Download Abstract
Background: Heat injuries range from mild symptoms to life-threatening heat strokes,
which can cause disability and even might be fatal. Most cases occur during training,
and their incidence, particularly heat strokes, appears lower in combat, despite
limited adherence to heat-stress safety guidelines.
Objective: To assess whether the incidence of heat injuries and heat strokes is lower
in combat than during training, and to evaluate measures taken to reduce their
occurrence.
Methods: Structured debriefings were held with brigade and division medical
officers and the head of the Combat Fitness Division. Heat injury data from October
2023 through July 2024 were extracted from the IDF Medical Operations Center,
hospitalization monitoring system (“Qlik-Sense”), the Computerized Patient Record
(CPR), and the Institute of Military Physiology database.
Results: In the first months of combat, exertional heat strokes and moderate heat
injuries were reported less frequently than during training. Key factors included
maneuver characteristics, operational risk management, motivation and peer pressure,
the Logistics Directorate’s cooling-equipment program, and heightened awareness
among commanders and medical staff led by the Surgeon General HQ. Nonetheless,
debriefings highlighted that heat stress significantly impaired performance, causing
fatigue, reduced concentration, and discomfort. Existing cooling methods offered
partial relief, but more effective solutions are needed.
Conclusions: Heat injuries primarily happen during training, particularly during
marches. Training protocols should integrate combat-derived lessons, with emphasis
on awareness, early recognition, and treatment by commanders. Applying combatlevel cooling measures to training, alongside novel approaches, may reduce risk.
Findings are specific to Gaza operations and may not apply to other geographical
areas, where combat and logistical conditions differ.
