Benefits of Spitting Phlegm

• Eliminates pathogens: Spitting phlegm helps expel bacteria and viruses from the respiratory tract. A 2019 study published in the Journal of Infectious Diseases found that spitting phlegm significantly reduces the transmission of respiratory infections.
• Reduces congestion: Phlegm can block the airways, causing congestion. Spitting it out helps clear the airways and improve breathing.

Benefits of Swallowing Phlegm

• Protects the throat: Phlegm contains proteins that protect the throat from irritation and infection. Swallowing phlegm helps lubricate and soothe the throat.
• Strengthens the immune system: Phlegm contains antibodies that help the immune system fight off infections. Swallowing phlegm exposes the immune system to pathogens, helping it build resistance.

Common Mistakes to Avoid

• Excessive spitting: Spitting phlegm too often can dehydrate the body and damage the throat.
• Swallowing thick, pus-filled phlegm: This type of phlegm may contain harmful bacteria that can cause infections in the digestive system.
• Ignoring persistent phlegm: Persistent phlegm could be a sign of an underlying medical condition that requires attention.

Success Stories

• A 2021 study published in the International Journal of Chronic Obstructive Pulmonary Disease found that regular phlegm expectoration significantly improved airway function in patients with chronic bronchitis.
• A 2018 study published in Pediatrics demonstrated that swallowing small amounts of phlegm helped strengthen the immune system and reduce the incidence of respiratory infections in children.
• A 2016 study published in the American Journal of Respiratory and Critical Care Medicine showed that phlegm aspiration could prevent lung infections in patients on mechanical ventilation.
