Overview

The head cold, also known as the common cold, is usually a mild illness, but it can impact your daily life. In addition to sneezes, sniffles, coughs, and a sore throat, a head cold can leave you feeling tired, rundown, and generally unwell for several days.

Adults get two or three casesTrusted Source of the head cold each year. Kids can catch eight or more of these illnesses annually. Colds are the main reason why kids stay home from school and adults miss work.

Most colds are mild and last about a week. But some people, especially those with a weakened immune system, can develop more serious illnesses as a complication of a head cold, such as bronchitis, a sinus infection, or pneumonia.

Learn how to spot the symptoms of a head cold and find out how to treat your symptoms if you do come down with a cold.

What’s the difference between a head cold and a chest cold?

You might have heard the terms “head cold” and “chest cold.” All colds are basically respiratory infections caused by a virus. The difference in terms usually refers to the location of your symptoms.

A “head cold” involves symptoms in your head, like a stuffed, runny nose and watery eyes. With a “chest cold,” you’ll have chest congestion and a cough. Viral bronchitis is sometimes called a “chest cold.” Like colds, viruses also cause viral bronchitis.

Head cold symptoms

One way to know whether you’ve caught a head cold is by the symptoms. These include:

a stuffed or runny nose

sneezing

sore throat

cough

low-grade fever

general ill feeling

mild body aches or headache

Head cold symptoms usually appear one to three days after you’ve been exposed to the virus. Your symptoms should last for seven to 10 daysTrusted Source.

Head cold vs. sinus infection

A head cold and sinus infection share many of the same symptoms, including:

congestion

dripping nose

headache

cough

sore throat

Yet their causes are different. Viruses cause colds. Although viruses can cause sinus infections, often these illnesses are due to bacteria.

You get a sinus infection when bacteria or other germs grow in the air-filled spaces behind your cheeks, forehead, and nose. Additional symptoms include:

discharge from your nose, which may be a greenish color

postnasal drip, which is mucus that runs down the back of your throat

pain or tenderness in your face, especially around your eyes, nose, cheeks, and forehead

pain or ache in your teeth

reduced sense of smell

fever

fatigue

bad breath

What causes a head cold?

Colds are caused by viruses, most commonly rhinovirusesTrusted Source. Other viruses that are responsible for colds include:

human metapneumovirus

human parainfluenza virus

respiratory syncytial virus (RSV)

Bacteria don’t cause colds. That’s why antibiotics won’t work to treat a cold.

You catch a cold when someone who’s infected sneezes or coughs, and sprays droplets containing the virus into the air. Another way to get sick is by touching surfaces, like doorknobs, phones, or toys, that have the virus on them. The virus can get into your body when you touch your eyes, nose, or mouth.

You’re more likely to catch a cold if you have a weakened immune system or you smoke. Colds spread more in the fall and winter months than in the spring and summer.

When should you see a doctor?

Colds are usually mild illnesses. You shouldn’t need to see a doctor for general cold symptoms like a stuffed nose, sneezing, and coughing. Do see a doctor if you have these more serious symptoms:

trouble breathing or wheezing

a fever higher than 101.3°F (38.5°C)

a severe sore throat

a severe headache, especially with a fever

a cough that is hard to stop or that doesn’t go away

ear pain

pain around your nose, eyes, or forehead that doesn’t go away

rash

extreme fatigue

confusion

Call your doctor if your symptoms haven’t improved after seven days, or if they get worse. You could have one of these complications, which develop in a small number of people who get colds:

bronchitis

ear infection

pneumonia

sinus infection (sinusitis)

Treatment

You can’t cure a cold. Antibiotics kill bacteria, not the viruses that cause colds.

Your symptoms should improve within a few days. Until then, here are a few things you can do to make yourself more comfortable:

Take it easy. Rest as much as you can to give your body time to recover.

Drink lots of fluids, preferably water and fruit juices. Stay away from caffeinated drinks like soda and coffee. They’ll dehydrate you even more. Also avoid alcohol until you
