About

The study explores how training for chemical and radiological hazards affects first responders. It describes the stress they face in dangerous situations, using heart rate variability to measure stress levels. The study found that anxiety decreased after training, but body awareness also dropped temporarily. No significant changes were observed in cognitive load or other heart rate measures. The research suggests regular practice can help reduce anticipatory anxiety before such simulations. It highlights the importance of understanding psychological and physiological responses to improve first responders' performance during real emergencies involving hazardous materials.
