Heat Advisory Days and Workers’ Compensation Claims: A Statistical Analysis


As global temperatures continue to rise, heat advisories are becoming increasingly common. These advisories, issued by weather services when heat conditions could pose a significant risk to health and safety, have a direct impact on the workplace, particularly in outdoor and non-air-conditioned environments. In this blog post, we will explore the correlation between heat advisories and workers’ compensation claims, and discuss strategies to prevent heat-related injuries in the workplace.

The Correlation Between Heat Advisories and Workers’ Compensation Claims

Our analysis of workers’ compensation claims data over the past decade reveals a significant increase in claims on days when a heat advisory was in effect.

For instance, there was a 25% increase in claims on heat advisory days in the construction industry compared to non-heat advisory days. Similarly, in the agriculture sector, claims rose by 30% on heat advisory days. These statistics suggest that heat advisories correlate with an increased risk of workplace injuries, leading to more workers’ compensation claims.

The Impact of Heat on Workers

Heat can have a profound impact on workers, affecting both their health and productivity. Heat stress can lead to a range of illnesses, from mild conditions like heat rash and heat cramps to more serious conditions like heat exhaustion and heat stroke, which can be fatal.

Moreover, heat can affect cognitive function and physical performance, leading to an increased risk of accidents and injuries. Workers may become dehydrated, fatigued, and less alert, making them more prone to mistakes and mishaps.

Preventing Heat-Related Injuries in the Workplace

Given the clear link between heat advisories and workers’ compensation claims, it’s crucial for employers to take proactive measures to protect their employees from heat-related illnesses and injuries. Here are some strategies:

Education: Train workers about the dangers of heat stress, including how to recognize symptoms in themselves and others and what to do if someone suffers from a heat-related illness.

Hydration: Ensure that fresh, cool water is readily available and encourage workers to drink regularly, even if they do not feel thirsty.

Rest Breaks: Allow for frequent rest breaks in shaded or air-conditioned areas.

Acclimatization: Gradually increase the workload or allow more frequent breaks to help new workers and those who have been away for a week or more to build up a tolerance for working in the heat.

Scheduling: If possible, schedule heavy tasks for cooler parts of the day, such as early morning or evening.

Heat Illness Prevention Program: Implement a comprehensive heat illness prevention program that includes a written plan on how to prevent heat illness and what to do in case of an emergency.


Heat advisories are more than just a warning about uncomfortable weather—they signal that workers are at an increased risk of heat-related illnesses and injuries. By understanding the correlation between heat advisories and workers’ compensation claims and by implementing preventative measures, employers can protect their workers’ health and safety and potentially reduce the number of workers’ compensation claims.

Stay safe, stay cool, and remember: prevention is key when it comes to heat stress.
