Clearing excess mucus or phlegm from your airways is often referred to as “draining your lungs.” Mucus buildup is a common symptom associated with various respiratory conditions and can lead to discomfort, making breathing more difficult. The primary aim of these at-home methods is to help your body naturally expel this accumulation, providing relief and supporting clearer airways.
Techniques for Mucus Clearance
Staying well-hydrated is important for maintaining healthy airways and aiding in mucus clearance. Adequate fluid intake keeps the mucus lining in your lungs at an optimal consistency, making it easier to move and expel. Dehydration thickens mucus, hindering its movement. Aim for around eight glasses of water daily, though individual needs vary.
Inhaling steam can moisten respiratory passages and loosen thick mucus, making it easier to expel. This method, known as steam therapy, involves breathing warm, moist air to soothe irritated airways and promote mucus clearance. You can do this by taking a hot shower, using a humidifier, or carefully leaning over a bowl of hot water with a towel draped over your head to trap the steam.
Controlled coughing effectively brings up mucus without excessive strain. This technique uses deep, deliberate breaths and controlled exhalations to mobilize secretions. To perform, sit comfortably, lean slightly forward, and take a slow, deep breath through your nose. Hold for two to three seconds to get air behind the mucus, then cough two to three short, sharp coughs with a slightly open mouth to expel it.
Postural drainage uses gravity to move mucus from specific lung areas into larger airways. This involves positioning your body so the mucus-filled section is elevated, allowing gravity to assist drainage. For example, lying on your stomach with pillows under your hips can drain the lower back parts of your lungs, while lying on your side with propped-up hips targets the sides. Hold each position for at least five minutes. This can be combined with gentle chest percussion, where a cupped hand rhythmically taps the chest wall to dislodge mucus.
Deep breathing exercises can expand the lungs and mobilize secretions. One technique involves sitting or standing comfortably with elbows slightly back for fuller chest expansion. Take a deep breath, hold it as long as comfortable, then exhale and follow with a strong cough to clear air passages. Repeating this several times an hour can prevent air trapping and promote better lung function.
When to Seek Medical Attention
While these home techniques offer symptomatic relief, they are not a substitute for professional medical diagnosis or treatment. Seek medical attention if your cough persists or worsens, or if you experience shortness of breath, chest pain, or a fever. Other warning signs include coughing up blood, discolored or foul-smelling mucus, or if symptoms do not improve after a few days of consistent home care. Consulting a healthcare provider is important if an underlying respiratory condition is suspected, as professional guidance ensures appropriate management.
