Sleep research has grown over the past decades and investigators are deeply involved in
studying sleep and its impact on human health and body regulation. Despite the understanding
that insufficient sleep is strongly linked to the development of several disorders, unsatisfactory sleep
exposes health and safety to innumerous risks. The present study aims to review and analyze the
main results of clinical trials, registered at ClinicalTrials.gov and ICTRT databases, and developed
construct strategies to improve sleep quality on firefighters and enhance professionals’ sleep and
health conditions. The protocol was registered in PROSPERO under number CRD42022334719. Trials
registered between first registry and 2022 were included. We retrieved 11 registered clinical trials;
seven met eligibility criteria and were included in the review. A relation between sleep disorders,
shift work, and occupational health problems was found, and retrieved trials showed that sleep
education programs can improve sleep quality and sleep hygiene. Science has already recognized
sleep’s importance for metabolic functioning and survivorship. Nevertheless, it continues to play a
major role in discovering methods to diminish the problems faced. Strategies contemplating sleep
education, or intervention, should be presented to fire services to tackle this problem and promote
healthier and safer environments.
