Although the exact reason for the link between certain fields and sleep deprivation is unknown, researchers say they believe those in high-stress industries are more likely to bring that stress home with them, which affects sleep.
"If you are a police officer who just had a shooting encounter, it's hard for the brain to feel rested, and if that state is not achieved you don't sleep," researcher Jagdish Khubchandani said in an interview with NPR.
Researchers say adults who don’t get enough sleep have an increased risk of physical and mental health problems. Khubchandani said adults who get fewer than seven to nine hours of sleep are at a greater risk for obesity, heart disease, diabetes and anxiety.
"We're a very engaged 24-7 society and one of the first activities that gets curtailed is our sleep and many people are just not devoting enough time to sleep at nighttime," clinical psychologist Todd Arnedt told NPR.
To get a better night of rest, researcher Khubchandani advises certain lifestyle changes. He says things like a healthy diet, exercise and mediation can all help. Although, he added, the onus falls not only on the employees, but also on employers.
He said addressing stress in the workplace can help ensure workers are getting better sleep.
"Employers that are willing to help employees develop adequate sleep times may increase the probability of workplace productivity, reduction in employee health care costs, and improving workplace safety and health," the researchers wrote.
