- Avoid eating 3 hours before bed
- Cut back on coffee, alcohol, chocolate, and spicy foods
- Elevate the head of your bed
- Try alkaline water or aloe vera juice to soothe irritation
2. Allergies (Seasonal or Indoor)
Pollen, dust mites, pet dander, or mold can trigger histamine release, leading to runny nose + postnasal drip.
✅ Solution:
- Use a HEPA air purifier in your bedroom
- Rinse sinuses daily with a neti pot (distilled water only!)
- Try quercetin (a natural antihistamine) or butterbur (studies show it rivals OTC meds)
3. Chronic Sinusitis or Nasal Inflammation
Even without a cold, inflamed sinuses can drain thick mucus down your throat—especially if you have a deviated septum or nasal polyps.
✅ Solution:
- Steam inhalation with eucalyptus oil (2–3x/day)
- Saline nasal spray (preservative-free)
- See an ENT if symptoms last >10 days
4. Dairy Sensitivity (Not Allergy!)
While dairy doesn’t cause mucus in most people, it can thicken existing mucus, making it feel more noticeable and sticky.
✅ Try this: Eliminate dairy for 2 weeks. If phlegm improves, you may be sensitive.
5. Dehydration or Dry Air
