Recently, a research team at Harvard Medical School discovered a striking new discovery: when pathogens enter the body through the nose, the nasal cavity will quickly release a special microscopic bubble that can surround and attack bacteria and play a certain protective role. However, this protective mechanism weakens in cold weather, increasing the risk of upper respiratory tract infections.
According to the researchers, tiny nasal bubbles are made up of cell secretions in the nasal cavity, which are able to quickly recognize and surround bacteria, thus preventing them from further invading the body. However, when the ambient temperature drops, so does the temperature inside the nose, which leads to a weakening of the protective mechanism of the tiny bubbles in the nasal cavity. As a result, our noses are more susceptible to bacterial attacks in cold weather, increasing the risk of infection.
In addition, researchers have also found that cold weather may suppress the body's immune system, further increasing the risk of infection. The immune system plays a key role in fighting off pathogens, however, in cold environments, the function of the immune system may be suppressed, making the body more susceptible to infection.
More worryingly, studies have also shown that the virus becomes more transmissible in the air during the cold season. This may be due to the fact that people spend more time indoors and poor air circulation, which provides favorable conditions for the spread of the virus. Therefore, in cold weather, we need to pay attention not only to our own warmth, but also to improve air circulation to reduce the risk of virus transmission.
For this finding, the Harvard Medical School research team said that it provides clues to a deeper understanding of the mechanism of infection and also reminds us to take precautions in cold weather. They suggest that during the cold season, we should take care to keep our nasal passages warm and reduce the risk of infection by wearing masks, washing hands frequently, and avoiding prolonged exposure to cold.
In addition, the research team said that they will continue to delve into the protective mechanisms of tiny nasal bubbles, hoping to find more effective ways to prevent infection. They believe that through further research, we can better understand how the body's immune system works, providing stronger support for the prevention and treatment of infections.
In conclusion, the latest findings from Harvard Medical School reveal the protective mechanisms of tiny nasal bubbles and the impact of cold weather on the risk of infection. This finding reminds us to take precautions during the cold season to keep our nasal passages warm and reduce the risk of infection. Hopefully, future research will provide us with more important clues about the mechanism of infection and provide more effective protection for human health.
