What might cause a chest cold?  

A chest cold, also known as acute bronchitis, happens when the airways in the lungs get swollen and produce a thick, sticky mucus. This is not the same as the common cold that can affect the upper respiratory tract.

Chest colds are usually caused by a viral infection and can get better on their own, without antibiotics. However, in some cases, chest colds can be caused by bacteria. In cases of bacterial infection, antibiotics are not recommended and they may not help someone feel better.

Possible chest cold symptoms

A symptom of a chest cold is an unpleasant cough. The cough may occur with or without mucus. Other possible chest cold symptoms include:

• Congestion
• Fatigue
• Mild body aches
• Sore throat

Since cold symptoms can be similar to signs of other respiratory illnesses, a person may consider taking an at-home test for COVID-19 or visiting a health care provider for testing if they are experiencing symptoms. 

How long can a chest cold last?

Symptoms of a chest cold may last less than three weeks. If symptoms last longer than that or if a person has difficulty breathing or shortness of breath, they should contact a health care provider for medical care. 

At-home relief options that may help support chest cold symptom relief

Many chest colds may get better on their own without antibiotics. But there are several things a person can do to help themselves feel better as the cold is running its course. At-home cold remedies and over-the-counter (OTC) medications may help support symptom relief, but they won’t cure an illness. Here are a few things a person can try to help relieve chest congestion at home.

• Getting enough rest and hydration. It’s important to stay home and rest to allow the illness to run its course. Drinking plenty of fluids is also recommended.
• Humidity. Humidifiers can help loosen mucus so people can cough it up. A product like the Vicks sinus steam inhaler may also be helpful for some people. Other ways to support symptom relief include breathing in steam from a bowl of hot water or taking a steamy shower. 

Over-the-counter (OTC) products that may help support symptom relief

To help feel better with bronchitis, someone may consider these OTC options after speaking with a health care provider:

• Cough suppressants. There are a few ways that cough medicine can help ease this symptom. A cough suppressant such as dextromethorphan doesn’t treat the cause of the cough, but instead it decreases activity in the part of the brain that causes the coughing reflex. But children younger than 4 years old shouldn’t use OTC cold medications unless prescribed by a health care provider.
  
  Some options adults can try include Delsym cough suppressant liquid or CVS Health 12-hour cough DM cough suppressant. Only give children cough medication specifically labeled for kids their age.

• Lozenges. Cough drops and lozenges can be comforting to adults suffering from a sore throat. 
  
  Options for grownups include CVS Health cherry cough drops, CVS Health honey lemon cough drops and Ricola Max throat care cough drops.

• Pain relievers and fever reducers. Some pain relief products can help to temporarily reduce fever and support temporary relief of aches and pains. For children, speak with a health care provider on which medications to give.
  
  Some OTC pain relievers include CVS Health extra-strength acetaminophen pain reliever and fever reducer, Tylenol 8-hour muscle aches and pain tablets with acetaminophen, CVS Health ibuprofen pain reliever and fever reducer and Advil pain reliever and fever reducer.

Helping to prevent chest colds

Colds are most often spread from person to person through droplets of fluid from an infected person, from sneezing or coughing, or by touching a contaminated surface. Coughs are powerful reflexes which help protect the airway from germs and dust. In addition to bringing up mucus and phlegm, they can propel particles out of the lungs at speeds of nearly 50 miles per hour. It’s important to cover the mouth with a tissue or elbow, or practice social distancing to help protect others from getting sick.

Good health practices can help lower the risk of infection. This means washing hands often, covering coughs and sneezes and cleaning frequently touched surfaces. It’s also recommended to stay up to date on recommended vaccines and boosters, like the annual flu vaccine.

When to seek medical attention

In many cases, a chest cold may resolve on its own. It’s a good idea, however, to seek medical care for any of the following symptoms:

• A cough with bloody mucus
• A fever that lasts longer than five days or a temperature of 104 degrees Fahrenheit or higher
• Symptoms that last more than three weeks
• Trouble breathing or shortness of breath

Key takeaways

A chest cold, or acute bronchitis, is an illness that may resolve on its own. Some common at-home treatments to help ease symptoms include rest and hydration. With a chest cold, antibiotics are generally not prescribed. Washing one’s hands often and covering coughs and sneezes are some recommended ways to help reduce the risk of getting sick. If symptoms last longer than three weeks or include trouble breathing or a fever of 104 degrees Fahrenheit or higher, it's important to seek care from a health care provider.
