A new generation of hard hats is promising better protection against on-the-job concussions, also known as mild traumatic brain injuries.
The WaveCel hard hat is just the latest effort to update the products, known as industrial safety helmets, which brain injury experts say are overdue for an upgrade.
About one-fourth of all concussions among adults occur on the job, especially at construction sites. Falls, which often cause the head to turn or tip suddenly, are the most frequent cause. "But the construction workers I saw biking home today were wearing hard hats that are very similar to what I saw 10 to 15 years ago," he says.
The reason is that the brain is a bit like an egg yolk — a soft capsule surrounded by liquid, and contained inside a hard shell., the yolk inside will rupture even though the shell remains intact."They do a job at reducing force, so they serve a purpose," Madey says."But if they're not optimized to decrease the spin, they're not optimized to prevent injury."Madey and Bottlang initially founded WaveCel to make better sports helmets.
