Military heatstroke cases still on the rise as units push tech, awareness
BLUF – New Defense Health Agency data show military heatstroke cases increased for the second consecutive year in 2025 despite expanded prevention efforts, with experts suggesting that improved recognition, diagnosis, wearable monitoring technology, and greater awareness may be identifying more severe cases earlier rather than indicating prevention programs are failing. For Navy Medicine, the findings reinforce the importance of environmental medicine, corpsman and medic training, rapid recognition and treatment of exertional heat illness, and continued investment in wearable technologies and evidence-based prevention strategies to reduce heat-related injuries while maintaining operational readiness.
