Should You Spit or Swallow Phlegm?

Phlegm is a thick, sticky substance produced by the body's respiratory system to trap and expel foreign particles, such as bacteria and pollution. While it's natural to produce phlegm, there's some debate about whether you should spit it out or swallow it.

Basic Concepts of Phlegm

Phlegm is composed of mucus, proteins, water, and cellular debris. It's produced by specialized cells in the respiratory tract and helps to:

Trap and expel foreign particles: Phlegm acts as a physical barrier, trapping bacteria, viruses, and other irritants in the respiratory tract.

Moisturize the respiratory tract: Phlegm keeps the lining of the respiratory tract moist, preventing it from drying out and becoming irritated.

Protect the lungs: By trapping and expelling foreign particles, phlegm helps prevent them from reaching the lungs, where they could cause infection or damage.

Spit or Swallow?

The decision of whether to spit or swallow phlegm depends on several factors, including its color, consistency, and the underlying cause of its production.

Swallowing Phlegm
