Which of the following is NOT a result of hypoxia in flight?

Hypoxia, or the state in which the body is deprived of adequate oxygen supply, has several well-established effects, especially relevant in flight situations. Among these is increased awareness, which is not a characteristic outcome of hypoxia. In fact, as oxygen levels drop, cognitive function can decline, leading to a reduction in awareness and alertness rather than an increase.

As the body experiences hypoxia, the brain and other vital organs do not receive sufficient oxygen, resulting in a range of symptoms that can escalate from mild impairments to severe consequences. Loss of consciousness is a critical risk in severe hypoxia, and impaired judgment can lead to poor decision-making under stress. Physical performance also declines, as muscles require adequate oxygen to function optimally. Therefore, the only outcome listed that does not correlate with the effects of hypoxia is increased awareness, which makes this the correct choice in the context of the question.
