"During #REM_sleep an #extraordinary_thing happens. One of the stress-related chemicals in the brain, #noradrenalin, is switched off. It's the only time, day or night, this happens. It allows us to remain calm while our brains reprocess all the experiences of the day, helping us come to terms with particularly emotional events."
