Cold Weather and Respiratory Illness: Understanding the Real Connection
• Cold weather doesn't directly cause respiratory illnesses, but it creates conditions that make people more susceptible.
• Cold, dry air allows viruses to survive longer and weakens immune defenses in the nose and throat.
• Spending more time indoors and reduced sunlight exposure during winter increase the risk of virus transmission.
