What is the Common Cold?
The common cold is a viral infection of your nose and throat (upper respiratory tract). It is usually harmless, although it may not feel that way. Many different viruses can cause a common cold, with rhinoviruses being the most common.
Most adults get 2 to 3 colds per year. A cold usually lasts 7 to 10 days, though some symptoms may linger for up to 2 weeks.
Common Symptoms
Early Symptoms (Day 1-3)
- Scratchy or sore throat
- Runny nose (clear, watery)

Later Symptoms (Day 3-7)
- Nasal congestion (blocked nose)
- Thicker nasal discharge (yellow/green)
- Cough (dry or with mucus)

How to Manage a Cold at Home
Home Care Tips
- Rest: Give your body time to fight the infection. Avoid overexerting yourself.
- Stay hydrated: Drink plenty of water, warm soups, herbal teas, and warm water with honey and lime. Avoid cold drinks.
- Steam inhalation: Breathe in steam from hot water (with or without a few drops of eucalyptus oil) to relieve congestion. Be careful not to burn yourself.
- Gargle with warm salt water: Mix half a teaspoon of salt in a glass of warm water and gargle to soothe a sore throat.
- Use saline nasal drops: To relieve nasal congestion naturally.
- Elevate your head: Use an extra pillow when sleeping to help with nasal drainage.
- Honey: A spoonful of honey can soothe a cough (for adults only, not for children under 1 year).
Over-the-Counter Medications
- Paracetamol (Panadol): For fever, headache, and body aches. Take as directed on the package.
- Antihistamines: (e.g., Chlorpheniramine/Piriton) for runny nose and sneezing. May cause drowsiness.
- Decongestants: (e.g., Pseudoephedrine) for nasal congestion. Avoid if you have high blood pressure.
- Cough lozenges: For sore throat relief.
Note: Antibiotics do NOT work against colds. Colds are caused by viruses, not bacteria. Do not take antibiotics unless prescribed by a doctor for a secondary bacterial infection.
