cough self care basics

Overview

A cough is your body's way of clearing your airways. It is a reflex that helps protect your lungs and throat from mucus, germs, or irritants like smoke. Most coughs are short-lived and are not a sign of anything serious.

Yes, a cough is one of the most common reasons people visit a doctor or stay home from work or school.

A cough can affect anyone at any age. It is especially common in children, people with asthma or allergies, and those who smoke.

Symptoms

Common symptoms

• Dry, tickly cough without mucus
• Wet cough that brings up mucus or phlegm
• Cough that is worse at night
• Cough after a cold or flu
• Sore throat or hoarse voice

Symptoms in children

• Barking cough (often from croup)
• Cough with a runny nose or fever
• Cough that gets worse when lying down
• Cough with fast breathing or a wheeze

Symptoms in older adults

Causes

Main causes

• Viral infections like the common cold or flu
• Smoking or breathing in secondhand smoke
• Allergies to pollen, dust, or pet dander
• Asthma, which can cause a dry, nighttime cough
• Acid reflux (GERD) that irritates the throat

Risk factors

• Smoking or living with someone who smokes
• Having a weakened immune system
• Being around polluted air or strong fumes
• Having a chronic condition like asthma or COPD
• Being a young child or an older adult

When to see a doctor

See a doctor urgently if:

• You have trouble breathing or feel short of breath
• You cough up blood or bloody mucus
• You have a fever that lasts more than a few days
• Your cough lasts longer than 3 weeks
• You feel very weak, dizzy, or confused

Book a routine appointment if:

• Your cough keeps you up at night or interferes with daily life
• You have a cough that is getting worse instead of better
• You have other symptoms like weight loss, chest pain, or wheezing
• You have a chronic condition like asthma or heart disease

Diagnosis

Your doctor will ask about your symptoms, when the cough started, and if you have other health conditions. They will also listen to your chest and may check your nose and throat.

Tests that may be done

• Listening to your lungs with a stethoscope
• Measuring oxygen levels with a small sensor on your finger
• A chest X-ray if the doctor needs to look at your lungs
• A sample of mucus for testing if a bacterial infection is suspected

What to expect at your appointment

A doctor visit for a cough is usually quick. Most people do not need tests. You may be asked to cough or take a deep breath so the doctor can hear how your lungs sound.

Treatment

Treatment for a cough depends on the cause. For most viral coughs, the best approach is self-care and time. If an underlying condition is found, your doctor will treat that condition.

Self-care at home

• Rest to help your body recover
• Drink plenty of warm fluids like water, broth, or herbal tea
• Use a teaspoon of honey (for adults and children over 1 year old)
• Gargle with warm salt water to soothe a sore throat
• Avoid smoke, strong scents, and cold, dry air
• Use a cool-mist humidifier in your room to add moisture to the air

Medical treatments

If a bacterial infection is the cause, a doctor may prescribe antibiotics. For asthma or allergies, you may be given inhalers or antihistamines to help open your airways or reduce irritation. Over-the-counter cough syrups are not usually recommended, especially for children, and should only be used on a doctor's advice.

When is surgery considered?

Surgery is almost never needed for a cough. It may be considered only if a serious underlying condition, such as a growth in the lungs, is discovered through further testing.

Living with this condition

A cough can be tiring and frustrating, but most people manage it at home with rest and self-care. Try to listen to your body and take it easy until you feel better.

Lifestyle tips

• Drink fluids throughout the day to keep your throat moist
• Avoid smoking and secondhand smoke
• Use pillows to prop yourself up slightly at night to ease coughing
• Wash your hands often to avoid spreading germs
• Cover your mouth with a tissue or your elbow when coughing

Diet and exercise

Eat a balanced diet with fruits and vegetables to support your immune system. Gentle activity like walking is fine if you feel up to it, but avoid any intense exercise while you are coughing heavily or feeling unwell.

Mental health and emotional wellbeing

A long-lasting cough can affect your sleep, energy, and mood. It is common to feel anxious or frustrated. If you are struggling, talk to your doctor or a trusted friend. Remember that taking care of your mental health is part of recovery.

Prevention

Not all coughs can be prevented, but you can lower your risk by staying healthy and avoiding irritants that trigger coughing.

Vaccines

Getting vaccinated against flu and other respiratory infections, as recommended by your local health authority, can help prevent some causes of cough.

Screening programmes

There is no routine screening for a cough, but if you have a chronic condition like asthma, regular check-ups can help you stay well.

Complications

If left untreated

• A bacterial infection could sometimes spread and lead to pneumonia or bronchitis.
• A cough that lasts a long time might be a sign of an underlying condition, like asthma or acid reflux, which is best to manage early.
• Severe or prolonged coughing can cause chest pain, vomiting, or even fractured ribs in rare cases.

Long-term outlook

The outlook for a cough is very good. Most coughs resolve on their own within a few weeks, and even lingering coughs often improve once the cause is found and treated. With the right support, you can feel better soon.
