Minimal effect of alcohol ingestion on breathing during the sleep of postmenopausal women.
Eighteen asymptomatic postmenopausal women volunteered to ingest 2 ml of 100-proof vodka per kg of body weight in orange juice on one night and a placebo on another. Overnight sleep monitoring was performed immediately thereafter. Alcohol ingestion caused reduction in total sleep time from 329 to 281 minutes and a decrease in rapid eye movement sleep. There was no difference from placebo in the number of episodes of apnea or hypopnea, or in the frequency, length, or severity of oxygen desaturation. In contrast to the effects of alcohol ingestion in men, the effects on breathing and oxygenation are minimal during the sleep of women if this amount of alcohol is ingested.
