Cannabis boosts deep sleep but reduces REM sleep, affecting long-term well-being, a study finds.
A UT Dallas study of 60 adults with chronic pain found that cannabis use increases slow-wave sleep (SWS), the deep, restorative sleep stage tied to physical recovery, but reduces REM sleep, crucial for emotional regulation and memory.
Using 339 nights of in-home EEG data, researchers observed that while cannabis may temporarily boost SWS, this benefit may fade with long-term use.
The findings, published in Neurotherapeutics, reveal a trade-off in sleep architecture, highlighting the need for personalized approaches to pain and sleep management.
Though users report better sleep, objective data show significant shifts in sleep stages that could affect overall well-being.
