative impact of sustained overwork on the dynamics of interpersonal relationships.

Prolonged working hours exert a substantial impact on both mental and physical well-being. According to a 2020 report by the World Health Organization (WHO) and the International Labour Organization (ILO), excessive work hours in 2016 contributed to 745,000 fatalities resulting from stroke and ischemic heart disease—a 29% increase compared to the year 2000. Men are disproportionately affected, accounting for 72% of cases. Research, including a 2006 study by H. Yang et al., has established a correlation between extended work schedules and the development of hypertension. Furthermore, time constraints often lead to reliance on ultra-processed foods high in trans fats, sodium, and refined sugars. Fatigue from overwork elevates the risk of workplace injuries, particularly in occupations demanding sustained attention, such as drivers or machine operators. Chronic time scarcity also promotes unhealthy lifestyle habits, including tobacco use, excessive alcohol consumption, and physical inactivity, thereby increasing susceptibility to non-communicable diseases such as cancer, obesity, type 2 diabetes, and atherosclerosis. Nutritional deficiencies—such as inadequate calcium or iron intake—may result in osteoporosis or anemia, while sedentary behavior contributes to weight gain and associated conditions like hypertension and metabolic disorders.

Specialists from the World Health Organization emphasize the urgent need for behavioral adjustments among both employees and managerial staff within companies, as this plays a pivotal role in safeguarding the well-being of the active workforce. A cornerstone of this approach involves strict adherence to guidelines governing the maximum permissible weekly working hours to prevent adverse physical and mental health outcomes. Additionally, the WHO highlights the importance of equitably distributing workloads among team members, which fosters a balanced work environment and significantly mitigates the risk of occupational burnout.

A substantial body of peer-reviewed research and comprehensive meta-analyses consistently demonstrates that the chronic exceedance of recommended working hour thresholds exerts profound detrimental effects on both psychological equilibrium and physiological well-being. Rigorous adherence to prescribed weekly work-hour limitations has been empirically shown to substantially diminish the likelihood of developing severe health conditions, including but not limited to major depressive episodes of varying severity, generalized anxiety disorders, chronic arterial hypertension, and cerebrovascular incidents—all of which are frequently associated with long-term disability or fatal outcomes.
