A Brain Blogger news report examines the impact of marijuana on sleep.
Several research studies have unearthed the positive association between sleep and marijuana use. It is believed that marijuana usage in limited amounts can improve the quality of sleep.
There are five stages of sleep: four NREM (non-rapid eye movement) stages marked from 1 to 4 and a fifth stage called REM (rapid eye movement) sleep that is associated with dreaming. Stages 3 and 4 represent deep, slow-wave states of sleep, where the brain switches off almost completely and the heart rate and breathing decrease considerably. These states are restorative and refreshing. The four NREM and the REM stages occur in cycles throughout the period of sleep.
According to several studies, marijuana has been found to both induce sleep and increase the duration of Stage 4 sleep. These effects improve the overall quality of sleep in an individual.
