A Brain Circuit May Build Muscle And Boost Cognition As We Sleep

"This balance is essential for growth, repair and metabolic health."

Most of us already know that getting enough sleep on the reg can reduce heart attack risk, make you more likely to exercise, and even help you live longer.

But working out exactly why that might be can prove difficult. In recent years, scientists have been looking more closely at the biological mechanisms behind sleep’s benefits.

And recently, a new paper published in the journal Cell identified a deep sleep circuit that might play a role in building muscle and improving our brain function.

The researchers discovered a feedback system that keeps certain hormones in check during sleep, too.

We now know more about how growth hormone is........
