Can you tell me if it's unhealthy to swallow one's own phlegm during a cold or flu?
There is no definitive answer to this question, as opinions and beliefs seem to vary. Some people believe that swallowing phlegm can cause health problems, while others believe that it is not a big deal. However, there is some evidence to suggest that swallowing phlegm can be beneficial for the immune system, as it contains antibodies that can help fight off infections.
