When it comes to colds, there is a lot of information out there about how you get them and how to treat them—and not all of it is correct. Perhaps it's because the symptoms can be so miserable, from a sore throat to postnasal drip.

Coping With The Common Cold 

There's no cure for the common cold, but certain things do help ease the symptoms. Here's a rundown of what does and doesn't work for avoiding and treating colds.

How do you catch a cold?

There are more than 200 viruses that can cause a cold. These viruses spread from person to person via viral particles in the air and close personal contact or by touching a contaminated surface.

Cut your risk of catching a cold by washing your hands frequently, not touching your face and avoiding sick people. Exercising and eating healthy foods also help.

Contrary to popular belief, getting wet and chilled can't give you a cold.

What works

Even though you have to wait for a cold to run its course, you may be able to ease symptoms with the following:

• Resting.

• Drinking plenty of fluids.

• Using a clean humidifier or cool mist vaporizer.

• Rinsing the nose with saline nasal spray or drops.

• Taking a steamy bath.

• Swallowing some honey for cough relief. (Don't give honey to a child younger than 1 year old.)

• Using an over-the-counter medicine or inhaler, as recommended by your doctor or pharmacist.

• Using oral zinc products.

What doesn't work

It's important to know that antibiotics are not effective for treating the common cold. They are only effective at treating illnesses caused by bacteria, not viruses. And their overuse can cause adverse symptoms.

Likewise, many alternative products and supplements, such as echinacea, have not been proven to be effective at treating the common cold.

When should you see a doctor?

Cold symptoms can last from two days to two weeks. Seek medical attention for any severe symptoms or serious complications, including the following:

• Difficulty breathing, fast breathing, or wheezing.

• Dehydration.

• Fever above 102 degrees or fever for longer than a few days.

• Chest pain or pressure.

• Ear pain.

• Sinus headache.

• Symptoms that last more than 10 days without improving.

• Symptoms that worsen or improve but then return or worsen.
