For first responders, no two days are the same, but one thing remains constant: the pressure to make split-second decisions that can save a life. Whether responding to a car accident or mass casualty event, they must think and act quickly in moments when every second counts.

网红头条 research suggests that mental health challenges like depression, anxiety, and insomnia may significantly impact how well first responders can do their jobs.

Mahita Polineni, a third-year psychology student in KSU鈥檚 , is studying how these factors affect cognitive functioning including memory, concentration, and decision-making among emergency medical responders.

Polineni works with faculty mentor Kristin Horan, an associate professor of psychology and director of community engagement and outreach with the . Together, they analyzed national survey data to better understand the connection between mental health and performance. Their findings showed first responders who reported higher levels of depression, anxiety, or poor sleep were more likely to also report difficulties with focus, memory, and overall mental clarity.

鈥淏eing able to quickly assess a situation and make decisions is critical in these roles,鈥� Polineni said. 鈥淚f mental health or sleep is compromised, it can affect how effectively someone can respond in the field.鈥�

Polineni said one of the most striking findings in her research was how lack of sleep or insomnia affected performance.

鈥淲e already know sleep is important, but seeing how strongly it was connected to cognitive functioning in this population was surprising,鈥� she said. 鈥淚t showed just how essential rest is for people working in high-stress environments.鈥�

Polineni鈥檚 interest in the topic is deeply personal. As a high school student in Forsyth County, she trained as an emergency medical responder and worked alongside instructors who had careers in firefighting and emergency services. Through their experiences, she witnessed firsthand the emotional toll these professions can take.

鈥淭hey would go from one traumatic scene to another and then still have to go home and be present for their families,鈥� she said. 鈥淭here isn鈥檛 always space for them to process what they experience.鈥�

That constant exposure to trauma, combined with long shifts and limited recovery time, contributes to high rates of burnout among first responders. According to Polineni, many are forced to compartmentalize their experiences just to continue doing their jobs.

鈥淭his study is important because we depend on first responders to show up at their physical and mental best to avoid loss of property and life in dynamic and high-stress situations,鈥� Horan added. 鈥淵et, the job places them at heightened risk for sleep disruptions and mental health concerns.

She said the study highlights the need for agencies to provide more resources and support systems for first responders.

鈥淭he bottom line is, better cognitive performance benefits the first responder, their fellow teammates, and ultimately, the communities they serve," Horan noted.

Polineni suggests that emergency response agencies should consider expanding wellness programs to include mental health services and sleep support initiatives.

鈥淓ven small changes such as structured rest periods or access to counseling could improve both responder well-being and job performance,鈥� she said.

As she continues her research, Polineni hopes her work will bring greater awareness to the challenges first responders face and encourage meaningful change.

鈥淭hese are the people who show up for us in our most difficult moments,鈥� she said. 鈥淲e need to make sure we鈥檙e showing up for them, too.鈥�
