Common cold is an acute contagious disease of the upper respiratory tract. Adults have an average of 4-6 colds per year, and children have even more.

Causes

Common cold is caused by more than 200 different viruses. Rhinovirus is the most common cause, accounting for 10 to 40 percent of colds. Coronavirus and respiratory syncytial virus (RSV) also cause this medical condition.

These viruses are made up of DNA or RNA coated in protein. They cause illnesses by latching on to a host's cell, and hijacking its processes. This makes the cell replicate the genetic material of the virus.

Symptoms

Symptoms vary depending on the virus, and on the age and general health of the patient. They generally appear 24–72 hours after infection.

Sore throat is the first symptom, followed by nasal stuffiness and runny nose, sneezing and coughing.

Cough is worse on the fourth or fifth day of the condition, while the nose symptoms improve. The nasal discharge is initially watery, and becomes thicker and yellowish. This does not necessarily indicate a bacterial infection.

Headache, fatigue, hoarseness, conjunctivitis and muscle pain (not always) are other symptoms of common cold.

Common cold is infectious from a few days before the symptoms appear until all of the symptoms are gone.

Diagnosis

Common cold is diagnosed by symptoms. If the doctor suspects bacterial infection or other illness, he or she may order chest X-ray or other tests.

Treatment

There is no cure for common cold. These viruses mutate very frequently, which makes it “easier for them to escape a drug,” said Susan Hafenstein, a structural virologist with the College of Medicine at Penn State.

The most important thing you can do is drink a lot of fluids to keep your body hydrated. This will help prevent another infection from setting in.

Gargling, an old-school remedy, eases sore throat. You can choose from a variety of saltwater gargle recipes, including gargling with one teaspoon of salt mixed in a cup of warm water.

Warm liquids have a soothing effect. They ease congestion. Lemon water with honey can loosen congestion and prevent dehydration.

Regarding nasal congestion, apply saline or warm water with salt on the nose for quick relief.

Practice yoga asanas like Uttanasana. These asanas bring energy to the head and respiratory area and heal various symptoms of this medical condition naturally.

Nasal decongestants, cough suppressants, expectorants, antihistamines and analgesics are used to treat the symptoms of this condition.

Prevention

Do yoga daily. Yoga asanas like Tadasana are immune system boosters. Wear a face mask when you go outside. Avoid large crowds.

Sleep for at least eight hours during the night. During long periods of sleep, the body releases cytokines.

Cytokines are a type of protein that regulates the immune system which in result helps the body to fight infections.

Summary

Common cold is a contagious disease.

It is caused by more than 200 viruses.

Symptoms appear 24–72 hours after infection.

It is diagnosed by symptoms.

Lemon water with honey can loosen congestion.
