The Connection Between Cold Weather And Catching A Cold

The video discusses new research on how cold weather affects the body's immune response, particularly in the nose, making us more susceptible to respiratory infections like COVID and flu. Dr. Benjamin Bleier explains that the nose plays a crucial role in fighting viruses by releasing vesicles that bind and kill viruses. Cold temperatures reduce the effectiveness of this immune response, leading to increased virus replication. This research challenges previous assumptions about why respiratory infections are more common in winter, suggesting that temperature changes, rather than indoor gatherings, are a key factor. The findings have implications for treatment and prevention, highlighting the importance of masking and potential new therapies.
