Soldiers training on heavy artillery and athletes in contact sports are routinely exposed to repetitive mild shockwaves and injuries. Unlike someone who has just dodged a missile explosion or been smacked by a linebacker, they may feel little immediate impact.
The cumulative effects of these low-level blasts can, however, cause neurological problems such as sleep disorders and attention deficits, noted Bryan Pfister, director of New Jersey Institute of Technology’s Center for Injury Biomechanics, Materials and Medicine.
