The health insurance provider Aetna wants you to know the difference a good night’s rest makes, reports the Huffington Post.

A whopping 40 percent of Americans are getting less than their recommended nightly sleep — an issue the Centers for Disease Control and Prevention describes as a “public health problem.”

But more people and corporations  are increasingly waking up to the importance of a healthy night’s sleep. Leading the charge is the Hartford-based health insurance giant Aetna. Under the leadership of CEO Mark Bertolini, the company has made sleep health a major priority in the workplace — and now it will share the art and science of good sleep with the public.
