It’s Science 2018-11-10T05:00:00Z During REM sleep, the brain is highly active, while the body’s muscles are paralysed and heart rate increases, and breathing can become erratic. Sleep: how much do we really need? 2018-10-08T04:00:00Z But in recent decades, thanks in large part to the advent of brain-imaging machines, scientists have been able to establish that dreams themselves are essential to the benefits of REM sleep.
