Common Cold Causes

Everyone knows how terrible a cold can feel. What makes the common cold so common?

 

Sneezing. Coughing. Runny nose. Year in and year out, millions of people in the U.S. come down with what is known as the common cold. (You can understand why it’s called “common.”)

In fact, adults on average get 2 to 3 colds a year, and kids get them even more often—anywhere from 6 to 8 colds per year, on average.1,2 That’s because children tend to be in close contact with other children, and their immune systems are still adapting to being exposed to the viruses that cause the common cold for the first time.

Which leads us to the causes of the common cold. There are some 200 different respiratory viruses that can cause a cold.3 The most common of these are called rhinoviruses.1 In addition to causing the common cold, rhinoviruses can also trigger asthma attacks and have even been linked to sinus and ear infections. Other, less common, culprits that can lead to a common cold include parainfluenza viruses, coronaviruses, and adenoviruses.

How Does the Common Cold Spread?

Unfortunately, the common cold is very contagious. That’s because the viruses that cause colds can spread easily from infected people to others through the air and close personal contact. The viruses can spread through tiny droplets released into the air whenever a sick person coughs, sneezes, or blows their nose near someone else.

You can also get infected by touching a surface, like a doorknob, with virus droplets on it or by sharing contaminated objects—such as utensils, towels, toys, or phones—with someone who’s sick. So if you touch your eyes, mouth, or nose right after contact or exposure, you’re likely to catch a cold.

People who are sick are most contagious for the first 2 to 3 days of a cold.3 After about a week, most people are no longer contagious.

Should I See a Doctor for the Common Cold?

Most of the time, you won’t need to see your healthcare provider when you have a cold. Colds typically go away on their own and symptom relief can be found with over-the-counter medication and home remedies. However, if your symptoms are long-lasting or severe, you should call your healthcare provider. Keep an eye out for these signs:4

  • Symptoms lasting longer than two weeks.
  • Symptoms that worsen or new symptoms. This could indicate that you have another type of infection.
  • A sore throat or fever higher than 100°F for longer than three days.
  • Intense chest pain and shortness of breath.

How Do You Treat the Common Cold?

While there is no immediate cure for the common cold, the good news is that most people recover in about 7 to 10 days.1 To learn how to get rid of a cold and help prevent colds from coming on, check out these tips so you can protect yourself and your loved ones.

  • Pain relievers. If you’re experiencing a headache or body aches while you have a cold, pain relievers like acetaminophen can ease your symptoms.

Home Remedies for the Common Cold

Although taking medication will provide the most symptom relief, there are other lifestyle choices and home remedies that can help your symptoms. If you have a cold, check out these tips for finding symptom relief at home:5

  • Stay hydrated with plenty of fluids.
  • Get a good night’s sleep and remember to rest during the day.
  • Soothe your throat by gargling with salt water or sipping warm liquids.
  • Try honey in hot water or tea to aid a cough.
  • Add moisture to the air with a humidifier to help congestion.

 

What to Avoid when You Have a Cold

When you’re not feeling well, some things can make your symptoms worse. Avoid these things when you have a cold:4

  • Antibiotics. For a cold, antibiotics are unnecessary as they are used to treat bacterial infections, not viruses. Taking unnecessary antibiotics can be harmful.
  • Alcohol. Alcohol can worsen cold symptoms and disrupt your sleep, an important part of the recovery process.
  • Smoking. Smoking can make symptoms feel worse and even prolong the length of your cold.

 

Cold Prevention

You won’t always be able to prevent catching a cold, but there are steps you can take to minimize your risk.3

  • Wash your hands, especially before eating and after coming in contact with someone who has a cold.
  • Avoiding touching your face, as cold viruses can spread from your hands to your eyes, nose, and mouth.
  • Clean frequently used surfaces such as doorknobs.

Strengthen your immune system with plenty of rest, exercise, and a healthy diet.As annoying and uncomfortable the common cold can be, this sickness is luckily not serious and symptoms can usually be soothed. Taking the steps to prevent a cold and making sure to not aggravate symptoms when you are sick will ensure you stay healthy and feel your best.
