Military vets and fireworks: It's a complicated relationship

Author Shauna Springer (second row, far right) marches with military veterans in the 2018 Fourth of July parade in Danville, California.

Shauna Springer, the chief psychologist for Stella Center, is one of the nation's leading experts on PTSD and trauma. Known as "Doc Springer" in the military and veterans' communities, she has worked with hundreds of veterans over the past decade. Her latest book, "Warrior: How to Support Those Who Protect Us," published on May 18. The views expressed here are her own.

(CNN)Marine Corps veteran Brian Vargas is still triggered by the sound of fireworks.

A Purple Heart recipient, Vargas has endured over 200 medical procedures since his return from Iraq.
"There's just some sounds you'll never forget, like the sound of 5.56 and 7.62 rounds impacting all around you," said Vargas, now the manager for the Veterans Educational Transition Services Office and Veterans Resource Center at City College in San Francisco.
    "The sound waves of fireworks are so triggering to many veterans," Vargas said. "The impact of the emotional distress spills out into our lives, causing flashbacks and anger. We check and re-check our locks and stay up all night."
    While the Fourth of July can be likened to one of America's biggest street parties — at least in pre-pandemic times — our celebration of the sacrifices made by our nation's warriors can cause intensely painful trauma reactions for some who fight our wars.
