Is it unhealthy to swallow one's own phlegm during a cold or a flu? Are there any ill effects or benefits from swallowing or not swallowing phlegm?
Is it better to spit out phlegm instead of swallowing it?
It is generally recommended to spit out phlegm instead of swallowing it, as this can help reduce the amount of mucus in the lungs and throat. However, if you do swallow phlegm, it is generally not harmful and may even be beneficial for the immune system.
