National study investigates sleep deprivation and firefighter health in the US

Study launched on firefighter sleep and health

The International Association of Fire Chiefs (IAFC) has reported that researchers have launched a national study into sleep deprivation among firefighters.

The Firefighter Investigative Research on Essential Zzz (FIREZzz) project is being run by the National Development and Research Institutes (NDRI) in partnership with Embry-Riddle Aeronautical University (ERAU).

According to IAFC, the study is open to both career and volunteer firefighters across the United States.

It aims to gather first-hand experiences on how long shifts, late-night calls and disrupted sleep affect firefighter health, safety and overall performance.

IAFC explained that the findings are intended to support practical recommendations to improve sleep hygiene across the fire service.

Research objectives and methodology

According to IAFC, the FIREZzz study will collect detailed accounts of sleep patterns, fatigue levels and related health outcomes.

It stated that participants will provide information on the main challenges they face in managing sleep while performing their duties.

The study also seeks to establish links between disrupted sleep and operational risks during emergency response.

The organisation reported that the data gathered will inform evidence-based strategies for improving firefighter wellbeing.

IAFC added that volunteer firefighters can invite their spouse or partner to participate in order to provide insight into the impact of firefighting duties on household sleep.

Confidentiality and participant protection

IAFC explained that the research is covered by a Certificate of Confidentiality issued by the National Institutes of Health (NIH).

It said this certification offers additional safeguards for the personal information of participants.

According to the association, only principal investigators and research assistants will have direct access to the submitted data.

It continued that certain oversight bodies may review study records to confirm proper research conduct, though confidentiality will be prioritised.

For volunteer firefighter households, IAFC noted that limited identifiers such as surname and the last four digits of a phone number will be collected to link firefighter and spouse responses.

Potential outcomes for the fire service

IAFC reported that the study aims to provide a clearer understanding of how chronic sleep disruption influences both short-term safety and long-term health among firefighters.

The organisation stated that results will be used to develop recommendations suited to real-world fire service operations.

It added that by documenting personal experiences, the project hopes to address challenges that standard medical evaluations may not fully capture.

The study is intended to strengthen occupational health policies and provide fire service leaders with data to guide operational decision-making.

Wider context of firefighter health

According to IAFC, firefighter health research has increasingly focused on the cumulative effects of occupational hazards, including exposure to carcinogens, cardiovascular stress and mental health demands.

It explained that disrupted sleep has been highlighted as a contributing factor to these risks, though systematic research has been limited.

The FIREZzz project is part of a wider effort to fill knowledge gaps and provide measurable data on how sleep patterns relate to overall firefighter wellbeing.

It aims to highlight how operational structures may be adapted to reduce health risks without compromising emergency response capability.

Relevance for fire and safety professionals

This research provides insight into the occupational health risks firefighters face from irregular sleep schedules and fatigue.

The findings may influence fire service leadership decisions about shift management and duty schedules.

For safety professionals, the study highlights how sleep deprivation interacts with other risk factors in frontline work.

The results could inform future training, policy development and health monitoring practices in fire and rescue services.

National study investigates sleep deprivation and firefighter health in the US: Summary

The International Association of Fire Chiefs (IAFC) has reported that researchers have launched a study into firefighter sleep deprivation.

The Firefighter Investigative Research on Essential Zzz (FIREZzz) project is run by the National Development and Research Institutes (NDRI) and Embry-Riddle Aeronautical University (ERAU).

The study will examine how disrupted sleep affects firefighter health, safety and operational performance.

Volunteer firefighters can invite spouses or partners to share how firefighting impacts household sleep.

The research is covered by a Certificate of Confidentiality from the National Institutes of Health (NIH).

Confidentiality protections will limit access to submitted data.

The findings are expected to inform recommendations for improving firefighter sleep hygiene.

The project is part of wider research on firefighter health in the United States.
