Dedration can significantly impair cognitive performance.

Permanent brain damage typically begins after 4-6 minutes without oxygen, though some brain activity may persist slightly longer. This window is why immediate CPR and oxygenation are critical in cardiac arrest or drowning cases. The exact time varies by individual and temperature, but irreversible damage starts in this range.
