Nasal congestion at night from allergies, especially triggered by certain juices, can be managed with some practical self-care steps to ease your breathing and reduce symptoms.

1. Identify and Avoid Triggers

   • Some juices or their ingredients might worsen your allergies; try to avoid drinking juice in the evening or note which types cause symptoms and limit those.

2. Nasal Hygiene

   • Use saline nasal sprays or rinses to clear your nasal passages gently and reduce congestion without medication side effects.

3. Environmental Control

   • Keep your bedroom clean and dust-free, use air purifiers if possible, and minimize exposure to common allergens like dust mites or pet dander.

4. Sleep Position and Habits

   • Elevate your head with an extra pillow while sleeping to help nasal drainage and make breathing easier at night.

5. Over-the-Counter Remedies

   • Antihistamines available in India can help control allergy symptoms; consult a doctor or pharmacist before starting any medication.

6. When to Seek Medical Advice

   • If you experience persistent breathing difficulty, worsening congestion, or symptoms that do not improve, see an allergy specialist (immunologist or ENT doctor).

7. Lifestyle and Hydration

   • Stay well hydrated and maintain a balanced diet including traditional Indian foods like dals, millets, and seasonal vegetables to support your immune system.
