  • Alcohol can lead to fragmented sleep, frequent waking, and a decrease in REM sleep, which is the deepest stage of sleep. (shuteye.ai)
  • However, as alcohol levels in your body decrease, it transitions into a sedative, making you feel drowsy and facilitating sleep. (shuteye.ai)
  • Although further loss-of-function experiments are required, we hypothesize that this activation in DRN neurons may, at least in part, correlate with sleep dysregulation under a neuropathic pain-like state. (biomedcentral.com)
  • Drinking alcohol before bed can interfere with REM sleep, the most restful and restorative stage of sleep. (shuteye.ai)
  • It can lead to fragmented sleep, frequent waking, and reduced REM sleep, which is essential for restorative rest. (shuteye.ai)
