Understanding Colds in Older Adults: Risks and Recovery

We all get the sniffles. It’s a common part of life that you just have to get through. But as you get older, you may notice that it takes longer to recover. Here’s what to know about colds in older age, and why they may be something you need to watch more carefully.

What You Should Worry About

Colds are usually mild infections of the upper respiratory tract—the nose and throat—most often caused by viruses.

How often you get colds generally decreases with age. Adults typically get about two to three colds per year, while children may get six or more. Older adults often get even fewer infections, partly because they’ve already been exposed to many viruses over their lifetime and have some immune memory.

Despite this, older adults are often told to be more careful and avoid getting colds as much as possible. So why does it matter more with age? The issue is not that older adults get more colds. It’s that when they do get sick, the illness is more likely to be serious—or to turn into something more serious than a cold.

“Although older healthy adults are healthier than their inactive peers, the aging process does make this group somewhat more vulnerable to severe infections compared to younger, healthy adults,” Dr. Paul Savage, toxin expert and the founder and CEO of MDLifespan told Nifty50+.

The CDC notes that influenza, RSV, and COVID-19 can all start with cold-like symptoms but are far more likely to cause severe illness in older adults and those with underlying conditions.

You have a higher risk of complications if you:

• Are 65 or older
• Have certain health conditions such as asthma or diabetes
• Have heart disease or have had a stroke
• Live in a nursing home or other long-term care facility

What Happens With Age?

It’s important to remember that getting older does not automatically mean being unhealthy—many people reach later life with few serious problems. But aging does come with several interconnected changes that can make the body more vulnerable to illness.

As we age, the immune system changes in ways that make infections harder to fight. Scientists call this immunosenescence, an age-related decline in immune function that affects how well the body responds to new infections.

“This decrease in power in the immune system can come from nutritional deficiencies, hormone deficiencies, toxin exposure, chronic infections, chronic inflammation, aging lung cells themselves, and the onset of other diseases such as diabetes,” Savage explained.

At the same time, older adults often experience “inflammaging,” a chronic low-grade inflammatory state that can worsen tissue damage during infections.

In simple terms, the body becomes slower at clearing viruses but quicker to trigger inflammation, and that combination can make infections harder on the body. 

The lungs also change with age. The airways clear mucus less effectively, the cough reflex weakens, and lung elasticity declines. This makes it easier for infections to move deeper into the lungs, which is one reason respiratory infections are a major cause of serious illness in older adults. Pneumonia and influenza together are among the leading causes of death in people 65 and older, and about 85–90% of these deaths occur in this age group.

Age-related changes may also help explain why respiratory infections can hit older adults harder.

For instance, a recent study found that in older adults, the lungs themselves may drive inflammation during infections. Aging lung cells send distress signals that trigger an excessive immune response, which can damage the lungs and make otherwise mild infections become severe.

“We saw during COVID that our most vulnerable patients no longer had the infection but still had persistent and devastating lung inflammation,” Dr. Tien Peng, a professor of medicine, and senior author of the study said in a news release.

“Although older healthy adults are healthier than their inactive peers, the aging process does make this group somewhat more vulnerable to severe infections compared to younger, healthy adults.”

Same Virus, Higher Stakes

The same viruses that cause colds in younger people also infect older adults—but the stakes are higher.

A cold usually starts in the upper airways, causing a runny nose, sore throat, and cough. But in older adults, the infection is more likely to move down into the lower respiratory tract. The virus can damage the airway lining, and mucus is cleared less effectively, allowing secretions to build up in the lungs. This creates an environment where bacteria can grow, leading to secondary bacterial pneumonia—a common and serious complication in older adults.

When pneumonia develops, the tiny air sacs in the lungs fill with fluid and pus, making it harder for oxygen to enter the bloodstream. In severe cases, this can lead to respiratory failure, sepsis, or organ failure.

Respiratory infections can also worsen existing conditions such as heart disease, diabetes, or chronic lung disease. As Dr. Savage noted, “Older, healthy adults need not worry greatly about getting colds. But older adults with health issues, especially related to their immune system, diabetes, heart disease or lung compromise, need to take care.”

This is why an illness that might be a nuisance in midlife can become a serious setback later in life.

How to Lower Your Risk

Older adults cannot avoid every cold virus, but they can lower the risk of serious illness.

Dr. Savage offers a list to prevent getting sick:

• Maintain your health. Eat well, such as a Mediterranean diet, and exercise daily, rotating between weight resistance, cardio, balance, and stretching.
• Take nutrients. Most of us do not absorb nutrients as readily as when we were younger.  Take a top brand vitamin/mineral supplements containing vitamin A, C, D3, and E along with minerals such as zinc and selenium.
• Get plenty of good sleep. Sleep in a completely dark, completely quiet (or white noise), slightly cool environment for 7-9 hours per night if possible.
• Wear a mask when outside in public. An N95 mask will markedly reduce your exposure not only to airborne viruses, but airborne toxins as well.
• Wash your hands and face regularly with soap and water.
• See your doctor regularly, and take your medications as instructed.

If you get sick, rest early, drink plenty of fluids, and eat simple, nutritious foods. If you are at higher risk, contact your doctor sooner rather than later — early care can help prevent complications. Dr. Savage also recommends seeking medical advice promptly and discussing vaccination options. 

“Discuss with your doctor the pros and cons of the various vaccines for you,” Savage said. While vaccines for flu, COVID-19, RSV, and pneumococcal disease do not prevent every infection, public health agencies note that they can significantly reduce the risk of hospitalization and death.

Take Them Seriously

Most colds are still mild, even in older adults. But the risk of complications is higher, and cold-like symptoms may sometimes be something more serious.

So it’s not about being afraid of every sniffle — it’s about recognizing that infections are harder on the body as we age, and getting help sooner rather than later when something doesn’t feel right.
