Causes and Symptoms of the Common Cold and How to Treat It at Home

We all experience the common cold, especially during winter, when numerous viruses affecting the respiratory system are widespread. Drinking a warm beverage can help soothe cold symptoms, while some individuals may need medication.

In the following lines, we present ways to treat the cold and flu, as well as explore its symptoms, causes, and how you can prevent it.

What’s the difference between a cold and the flu?

A cold is a contagious viral illness that affects the upper respiratory tract.

Its symptoms vary from person to person, as do the viruses that cause it. These viruses spread easily through droplets from an infected individual.

Drinking warm fluids and getting enough rest is the best approach to treatment, in addition to effective home remedies.

How long does a cold last?

The incubation period of the virus in the body is about 12 to 72 hours, after which symptoms begin to appear. The illness typically lasts around 7 to 10 days.

A person can be contagious from the moment the virus enters the body until full recovery, with the most contagious period being when symptoms appear.

What are Cold Symptoms?

Cold symptoms appear as your immune system responds to the virus. Colds progress through three stages, with symptoms varying across each phase:

1. Early Stage

Occurs within 1–3 days of the virus entering the respiratory tract and includes:

1. Sneezing
2. Sore throat
3. Cough
4. Nasal congestion and blockage
5. Hoarseness

2. Active Stage

As the immune response intensifies (days 4–7), symptoms worsen and may include:

1. Headache
2. Runny nose
3. Loss of appetite
4. Red eyes
5. Fatigue and general weakness
6. Chills
7. Muscle aches

3. Final Stage

Most symptoms begin to fade, and the patient partially recovers. However, coughing may persist for several days in some individuals.

What are Cold Symptoms in Children?

Children have weaker immune systems than adults, which can worsen their symptoms:

1. High fever
2. Cough
3. Sneezing
4. Runny nose (initially clear, then gray or yellow and thicker over time)
5. Sore throat and swollen glands
6. Drooling
7. Difficulty swallowing
8. Loss of appetite

What Causes the Common Cold?

More than 200 types of viruses can cause the common cold, with rhinoviruses being the most common.

COVID-19 (Coronavirus) has also been a major cause of cold-like symptoms in recent years.

The virus inflames the lining of the nose and throat, resulting in symptoms ranging from mild and treatable at home to severe complications that may require hospitalization.

What are Causes of Colds in Children?

Children catch colds more frequently than adults due to their underdeveloped immune systems.

A child may catch a cold 6–10 times per year, compared to 2–4 times for adults.

High infection rates in winter aren’t due to the season itself, but rather:

1. Crowding in schools or daycare
2. Dry air making airways more vulnerable
3. More indoor interaction, allowing easier spread among family members

Is the Cold Contagious?

Absolutely yes. The common cold is one of the most contagious illnesses and can spread through:

1. Infected droplets from sneezing
2. Touching the eyes or nose after contact with contaminated surfaces

What’s the Difference Between a Cold and the Flu?

Many people confuse the two, but colds and the flu are not the same.

The flu is caused by influenza viruses, which frequently mutate and tend to cause more severe symptoms than the common cold.

The body develops immunity to influenza after infection, so symptoms tend to be less severe upon reinfection.

Flu vaccines are available to enhance resistance, but no specific vaccine exists for the common cold.

Flu complications can be severe, such as pneumonia, and may even lead to death.

Flu symptoms include:

1. High fever
2. Severe cough
3. Headache
4. Intense body pain and fatigue
5. Unlike colds, sore throat and sneezing are not prominent, and nasal congestion is less common.

How is the Cold Diagnosed?

Some symptoms may indicate a more serious condition, and a doctor should be consulted if the following appear in children or adults:

1. Difficulty breathing
2. Ear pain
3. Persistent fever, or in infants under 2 months
4. Wheezing
5. Sleepiness
6. Irritability
7. Chest pain
8. Refusing food or drink (risk of dehydration)
9. Vomiting or abdominal pain

Doctors usually diagnose colds based on symptoms, without needing further tests.

However, if COVID-19 is suspected, imaging tests like chest X-rays may be required to diagnose pneumonia or bronchitis.

What’s the Best Treatment for a Cold?

While you can’t shorten the duration of a cold, home remedies help relieve symptoms and speed recovery:

Home Care Tips:

1. Drink plenty of warm fluids to keep the mouth and nose moist
2. Gargle with saltwater to ease sore throat
3. Get sufficient rest in bed
4. Inhale warm steam to relieve nasal congestion
5. Use saline solution to keep nasal passages moist
6. Apply petroleum jelly around the nose and lips to soothe cracked skin
7. Use lemon (rich in vitamin C) to ease symptoms
8. Take honey (for adults and children over 1 year), added to warm drinks
9. Consume warm broth for nutrition and to help open nasal passages
10. Add ginger slices or puree to food and drinks for anti-inflammatory effects
11. Eat probiotic-rich yogurt to boost immunity
12. Use a humidifier to ease nasal congestion

What are the Medications for Colds in Adults?

Choosing the right medication depends on your symptoms. Common options include:

1. Anti-inflammatories and painkillers for headaches and fever
2. Lozenges for sore throat
3. Antihistamines for runny nose and sneezing
4. Supplements with Vitamin C or zinc to support immunity
5. Cough syrups

Important: Avoid taking multiple medications with the same active ingredients to prevent overdose.

What are Cold Medications for Children?

Home remedies are generally the safest treatment for infants and children.

Medication should only be used after consulting a doctor.

Important considerations:

1. Do not give aspirin to children (risk of Reye’s syndrome)
2. Avoid ibuprofen for infants under 6 months or if vomiting is present
3. Do not give acetaminophen to children under 3 months without doctor’s advice
4. Avoid decongestant nasal drops in children under 6 years—use saline drops instead
5. Consult a doctor for appropriate cough medications and dosages

Young children cannot blow their noses effectively. Use a nasal suction device:

1. Inject warm saline into one nostril
2. Insert the suction tip (6–12 mm) to extract mucus
3. Repeat on the other side

How Can You Prevent Catching a Cold?

Since colds are contagious, preventive steps can help:

1. Wash hands regularly and use sanitizer, especially around sick people
2. Disinfect surfaces
3. Avoid touching your face while outside
4. Avoid crowded, enclosed spaces and close contact with others
5. Eat nutritious, immune-boosting foods
6. Exercise regularly
7. Clean and disinfect children's toys and personal items frequently

Final Thoughts

You may not be able to shorten the duration of a cold, but by following proper health practices and home treatments, your symptoms can improve much faster.

Make sure to follow your doctor's advice and drink plenty of warm fluids for a quick recovery.
