Yes, you can safely swallow mucus (phlegm) from your lungs; your stomach acids break it down without harm, but spitting it out can be better if it's thick or colored, as it helps clear infection and offers diagnostic clues, though it's not required for recovery. Swallowing is a normal bodily process, but coughing it up and disposing of it is fine, especially if it feels uncomfortable or you want to help your body expel germs.
Mucus is a substance that lines the moist surfaces of your body, like your lungs and sinuses, and helps your body fight illness. Experts say it's better to spit out excess mucus when you're sick, but there's no harm in swallowing it.
Whether you spit or swallow phlegm, both are safe. Spitting can help some people feel better, especially if their cough is associated with thick phlegm that's causing distress.
If your child is one year old or older, give them warm apple juice, milk or decaffeinated tea with honey in it. The warm liquid can soothe their throat and loosen the mucus. Help clear their chests with a cool mist humidifier or steamy shower.
Hold your breath for 3 to 5 seconds. Then—as you let that breath out [coughing]— cough 2 or 3 times. Push on your belly with your arms as you cough. [coughing] Breathe in slowly and gently through your nose, and repeat the coughing if you need to.
Sometimes thick or discolored mucus clears up on its own, especially if it's caused by a mild infection or allergies. But phlegm that persists, worsens, or is accompanied by other symptoms may need medical attention.
So essentially, yellow mucus just means your immune system has been activated. For signs your cold is getting better, look for: The mucus turning clear again. Your symptoms becoming less severe, like having fever body aches and less nasal congestion.
Kids with bacterial pneumonia usually get sick quickly and have a high fever, cough, rapid breathing and maybe even chest pain with breathing. Viral pneumonia symptoms tend to appear more slowly and may be less severe, though you can see fever and cough from viruses too. Wheezing is more common in viral pneumonia.
Viral coughs most often last for 2 to 3 weeks. Sometimes, your child will cough up lots of phlegm (mucus). The mucus can normally be gray, yellow or green. Antibiotics are not helpful.
“And if you're normal and healthy, you never feel it and you just swallow it.” The mucus, together with the bacteria and other trapped substances, then goes to the stomach and eventually pass out of the body. Your body makes a lot of mucus, although no one's quite sure how much. Mucus is mostly water.
Some signs that you may need to go to urgent care with your cough include:
In some cases, the phlegm can become so thick that coughing alone is insufficient to clear it. If the phlegm is not expelled, it can obstruct the airway, leading to choking.
But it is also safe to swallow because the mucus is broken down in the stomach and is digested. It is not harmful to your health if you swallow it, but spitting it out can be of diagnostic value.
White or cloudy: While white is typically normal, cloudy mucus may be normal or indicate inflammation. Red or pink (blood-tinged): If it's from the nose, it could be irritation from frequent nose blowing or picking, but could also indicate other sources of bleeding.

Walking pneumonia is a less serious form of the lung infection pneumonia. It's often caused by bacteria called Mycoplasma pneumoniae, but other bacteria or viruses can also cause it. Most kids with this type of pneumonia (nuh-MOH-nyuh) don't feel sick enough to stay home — hence, the name "walking" pneumonia.
Early signs of pneumonia often mimic cold or flu but worsen, including fever, chills, cough (with or without mucus), fatigue, and shortness of breath, sometimes with chest pain, rapid breathing, headache, and loss of appetite, notes Healthdirect, Better Health Channel, American Lung Association, and Mayo Clinic. In older adults, confusion or disorientation can be a key sign, while infants might show restlessness or feeding difficulties, say Healthdirect, Mayo Clinic, and WebMD.
Viral pneumonia is often mild and goes away on its own within a few weeks. But sometimes it is serious enough that you need to get treatment in a hospital. If you have viral pneumonia, you are at risk of also getting bacterial pneumonia.
The most common symptoms of bronchitis are:
3 Stages of Whooping Cough
People who become infected with RSV show symptoms within four to six days after the virus enter the body. Initial signs of RSV are similar to mild cold symptoms, including sneezing, runny nose, fever, cough and decrease in appetite. Very young infants may be irritable, fatigued and have breathing difficulties.
However, having yellow or green phlegm does not mean you are having a bacterial infection and therefore require antibiotics. “But what's wrong with taking antibiotics, doctor? I get better after taking them.”
“You'll likely need a chest x-ray or CT scan to determine the cause and rule out anything sinister." Phlegm from pneumonia can be a dark brown or a vibrant yellow or green, and “it just looks gross,” Dr. Lindsay says.
Common symptoms include: Prolonged fever Breathing faster than usual Using extra effort when breathing Being too breathless to feed (young children) or complete sentences (older children) Chest pain when breathing or coughing Symptoms of a chest infection can come on over 24-48 hours or more slowly over several days.
