Cold Weather Doesn't Cause Pneumonia, But Raises Risk: Doctor

• Pneumonia cases increase in winter, but cold weather doesn't directly cause the infection; it creates conditions that make people more vulnerable.
• Pneumonia is a lung infection caused by bacteria, viruses, or fungi, leading to inflammation and fluid buildup.
• Winter factors like dry nasal passages, increased indoor crowding, and prevalent viral infections (flu, COVID-19) heighten pneumonia risk.
• High-risk groups include older adults, young children, smokers, and individuals with chronic illnesses.
• Prevention involves vaccination (pneumococcal, flu), good hygiene, masks, healthy lifestyle, and avoiding smoking.

Why It Matters: It clarifies winter's indirect role in pneumonia, crucial for prevention.
