Should You Spit Phlegm Out?
Phlegm is a thick, sticky substance produced by the body to protect the lungs from irritants like dust, smoke, and mucus. It can be a nuisance, but it's important to know that spitting it out can actually be harmful.
Benefits of Swallowing Phlegm
- Protects the lungs: Phlegm contains antibodies and other protective substances that help fight off infection. Spitting it out removes these substances from the lungs, making them more vulnerable to infection.
- Moisturizes the throat: Phlegm helps keep the throat moist, which can prevent irritation and hoarseness.
- Prevents dehydration: Spitting out phlegm can lead to dehydration, especially if you're already dehydrated.
