Does spitting out phlegm help you get better?
I'm curious to know if spitting out phlegm really does help one get better when they're feeling ill. Many people seem to do it instinctively when they're coughing or have a sore throat, but is there any scientific evidence to support this practice? Could it actually be beneficial in some way, or is it just a habit that people have developed over time? I'd appreciate any insights or explanations you might have on this topic.
