Preventing Heat Stress Using Data to Encourage Behavioural Change

Extreme heat is a growing concern for Australian industries, particularly for remote workers in mining, construction, oil and gas, and utilities. Traditionally, managing heat stress has relied on environmental readings and broad safety protocols. While helpful, these methods don’t reflect individual physiological responses to heat and that’s why personal heat stress monitoring should be considered.

Why Individualised Monitoring Matters

No two people respond to heat the same way. Factors like hydration, fitness, acclimatisation, and workload can influence how a person is affected by high temperatures. Personal heat stress monitors, worn as patches, smartwatches, or integrated body sensors, provide real-time insights into core body temperature, sweat loss, heart rate, and more. These devices give workers and supervisors live feedback, helping guide smarter decisions before heat-related symptoms escalate.Changing Behaviour Through Data

The real power of personal heat stress monitoring lies in how it influences behaviour. When workers receive alerts based on their individual responses to heat, they are more likely to:

• Take hydration and rest seriously
• Pause work before symptoms worsen
• Recognise how their body responds to different environments or tasks
• Engage more actively in managing their wellbeing
• Over time, these behavioural shifts create a safer, more self-aware workforce.

How Businesses Benefit

Encouraging proactive behaviour through technology doesn’t just protect workers, it also benefits your business.

Reduced incidents and absenteeism: Early detection means fewer heat stress-related medical events and reduced downtime.

Improved productivity: Workers who manage heat well maintain better energy, focus, and job performance.

Better compliance: With WHS regulations tightening and Safe Work Australia emphasising heat risk management, having documented data supports stronger compliance.

Data-driven improvements: Aggregated insights from wearables can help shape future scheduling, job rotation, and heat control strategies.

By embracing wearable technology, employers gain the tools to monitor workers more effectively, while empowering individuals to take ownership of their health. It marks a shift from reactive to proactive safety, with long-term benefits for people and productivity alike.
