How does altitude affect the way the brain is affected by alcohol?
Effects of alcohol are more pronounced at higher altitudes, e.g. 2 drinks at altitude may feel like 3 or 4 drinks on the ground. Alcohol causes histotoxic hypoxia, and when that’s combined with hypoxic hypoxia from lower air pressure, effects are compounded.
