Alcohol disrupts sleep architecture — reducing REM sleep, causing awakenings and worsening sleep apnea.
Quick Answer
Alcohol disrupts sleep architecture — reducing REM sleep, causing awakenings and worsening sleep apnea. Dr. Jitendra Prasad Yadav (NMC 8029, 15+ years of clinical experience) evaluates alcohol sleep disruption at Kathmandu Neurology Clinic & Cognitive Center, 117 Lal Durbar Marg, Kathmandu, Bagmati Province 44600, Nepal — evidence-based, medically reviewed.
Alcohol disrupts sleep architecture — it may help you fall asleep faster but reduces REM sleep, causes awakenings in the second half of the night, worsens sleep apnea and causes morning grogginess. Regular alcohol use significantly impairs sleep quality despite subjective feeling of better sleep.

Daytime fatigue
