Introduction and objective: The health behaviours of professional drivers, including eating habits, directly affect their health, cognitive function, and consequently, road safety. Emotional eating, i.e., the consumption of food in response to stress and emotions, poses a particular threat to this occupational group. However, despite the growing interest in drivers’ health, comparative analyses between different groups of drivers in terms of eating behaviour remain scarce. Therefore, this study analyses differences in eating behaviour between urban and long-distance bus drivers and the impact of specific occupational demands on dietary choices. Material and methods: Urban (N = 229) and long-distance (N = 271) bus drivers from 14 Polish provinces were surveyed using three tools: the Healthy and Unhealthy Eating Behaviours Scale (HUEBS), Salzburg Stress Eating Scale (SSES) and Salzburg Emotional Eating Scale (SEES). Results: City drivers show healthier eating habits than long-distance drivers (p <.001). In stressful situations, long-distance drivers are more likely to reach for food (p =.011) and eat in response to anxiety (p =.001), despite experiencing lower levels of occupational stress. No significant differences between the driver groups were found in terms of emotional eating related to sadness, anger, and happiness. Moreover, a positive correlation was observed in the whole studied sample between unhealthy eating and stress eating (r = 0.24; p < 0.001). Conclusions: Occupational context significantly influences bus drivers’ eating behaviour, which provides a basis for targeted health-promoting interventions. Hence, the specific needs of various driver groups and the direction of further research are discussed.
When owls struggle at work: chronotype, burnout, and work ability in shift and non-shift employees

Evening chronotype has been linked to poorer occupational functioning, yet the mechanisms through which circadian preference relates to work ability remain insufficiently understood. This study examined whether job burnout functions as a psychological pathway connecting chronotype to work ability and whether this mechanism operates similarly in day workers and employees working shifts including night work. A cross-sectional Computer-Assisted Web Interviewing (CAWI) survey was conducted among 1,293 employed adults in Poland. Confirmatory factor analyses (CFA) and multi-group CFAs confirmed the factorial validity and full measurement invariance of all measures across both groups. Mediation models controlling for age and gender revealed a consistent mediation pattern in day and shift workers, with no significant between-group differences in path coefficients or indirect effects. Specifically, morningness was associated with lower burnout and higher work ability, burnout was strongly and negatively related to work ability, and the indirect effect of chronotype on work ability via burnout was significant, indicating partial mediation alongside a remaining direct effect. These findings demonstrate a general psychological mechanism linking chronotype to work ability that operates independently of formal shift work. The structural equivalence across groups suggests that chronotype-related vulnerability is not limited to shift work but may emerge under any rigid work schedule misaligned with individual circadian preferences. Chronotype-sensitive work arrangements and burnout-prevention strategies may therefore support sustainable work ability, particularly among employees with evening chronotypes.
Impact of Clothing Size on Thermal Insulation – A Pilot Study
(Sciendo, 2023-04-19) Młynarczyk, Magdalena; Orysiak, Joanna; Jankowski, Jarosław; Prus, Piotr; Central Institute for Labour Protection – National Research Institute, Warsaw, Poland
Thermal insulation may be influenced by the size of clothing and thus the volume of air gaps. The aim of this study was to determine the relationship between the size of outer wear clothing, and thus the indirect fit (the volume and size of air gaps), and thermal insulation in static and dynamic conditions. A set of underwear and two types of outerwear for workers of the energy sector and the chemical industry were selected for the study. Results showed that the value of thermal insulation (regardless of the type of outerwear) first increased with increasing clothing size.
