This chapter explores the functions of the brain during REM sleep and deep sleep, including the activation of certain brain regions and the body's beneficial changes. It discusses the cleansing system in the brain that flushes out toxins during sleep and the therapeutic effects of sleep on mental health. The chapter concludes with a quote about the importance of sleep in bridging despair and hope.
What happens when we go to sleep? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly break down the mystery of why we sleep, time dilation in dreams, circadian rhythms, and sleeping in space with neuroscientist Matt Walker.
