Which factor does NOT affect hypoxia?

• A. Altitude
• B. Rate of Ascent
• C. Color of Clothing
• D. Medical Conditions

Answer: (C)

Hypoxia happens when tissues don’t get enough oxygen. Altitude directly affects this because the air has fewer oxygen molecules at higher elevations, so arterial oxygen content drops. The rate at which you ascend matters because rising quickly gives the body less time to acclimatize—breathing adjustments and other adaptations don’t keep up as well, increasing the risk of hypoxia. Medical conditions can also impair oxygen delivery, such as lung diseases that limit gas exchange or conditions that reduce the blood’s oxygen-carrying capacity. The color of clothing has no impact on any of these physiological factors; it doesn’t change oxygen availability, ventilation, or hemoglobin’s ability to transport oxygen. So the only factor among the options that does not affect hypoxia is the color of clothing.
