Which health effect is associated with carbon dioxide exposure?

• A. Respiratory problems
• B. It improves oxygen transport
• C. Causes hair loss
• D. Reduces blood pressure

Answer: (A)

Elevated carbon dioxide exposure primarily affects the respiratory system. When CO2 levels rise, the body responds by increasing breathing rate to try to expel the excess gas, but significant exposure can lead to respiratory distress and symptoms like shortness of breath, headaches, dizziness, and confusion as the blood becomes more acidic (respiratory acidosis). In enclosed spaces, CO2 can displace oxygen, increasing the risk of hypoxia and further breathing problems. This is why respiratory problems are the health effect most associated with CO2 exposure. The idea that CO2 improves oxygen transport isn’t correct, hair loss isn’t linked to CO2 exposure, and while severe exposure can affect circulation, the primary and most consistent association is with respiratory issues.
