What You'll Learn

Dairy products like milk and cheese can worsen congestion
Dairy products like milk, cheese, butter, yoghurt, and ice cream may worsen congestion due to their mucus-producing nature. While some mucus is necessary for the body to get rid of harmful microbes, an excess can be detrimental. For instance, people with asthma produce too much mucus in the lungs, which can be dangerous.
The Lung Institute recommends that patients with COPD who produce excess mucus in the lungs avoid dairy products. Furthermore, a 2018 study in the Laryngoscope found that patients who complained of having too much mucus experienced worsening symptoms after consuming dairy. Conversely, subjects on dairy-free diets saw a significant reduction in symptoms.
However, the connection between milk and mucus production is disputed. One study published in the American Review of Respiratory Diseases found no difference in the amount of nasal mucus produced in people with colds who drank milk versus those who did not. Another study in the Journal of the American College of Nutrition reported similar findings, concluding that milk consumption did not increase mucus production or worsen symptoms in people with asthma.
Despite the mixed scientific data, many people who experience colds or sore throats insist that dairy products exacerbate their symptoms. If you have lactose intolerance, avoiding dairy during a cold or sore throat is advised, as it may increase congestion.

Caffeine and alcohol can increase mucus production
While cheese is often thought to increase mucus production, scientific data on this is mixed. However, it is clear that caffeine and alcohol can increase mucus production.
Caffeine is known to stimulate gastric acid secretion, but its effects on gastric mucus secretion are unclear. Some studies indicate that caffeine does not increase mucus secretion and, in fact, inhibits it. However, the Lung Health Institute reports that caffeine can cause some bodies to produce more thick mucus. Therefore, those concerned about mucus production should avoid energy drinks, coffee, and black tea.
Alcohol consumption can also cause excessive mucus production. This is due to its dehydrating effect on the body, which increases the thickness of airway mucus. Alcohol also irritates the respiratory tract lining, leading to inflammation. Furthermore, alcohol weakens the immune system and damages the cough reflex, making the body more susceptible to respiratory illnesses. Certain alcoholic beverages also contain histamines and sulfites, which can trigger asthma and allergies.
The impact of alcohol on mucus production and airway function has not been extensively studied. However, some research suggests that brief exposure to modest amounts of alcohol may improve airway clearance, while prolonged exposure to high concentrations of alcohol impairs airway clearance and ciliary motility.
Overall, while cheese may or may not increase mucus production, caffeine and alcohol consumption can certainly contribute to excess mucus.

Lactose intolerance and dairy consumption
Dairy products are often the first foods that come to mind when thinking about what to avoid with chest congestion. While some people believe that milk, cheese, and ice cream increase mucus production, the scientific data is mixed. For instance, a study in the Laryngoscope found that patients who complained of having too much mucus experienced worsening symptoms after consuming dairy. On the other hand, a study in the Journal of the American College of Nutrition found that milk consumption did not increase mucus production or worsen symptoms in people with asthma.
If you have lactose intolerance, consuming milk or other dairy products during a cold or chest congestion may lead to increased congestion. Lactose intolerance is the inability to digest lactose, a sugar found in milk and dairy products. This occurs when the small intestine does not produce enough lactase, an enzyme needed to break down and absorb lactose. Symptoms of lactose intolerance include diarrhea, gas, bloating, stomach pain, and nausea, and they typically begin within a few hours of consuming lactose.
Most people with lactose intolerance can manage the condition without completely eliminating dairy from their diet. The severity of symptoms depends on various factors, such as the amount of lactose consumed and individual sensitivity. Lactose intolerance can be managed through diet changes, and some people may tolerate certain dairy foods in small amounts or when combined with other foods. Lactose-intolerant individuals can also try lactase supplements, which help the body break down lactose.
Dairy products like milk and yogurt may help ease cold and congestion symptoms by soothing sore throats. Warm milk or milk with turmeric (known for its anti-inflammatory properties) can be especially effective. Additionally, dairy provides essential nutrients like calcium, protein, and vitamin D. If you suspect lactose intolerance, it is important to consult a healthcare provider to determine which dairy foods and amounts are suitable for your condition.

Home remedies to reduce chest congestion
While cheese is not directly labelled as a congestion-causing food, dairy products are often thought to stimulate mucus production and make congestion worse. However, the scientific data is mixed, with some studies supporting this claim and others refuting it. The Lung Institute recommends that patients with COPD who produce excess mucus avoid dairy products, while other researchers report that the connection between milk and mucus production is primarily a myth.
If you are experiencing chest congestion, there are several home remedies that may help:
- Drinking liquids, especially warm liquids, can help thin out mucus and clear it out of your chest and nose.
- Using a humidifier or leaning over a bowl of hot water with a towel over your head can help ease congestion by loosening mucus.
- Drinking hot herbal tea, especially ginger, peppermint, chamomile, or thyme tea, can soothe your throat, thin mucus, keep you hydrated, and provide comfort.
- Honey has anti-inflammatory properties and can help relieve nighttime coughs in children.
- Gargling with salt water or using essential oils may help relieve congestion.
- Taking over-the-counter decongestants or expectorants can help thin mucus and make it easier to cough up.
- Getting rest, breathing in cool air, and taking deep breaths can help manage symptoms.

Upper respiratory tract infections and congestion
Upper respiratory tract infections (URTIs) are infections that affect the upper respiratory tract, which includes the nose, throat, and sinuses. Symptoms of URTIs can include sneezing, nasal congestion, a runny nose, itchy eyes, and a sore throat. More serious URTIs can result in bronchitis, sinusitis, or even pneumonia.
Congestion is a common symptom of URTIs, and it is caused by inflammation of the nasal passages, which leads to increased mucus production. While mucus is a natural substance that helps the body get rid of harmful microbes, too much of it can cause discomfort and make it difficult to breathe.
There are several things you can do to reduce congestion associated with URTIs:
- Drink plenty of fluids, especially water, to stay hydrated.
- Inhale steam or use a hot compress on the chest and throat to help loosen mucus and improve breathing.
- Avoid caffeine, as it can lead to the production of thick mucus.
- Limit alcohol consumption, as it can cause the membranes within the nose to swell, making breathing more difficult.
- Avoid smoking and exposure to secondhand smoke, as this is a common cause of URTIs and can worsen congestion.
In terms of diet, some people believe that dairy products, such as milk, cheese, and ice cream, should be avoided when dealing with congestion. This is because dairy is thought to stimulate the production of mucus and worsen congestion. However, the scientific data is mixed, and some studies have found no link between dairy consumption and increased mucus production. It is important to note that dairy products can be helpful for sore throats, as they are soft and easy to swallow, and they provide nutrients like vitamin D and calcium.
Overall, while cheese may not need to be strictly avoided during an URTI, it is important to follow general guidelines for managing congestion and seek medical advice if symptoms persist or worsen.
