Study warns of cardiovascular risks of drinking alcohol and sleeping in conditions comparable to airplane flight
Drinking alcohol and sleeping in hypobaric conditions - such as those of an aircraft cabin - could be a risk to cardiovascular health, a study warns. Researchers compared a group of 23 people sleeping in a laboratory with another group of 17 people sleeping in a high-altitude chamber, replicating conditions at about 2,400 metres above sea level. The combination of alcohol consumption and hypobaric hypoxia during the simulation "reduced sleep quality, challenged the cardiovascular system and led to extended duration of hypoxaemia," the authors state in the journal Thorax.
