Cough: Causes, Types of Coughs, and What Can Help

Coughing is a natural protective reflex. It helps the body remove mucus, dust, pathogens, and other foreign substances from the respiratory tract.

When you have a cold, the cough often starts out dry and irritating. As the cold progresses, mucus may build up, which is then cleared from the airways by coughing. The appropriate measures to take therefore depend on the type and cause of the cough.

What is a cough?

The airways are lined with a mucous membrane and tiny cilia. These help transport inhaled particles and mucus toward the throat.

When sensitive cough receptors are stimulated, the body triggers a forceful burst of air. This is intended to clear the airways of irritants as quickly as possible.

A cough is therefore not a disease in and of itself, but rather a symptom that can have various causes.

Dry cough

With a dry cough, little or no phlegm is coughed up. It often feels scratchy, painful, or irritating, which is why it is also called a dry cough. A dry cough often occurs at the beginning or toward the end of a cold. It can be particularly bothersome at night and disrupt sleep.

Productive Cough

A productive cough causes mucus to build up in the airways. The cough reflex helps transport this mucus upward so it can be coughed up. A productive cough should not be suppressed without professional advice, as the mucus needs to be cleared from the airways.

Common Causes of Coughs

A cold is a common cause of acute cough. However, a cough can also be triggered by other medical conditions or irritants.

Possible causes include:

  • Colds and Other Respiratory Infections
  • irritated or dry mucous membranes
  • Bronchitis
  • Allergies
  • Asthma
  • Smoking
  • Dust and other irritants
  • cold or dry air
  • Heartburn and Acid Reflux
  • certain medications
  • chronic respiratory diseases

A cough without any apparent cold, a recurring cough, or symptoms that persist for a long time should be evaluated by a doctor.

Cough with a Cold

With a cold, the cough may change over time:

  1. At first, the mucous membranes become irritated. This often leads to a dry, dry cough.
  2. After a few days, mucus may start to build up.
  3. The cough becomes productive and helps clear out the mucus.
  4. Toward the end of a cold, a dry, tickling cough may return.

Even after the other cold symptoms have subsided, the cough may persist for some time.

What helps with a cough?

Simple measures can help soothe irritated airways and make it easier to cough up phlegm.

Drink enough fluids

Water and unsweetened teas help keep your mouth and throat moist. If you have a cough with thick mucus, drinking enough fluids can help keep the mucus from becoming too thick.

Keep the indoor air comfortable

Dry and overheated rooms can make a cough worse. Regular ventilation and a comfortable room temperature are good for the respiratory tract.

Avoid smoke and irritants

Tobacco smoke, dust, strong odors, and cold air can further irritate the respiratory tract. During a cold, such irritants should be avoided as much as possible.

Rest and Sleep

A respiratory infection takes a toll on the body. Getting enough sleep and temporarily reducing your workload can help you recover.

Raise your upper body slightly

If you cough mainly at night, you can prop up your upper body slightly by using an extra pillow.

Coughing Gently

Very severe and uncontrolled coughing can put additional strain on the already irritated airways. Therefore, it may be helpful to cough as controlled as possible.

For a dry cough:

  • breathe in through your nose
  • Sit as upright as possible
  • Cough gently into your closed fist or a handkerchief
  • puff out your cheeks slightly
  • Keep breathing calmly between coughing fits

When coughing up phlegm, you should try to bring the phlegm up with as few, targeted coughs as possible.

Home Remedies for a Cough

Hot Beverages

Lukewarm tea or water can help moisturize the throat and may feel soothing. Very hot beverages should be avoided, as they can further irritate the mucous membranes.

Honey

Honey can be soothing for a cold-related cough and a sore throat. It can be taken straight or mixed into a lukewarm drink.

Children under one year of age should not be given honey.

Inhalation

Inhaling saline solution can help moisturize the airways. The water should not be too hot to avoid scalding. Safe use is especially important for children.

Chest and Neck Compresses

Warm compresses can be soothing. They should be at a comfortable temperature and should not be used if you have a fever or are feeling significantly unwell.

Medicinal Plants for Coughs

Depending on whether the cough is dry or productive, different herbs may be appropriate.

How long does a cough last?

An acute cough usually lasts up to three weeks. However, after a respiratory infection, the cough may persist even after the other symptoms have subsided.

Depending on the duration, a distinction is made between:

  • acute cough: up to three weeks
  • subacute cough: three to eight weeks
  • Chronic cough: longer than eight weeks

A persistent cough should be evaluated by a doctor. This applies even if there are no other symptoms.

When should you see a doctor if you have a cough?

A medical evaluation is recommended in the following cases:

  • A cough that lasts for several weeks
  • Shortness of breath or increased difficulty breathing
  • Chest pain or tightness
  • high or prolonged fever
  • bloody sputum
  • sputum that is thick or unusually colored
  • persistent hoarseness
  • severe exhaustion
  • unintentional weight loss
  • a persistent cough
