Sleep is an essential part of life. Multiple studies have shown that a good night’s rest is crucial for optimal body and mind functionality. In today's fast-paced world, it can be difficult for some to fall asleep and, more importantly, into REM sleep. Rapid eye movement (REM) sleep is essential for learning and memory. During this deep sleep, your brain interprets and analyzes your experiences of the day and stores them in your long-term memory.
