Phlegm and mucus can be uncomfortable, especially when they make your throat feel coated or your chest feel congested. They commonly appear when your body is responding to a cold, respiratory infection, allergies, smoke, or other irritation.
In many cases, mucus gradually clears as the underlying cause improves. The goal is not necessarily to eliminate every bit of mucus, but to make it thinner and easier to clear while supporting your recovery.
Here are several simple measures that may help.
Drink Plenty of Fluids
Staying hydrated is one of the simplest ways to support normal mucus clearance.
Water and other suitable fluids can help prevent mucus from becoming overly thick. Warm beverages may also feel soothing when your throat is irritated.
You do not need to force large quantities of water. Drink regularly according to your thirst and individual needs.
People with certain heart, kidney, or other medical conditions may have fluid restrictions, so they should follow their healthcare professional’s advice.
Try Warm Drinks
Warm water, herbal tea, or broth can be comforting when mucus is bothering your throat.
Warm liquids may help soothe irritation and make thick secretions feel easier to manage.
You can choose a drink you enjoy rather than relying on a particular “detox” beverage.
Honey can also be added to a warm drink for adults and children over 1 year old. Honey may help soothe a cough, although it does not remove the underlying cause of mucus.
Use Humidified Air
Dry air can make an irritated throat feel worse.
Using a clean cool-mist humidifier can add moisture to the surrounding air and may make breathing feel more comfortable for some people.
If you use a humidifier, clean it regularly according to the manufacturer’s instructions. Dirty humidifiers can allow microorganisms and other contaminants to grow.
A steamy shower may also temporarily make the air feel more comfortable.
Avoid placing yourself directly over very hot steam because burns can occur.
Gargle With Salt Water
If mucus is collecting in your throat, gargling with warm salt water may provide temporary relief from irritation.
A simple mixture can be made by dissolving a small amount of salt in warm water.
Gargle without swallowing the mixture.
Salt-water gargles can soothe the throat, but they do not treat infections in the lungs or physically remove mucus from the chest.
Keep Your Head Elevated While Sleeping
Mucus can feel worse at night when you are lying flat.
Raising your head slightly while sleeping may make breathing more comfortable and can reduce the sensation of drainage collecting in your throat.
A comfortable extra pillow or an appropriately designed wedge can help.
Avoid using an unsafe sleeping position, especially for infants.
Take a Warm Shower
A warm shower can be relaxing when you have congestion.
The moisture in the air may temporarily make nasal and throat secretions feel less thick, while the warmth can help you feel more comfortable.
However, you do not need extremely hot water or prolonged exposure to steam.
The benefit is mainly comfort and moisture rather than a guaranteed method of clearing mucus from the lungs.
Stay Away From Cigarette Smoke
Smoke can irritate the airways and increase coughing and mucus production.
If you smoke, reducing or stopping can be one of the most beneficial steps for your respiratory health.
You should also try to avoid secondhand smoke, vaping aerosols, and other airborne irritants when you are congested.
If you notice that mucus repeatedly returns after exposure to smoke or strong fumes, that may be an important clue about what is irritating your airways.
Try Gentle Movement
If you feel well enough, gentle walking or normal daily movement can sometimes help you feel less congested.
You do not need intense exercise while recovering from an illness.
If you have fever, significant weakness, chest pain, dizziness, or difficulty breathing, rest and seek appropriate medical advice instead of exercising through your symptoms.
Avoid Constantly Clearing Your Throat
Repeated forceful throat clearing can irritate the throat and sometimes create a cycle in which the irritation makes you want to clear it again.
Instead, try sipping water, swallowing gently, or using a warm drink when you feel mucus in your throat.
If you constantly feel mucus or something stuck in your throat for weeks, the cause may be postnasal drainage, allergies, reflux, or another condition that should be evaluated.
Consider Saline for Nasal Congestion
Sometimes the mucus you feel in your throat is actually coming from your nose or sinuses.
This is known as postnasal drainage.
A saline nasal spray or rinse can help moisturize the nasal passages and clear mucus for some people.
