NEW YORK (TheStreet) -- Stress and the workplace, a tale as old as time. According to CNBC, the cost of U.S. worker disengagement is between $450 billion and $550 billion.

Fully 87% of workers feel disengaged, and 78% of companies classify stress as a top workforce health risk.

Arianna Huffington's new company, Thrive Global, sets out to combat the escalating epidemic of stress and burnout costing companies hundreds of billions of dollars.

"It has been escalating for a long time, and our relationship with technology has made it harder, because it's made it very hard for us to be able to take time off and recharge," Huffington said on CNBC's "Squawk Box."

Furthermore, the consequences are "horrific" she said. "The health care costs now are reaching the point where 75% are stress-related and preventable."

Not only does stress result in health problems, but it can prompt poor decisions as well, she added.

"Our company goes into corporations and deals with the culture through training and e-courses," Huffington said.
