Cold drinks

One thing to keep in mind is that you shouldn't drink cold water when you have a cough with phlegm. Cold water can thicken the mucus in your throat, making it harder to expel and worsening symptoms.

Instead, you should drink warm water, which will help soothe your cough, reduce irritation, and thin out phlegm, making it easier to expel. Additionally, cold drinks can dry out your throat, worsening your cough.

Soft drinks, carbonated drinks, caffeine

You should avoid soft drinks, carbonated drinks, and caffeinated beverages. These types of drinks often contain many artificial ingredients and added sugar, which can irritate the throat and worsen coughing.

In addition, caffeine can cause dehydration, which is even worse when the body is already dehydrated during the mucus production process.

Alcoholic beverages

The alcohol in wine and beer can interfere with the normal functioning of the immune system, weakening its ability to fight off disease-causing bacteria and viruses.

This not only prolongs a productive cough but can also worsen the condition. To recover quickly, you should limit or avoid alcoholic beverages while you have a productive cough.

Spicy drinks

Capsaicin, the compound that creates the spicy flavor in spicy foods, can worsen coughing, irritating the throat and making the cough more intense and prolonged.

Capsaicin, the compound that creates the spicy flavor in spicy foods, can worsen coughing, irritating the throat and making the cough more intense and prolonged.

Instead of consuming spicy or hot drinks, opt for milder options, such as warm vegetable broth, to soothe the throat and reduce irritation. People with a phlegmatic cough should avoid spicy foods and hot drinks, as these can slow down recovery.

Note for people with a productive cough (cough with phlegm):

When experiencing a productive cough (with phlegm), proper care is crucial to thin and facilitate its expulsion. Some suggestions to help reduce symptoms and improve overall health include:

Adopt a healthy diet: Eating fresh, natural, and nutritious foods will support the immune system and help the body recover quickly.

A diet rich in fiber, vitamins, and minerals is essential for improving the health of people with phlegmatic coughs.

Drink plenty of water: When you have a cough with phlegm, drinking plain water is the ideal choice.

Everyone, especially those with a productive cough, should drink at least 2 liters of water daily to help detoxify the body and keep cells hydrated, thus making it easier to thin the phlegm.

Moderate exercise: While rest is necessary when you're sick, moderate exercise is also very important.

Physical activity not only helps boost the immune system but also improves overall health and reduces the severity of respiratory illnesses such as coughs with phlegm.

Use a humidifier: To help thin the phlegm, a humidifier can be used in the home. Humid air can help patients cough up phlegm more easily, reducing discomfort in the throat.

Saltwater gargling: Gargling with warm saltwater (add about 1/2 teaspoon of salt to a cup of warm water) can help thin mucus and effectively clear the respiratory tract.

Using expectorants: Another treatment method is to use expectorants as directed by a doctor or pharmacist. These medications help to thin mucus, making it easier for the patient to cough up phlegm.

Using eucalyptus oil: Products containing eucalyptus oil can help thin mucus in the chest, reducing feelings of congestion. Patients can refer to and use these products according to the instructions on the label or as advised by their doctor.
