Body temperature and oxygenation levels significantly influence human cognitive performance, as evidenced by studies showing that thermal stress and hypoxia alter executive function, reaction times, and working memory.

The analysis

The retrieved literature consistently supports the claim that physiological stressors such as altered oxygenation and thermal stress impact cognitive functions like executive control, working memory, and processing speed. Papers 0, 2, and 4 provide direct experimental and clinical evidence linking temperature and oxygen variations to cognitive changes. No papers refute the claim.
