Sleep helps us recharge, but research suggests its impact is far larger than recharging our physical and mental batteries.
According to Patrick McNamara PhD, Shelby Harris PsyD, DBSM, and Dave Asprey, sleep is imperative to restoring cells, regulating metabolism, consolidating memory, and synchronizing the body’s internal clocks. REM in particular aided human cultural evolution, allowing our ancestors to make creative leaps by connecting disparate ideas. With this powerful ability, humanity was able to advance past lives of pure survival and into ones filled with art, science, and culture.
