This podcast explains the different stages of sleep including non-REM sleep (which has three stages that become progressively deeper) and rapid eye movement (REM) sleep. Humans spend more time in REM sleep than any other primate, but sleep less overall than other primates.
The use of THC may disrupt REM sleep, leading to a rebound effect of increased REM sleep when usage is stopped. Alcohol is also shown to negatively impact the quality of sleep.
Sleep is often viewed as time wasted, especially among those focused on success in athletics or business. However, research shows that sleep is crucial for physical and emotional recovery, as well as cognitive function and productivity.
Sleep is divided into several stages and we cycle through them multiple times during a night's sleep. One of the main stages is called rapid eye movement (REM) sleep which is where we experience vivid dreams.
Learn about a spike in alertness and activity that occurs before bedtime, which can lead to anxiety for some people. Additionally, discover ways to improve the quality of your dreams, helping you to sleep more soundly.
