newly released study from Indiana's Ball State University and posted by the Journal of Community Health says one-third of Americans get less than seven hours of sleep a night.

The study looked at more than 150,000 working adults between 2010 and 2018. When the study started, 30.9% reported they were not getting enough sleep. That number increased to 35.6% in 2018. 

Additionally, the study analyzed the professions where people were lacking sleep, like those in law enforcement, the military and health care, plus commercial drivers and people in production. 

“There is no definitive cause found for these trends in sleep duration in working American population,” said the study's author Jagdish Khubchandani. “We see the workplace is changing as Americans work longer hours, and there is greater access and use of technology and electronic devices, which tend to keep people up at night. Add to this the progressive escalation in workplace stress in the United States, and the rising prevalence of multiple chronic conditions could be related to short sleep duration in working American adults.”

Over-the-counter medication could also be a contributing factor, according to the study. 

Khubchandani says a lack of sleep is associated with numerous mental and physical health problems and added that employers should take responsibility for their employees and make sure to help those who suffer. 

Khubchandani says people who suffer from chronic sleep problems should look for help from medical professionals.