If you use a nasal rinse, use sterile, distilled, or appropriately boiled-and-cooled water as recommended by health authorities. Do not use ordinary untreated tap water in a nasal irrigation device.
What About Over-the-Counter Medicines?
Some people use expectorants such as guaifenesin to help loosen mucus.
Other medicines may be appropriate depending on the cause of congestion, cough, allergies, or other symptoms.
However, medications are not appropriate for everyone.
Always read the label and follow the recommended dosage. If you take prescription medicines, are pregnant, have chronic health conditions, or are treating a child, ask a pharmacist or healthcare professional before using a new medication.
Antibiotics should not be taken simply because you have mucus. Many respiratory illnesses are caused by viruses, and antibiotics do not treat viral infections.
Avoid “Mucus-Cleansing” Claims
You may see claims online about special drinks, supplements, or cleanses that supposedly remove mucus from the lungs.
Be cautious with these claims.
Your respiratory system already has natural mechanisms for moving mucus out of the airways. Healthy habits can support those processes, but there is no special drink that needs to “flush” your lungs.
Focus instead on hydration, avoiding irritants, rest, and treating the underlying cause when necessary.
Why Is Your Mucus There in the First Place?
Mucus serves an important purpose.
It helps trap particles, microorganisms, and other irritants that enter the respiratory system.
Your body can increase mucus production when your airways become irritated or inflamed.
Common causes include colds, influenza, allergies, sinus problems, asthma, smoking, and other respiratory conditions.
The treatment that works best therefore depends on why the mucus is occurring.
What Does the Color of Phlegm Mean?
People sometimes assume that yellow or green mucus automatically means they need antibiotics.
That is not necessarily true.
Mucus can change color during a respiratory infection as immune cells and other substances become mixed with the secretions. Color alone cannot reliably determine whether an infection is bacterial.
Similarly, clear mucus does not guarantee that you are completely healthy.
Other symptoms, how long they have lasted, and your overall health are more useful when determining whether medical evaluation is needed.
When to Contact a Healthcare Professional
Most short-term mucus and congestion improve as the underlying illness gets better.
However, you should consider medical advice if symptoms are severe, persistent, repeatedly returning, or getting worse instead of better.
It is particularly important to seek medical attention if you develop difficulty breathing, chest pain, coughing up blood, severe weakness, confusion, bluish or gray lips or skin, or other serious symptoms.
A persistent cough or ongoing mucus production can sometimes be related to asthma, chronic bronchitis, allergies, reflux, smoking-related airway disease, or another condition that requires evaluation.
When Chest Congestion May Be More Serious
Chest mucus accompanied by significant shortness of breath, high or persistent fever, chest pain, rapid breathing, or worsening illness should not simply be treated at home.
People who are older, pregnant, immunocompromised, or living with conditions affecting the heart or lungs may also need medical advice sooner when they develop respiratory symptoms.
If you are struggling to breathe or experiencing a medical emergency, seek urgent medical care rather than relying on home remedies.
Give Your Body Time to Recover
When mucus is caused by a common respiratory infection, recovery may take time.
Trying numerous remedies at once is usually unnecessary.
Instead, focus on the basics: rest when you need it, drink appropriate fluids, avoid smoke and other irritants, keep the air comfortably humidified, and use simple measures that make your symptoms easier to manage.
If symptoms are not improving or you are concerned about the cause, speak with a healthcare professional.
Final Thoughts
Phlegm and mucus are often signs that your respiratory system is responding to an infection or irritation.
For many people, simple measures such as staying hydrated, drinking warm fluids, using humidified air, gargling with salt water, keeping the head elevated while sleeping, and avoiding smoke can help make mucus easier to manage.
There is no need for an extreme “lung cleanse.”
The most effective approach is to support your body’s normal mucus-clearing processes while addressing the reason the mucus is being produced.
If you develop breathing difficulties, chest pain, blood in your phlegm, severe symptoms, or mucus and coughing that persist longer than expected, seek medical advice. Persistent respiratory symptoms deserve proper evaluation rather than repeated home treatment.
