Which statement is true about the effects of altitude on alcohol?

At higher altitudes, the effects of alcohol are indeed enhanced due to a combination of physiological factors. As altitude increases, the partial pressure of oxygen decreases, which can lead to symptoms of hypoxia (insufficient oxygen in the body). This hypoxic environment can exacerbate the effects of alcohol, making one feel intoxicated more quickly and intensely than at sea level.

The body’s response to alcohol is influenced by the oxygen levels available, and with lower oxygen, a person might experience dizziness, impaired motor skills, and decreased cognitive functioning more acutely. This interplay between alcohol consumption and altitude can pose significant risks, especially in contexts such as flying, where both alcohol and high altitudes can impair judgment and physical abilities.

Other options suggest that altitude has either a negligible effect or a diminishing effect on alcohol, which neglects the significant impact of reduced oxygen availability on the body’s alcohol metabolism and overall functioning at high altitudes.
