For military veterans with post-traumatic stress disorder, the bright fireworks of the holiday can take them to a dark place.
"Many of my patients, they don't look forward to it, to put it lightly. They kind of dread it, because they anticipate that there's going to be a lot of loud noises," said Dr. Hetty Eisenberg, the medical director of the PTSD clinical team at the Philadelphia Veteran's Affairs Medical Center.
She says firecrackers can have a number of negative results for those suffering from PTSD.
"Veterans will get triggered and will suddenly have reexperiencing symptoms. They'll have intrusive memories about things that have happened previously if they were in combat, or other situations or their past trauma," she explained.
She encourages friends, family and neighbors to be as considerate as possible when it comes to lighting off firecrackers.
This includes things like giving everyone notice of when they are about to be set off because you never know if a veteran is around.
"Provide as much support as you can, try to create a safe space," she added.
Dr. Eisenberg says part of that support includes talking to a veteran about how you can best help them.
