Higher ambient temperatures, particularly overnight, are significantly associated with an increased likelihood of acute work-related injuries across various worker demographics and occupational demands. This human factors research insight is drawn from a 2016 study published in Scandinavian Journal of Work Environment & Health. Using Case-crossover analysis, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Integrate thermal comfort and heat stress mitigation strategies into the design of work environments and job roles, especially for vulnerable worker groups.
Elevated ambient temperatures increase acute work-related injury risk by up to 1% per degree Celsius

Key Findings
- 01Significant positive associations between temperature and acute work-related injury were observed for younger workers (<25 years), with a 1% increase in injury odds for each 1°C rise in daily minimum temperature and a 0.8% increase for each 1°C rise in daily maximum temperature.
- 02Associations were also found between daily maximum temperature and injury risk for workers in the highest strength occupations and male workers.
- 03Daily minimum temperature was associated with injury risk for all cases combined, female workers, workers aged 25-35 and ≥55 years, 'light' and 'limited' physical demand groups, and those working in 'in vehicle or cab' and 'regulated indoor climate' environments.
Application
Design takeaway
Integrate thermal comfort and heat stress mitigation strategies into the design of work environments and job roles, especially for vulnerable worker groups.
How to apply
When designing workspaces or planning work schedules, consider the impact of ambient temperature on worker safety and performance, implementing cooling measures or adjusting work hours during heatwaves.
Project actions
- 01Consider how environmental factors like temperature could affect the usability and safety of your design.
- 02If your design is for an outdoor or potentially hot environment, research specific temperature thresholds for discomfort or risk.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Large dataset from workers' compensation claims provides a robust sample size.
- +Case-crossover design is effective for studying acute exposures and outcomes.
Limitations
The study's findings are specific to the Australian climate and may vary in different regions. The data is based on reported injuries, so underreporting could be a factor.
Reliability & validity
The study's reliability is supported by the large dataset and robust statistical methods. Validity is enhanced by the case-crossover design, which controls for time-invariant confounders, but may be limited by potential unmeasured confounders related to individual worker acclimatization or health status.
Think critically
How might the findings of this study be applied to the design of tools, equipment, or work processes to mitigate heat-related injury risks?
Design Principles
"Environmental conditions significantly influence human performance and safety; design interventions should proactively manage these conditions."
This research highlights a critical environmental factor impacting worker safety. Designers and safety professionals must consider thermal stress as a significant risk in occupational settings, especially as climate change leads to more extreme temperatures.
What This Means for Your Design
Working in hot weather makes people more likely to get hurt at work. Even a small increase in temperature can make a difference, especially for younger workers.

Paragraph starter
Research indicates that elevated ambient temperatures are associated with an increased risk of acute work-related injuries. For instance, a study found that for every 1°C increase in daily minimum temperature, the odds of injury increased by 1%, particularly affecting younger workers. This highlights the importance of considering thermal stress in the design of work environments and job roles to ensure user safety and well-being.
