Drinking a moderate amount of fluids, like water and others, can help in thinning the mucus to allow easier removal via cough. The best is to drink water, and if you want, warm liquids such as infusions or honey with lemon. 

• Hydration keeps the mucus thin, so it’s easier to remove.
• Warm liquids soothe the throat and chest, easing breathing.

1. Consume Mucus-Clearing Foods

Many foods naturally help reduce phlegm and make it easier to remove them. A few examples include:

• Ginger: Ginger’s anti-inflammatory properties help reduce mucus in the lungs. 
• Turmeric: Turmeric contains curcumin, which has anti-inflammatory and antioxidant effects. Drinking turmeric milk (haldi doodh) can soothe mucus buildup.
• Pepper: Black pepper (gol mirch) contains piperine, which helps break down mucus. 
• Garlic: Garlic acts as a natural antibiotic, helping to prevent infections that cause mucus buildup.
• Honey:  Honey’s soothing properties help thin mucus and clear the respiratory tract. 

1. Herbal Remedies

Herbal remedies can remove phlegm from the lungs. Here are a few herbal teas that may help:

• Pudina Chai: Menthol in pudina acts as a natural decongestant and breaks down mucus.
• Ajwain Chai: Ajwain’s antibacterial properties aid in thinning mucus in the airways.
• Mulethi Chai: This herbal remedy reduces inflammation.

1. Use a Humidifier

Using a humidifier keeps the air moist, helping to reduce mucus production. Dry air can irritate the lungs and create more mucus. Keeping the air moist can relieve the respiratory tract and make it easier to remove phlegm.

1. Deep Breathing Exercises

Deep breathing exercises increase lung capacity and improve oxygen flow, helping to loosen mucus.

• Sit comfortably and take a deep breath through your nose.
• Hold your breath for 2-3 seconds, then slowly exhale through your mouth.
• Repeat for 10 minutes, 2-3 times a day.

1. Physical Activity

Regular physical activity helps remove mucus from the lungs. Activities like deep breathing, controlled coughing, and specific respiratory physiotherapy exercises can mobilise mucus. Techniques such as the “screw” movement and diaphragm exercises stretch the chest & improve airflow helps in the removal of mucus.

1. Saltwater Gargle

Gargling with salt water clears mucus from the throat and lungs. It kills bacteria and relieves an irritated throat, making it easier to cough up phlegm.

• Mix half teaspoon of salt in a glass of warm water.
• Gargle for 30 seconds and spit it out.

1. Postural Drainage

Postural drainage uses gravity to help drain mucus from the lungs. Specific positions allow mucus to drain into the throat, making it easier to remove.

• Lie on your back or stomach with your hips elevated using pillows.
• Stay in this position for 10-15 minutes, allowing gravity to do its work.
• Sit up afterwards and try to cough out the loosened mucus.

Causes of Mucus Production

Excessive mucus in the lungs often points to underlying health conditions. Some common causes include:

• Infections: Illnesses like colds, flu, bronchitis, and pneumonia cause the body to increase mucus production as it fights off germs.
• Allergies: In sensitive individuals, allergens can cause inflammation and trigger excess mucus production. Like you may experience sneezing problem.
• Smoking: Tobacco smoke irritates the lungs and leads to overproduction of mucus.
• Chronic Conditions: Diseases like chronic obstructive pulmonary disease (COPD), cystic fibrosis, and bronchiectasis are linked to continuous mucus build-up.
• Gastroesophageal Reflux Disease (GERD): Acid reflux irritates the throat and causes postnasal drip, leading to mucus build-up in the lungs.
