Explanation:

🆕 New Concept Discovered: Physiological Effects of Smoking Cessation
How the body heals after quitting smoking

Step 1: Analyze the timeline of smoking cessation

When a person stops smoking, the body begins to repair itself almost immediately. Within the first 48 hours, several key physiological changes occur:

• 8 hours: Carbon monoxide levels in the blood drop, and oxygen levels return to normal.
• 24 hours: The risk of a heart attack begins to decrease.
• 48 hours: Damaged nerve endings start to regrow, which directly leads to an enhanced sense of smell and taste.

Step 2: Evaluate the given options

• a) decreased blood oxygen level: Incorrect. Blood oxygen levels actually increase and return to normal within the first 8 to 12 hours.
• b) improved ability to smell and taste: Correct. By 48 hours, nerve endings begin to regenerate, leading to a noticeable improvement in taste and smell.
• c) decreased circulation: Incorrect. Circulation begins to improve, not decrease, after quitting.
• d) increased sinus congestion: Incorrect. While some coughing may occur as the lungs clear out mucus, sinus congestion is not a standard positive physiological milestone of the first 48 hours.

Answer:

b) improved ability to smell and taste
