Deep sleep can calm, reset the anxious brain
Researchers have found that the type of sleep most apt to calm and reset the anxious brain is deep sleep, also known as non-rapid eye movement (NREM) slow-wave sleep, a state in which neural oscillations become highly synchronized, and heart rates and blood pressure drops.
A sleepless night can trigger up to a 30 percent rise in anxiety levels, researchers from the University of California said.
“We have identified a new function of a deep sleep, one that decreases anxiety overnight by reorganizing connections in the brain,” said study senior author Professor Matthew Walker.
