Among physiological benefits, which is a benefit linked to humor?

• A. Increased respiration
• B. Improved respiration
• C. Decreased respiration
• D. No change in respiration

Answer: (B)

Humor tends to make breathing more efficient. When we laugh, we take deeper, more rhythmic breaths that engage the diaphragm and chest muscles, increasing tidal volume and improving ventilation. That means oxygen intake and carbon dioxide removal are enhanced, and overall breathing feels easier after the initial burst of laughter. So the beneficial physiological effect linked to humor is improved respiration. The other options describe changes in rate or no change, which don’t capture the positive, efficiency-focused impact humor often has on breathing.
