4 Your Health: Tracking down the cause of a restless workforce

Posted: Updated:

Tucson- World Sleep Day is Saturday but getting some extra slumber this weekend is not going to help an already tired workforce.

A new survey from Career-Builder finds one in four workers feel they don't get enough sleep every night. And 60 percent said that lack of sleep has hurt their job performance.

But work may be what's costing them sleep. Nearly half of the surveyed workers said thinking about their job is what keeps them up at night.

Mice mimic behavior

If you've felt the urge to laugh, yawn, or scratch after watching someone else do it, you're not alone.

A new study involving mice shows the brain is responsible for contagious behavior.

Researchers found a specific area of the brain became active as mice watched other mice scratch and in turn scratched themselves.

When this brain activity was blocked, the mice stopped scratching. When they were again allowed to watch another mouse scratch they did the same.
