Cause 1: Silent Reflux, the Invisible Enemy
Many people suffer from reflux without feeling burning. Instead of liquid acid, a microscopic vapor that contains a digestive enzyme called pepsin rises.
This enzyme can reach the throat, palate and even the nose, where it “falls asleep”.
When you consume something acidic (coffee, citrus fruits, sodas), that pepsin is reactivated and begins to irritate the mucous membranes. The body responds by producing large amounts of phlegm to defend itself.
What can help:
Gargling with water and a small amount of baking soda can neutralize that acidic environment and reduce irritation, especially in the morning and before bed.
Cause 2: Lack of hydration
Phlegm is made up of more than 95% water.
When the body is well hydrated, mucus is fluid and almost imperceptible. But with age, the feeling of thirst decreases and many people drink less water than necessary.
Mild dehydration can already make phlegm thick and sticky, making it difficult to eliminate.
Key habit:
Drink two large glasses of warm water as soon as you wake up, before any other drink.
Cause 3: The Myth of Milk (Protein A1)
It’s not always the milk itself, but the type of protein it contains.
Conventional cow’s milk usually has a protein called A1 beta-casein, which in many people generates intestinal and systemic inflammation.
This inflammation can manifest itself as excess phlegm in the throat and airways.
Simple test:
Eliminate traditional dairy products for 7 days and see if symptoms improve. Some people tolerate goat’s milk, sheep’s milk, or A2 products better.
Cause 4: Histamine-rich foods
Cured cheeses, sausages, red wine, fermented foods… they all contain histamine.
With age, the body produces fewer enzymes to break it down, which can lead to nasal congestion and thick phlegm the next day.
Strategy:
Reduce these foods at night and observe if the mornings become clearer.
Cause 5: Silent inflammation from excess sugar
The high consumption of sugar and refined flours feeds chronic inflammatory processes and alters the oral and respiratory flora.
This favors the constant production of phlegm and makes it difficult to eliminate.
A useful alternative for the evening is a warm drink with anti-inflammatory spices such as turmeric and ginger, using vegetable drink.
