Why winter makes you more vulnerable to colds – a public health nurse explains the science behind the season
Libby Richards, Purdue University
You’ve probably heard “Don’t go outside in the winter with your hair wet or without a coat; you’ll catch a cold.”
That’s not exactly true. As with many things, the reality is more complicated. Here’s the distinction: Being cold isn’t why you get a cold. But it is true that cold weather makes it easier to catch respiratory viruses such as the cold and flu.
Research also shows that lower temperatures are associated with higher COVID-19 rates.
As a professor of nursing with a background in public health, I’m often asked about infectious disease spread, including the relationship between cold and catching a cold. So here’s a look at what actually happens.
Many viruses, including rhinovirus – the usual culprit for the common cold – influenza, and SARS-CoV-2, the virus that causes COVID-19, remain infectious longer and replicate faster in colder temperatures and at lower humidity levels. This, coupled with the fact that people spend more time indoors and in close contact with others during cold weather, are common reasons that germs are more likely to spread.
The flu and respiratory syncytial virus, or RSV, tend to have a defined fall and winter seasonality. However, because of the emergence of new COVID-19 variants and immunity from previous infections and vaccinations decreasing over time, COVID-19 is not the typical cold-weather respiratory virus. As a case in point, COVID-19 infection rates have surged every summer since 2020.
Virus transmission is easier when it’s cold
More specifically, cold weather can change the outer membrane of the influenza virus, making it more solid and rubbery. Scientists believe that the rubbery coating makes person-to-person transmission of the virus easier.
It’s not just cold winter air that causes a problem. Air that is dry in addition to cold has been linked to flu outbreaks. That’s because dry winter air further helps the influenza virus to remain infectious longer. Dry air, which is common in the winter, causes the water found in respiratory droplets to evaporate more quickly. This results in smaller particles, which are capable of lasting longer and traveling farther after you cough or sneeze.
How your immune system responds during cold weather also matters a great deal. Inhaling cold air may adversely affect the immune response in your respiratory tract, which makes it easier for viruses to take hold. That’s why wearing a scarf over your nose and mouth may help prevent a cold because it warms the air that you inhale. https://www.youtube.com/embed/7JQ78oLFV9A?wmode=transparent&start=0 Cold weather can affect nasal immunity.
Also, most people get less sunlight in the winter. That is a problem because the sun is a major source of vitamin D, which is essential for immune system health. Physical activity, another factor, also tends to drop during the winter. People are three times more likely to delay exercise in snowy or icy conditions.
Instead, people spend more time indoors. That usually means more close contact with others, which leads to disease spread. Respiratory viruses generally spread within a 6-foot radius of an infected person.
In addition, cold temperatures and low humidity dry out your eyes and the mucous membranes in your nose and throat. Because viruses that cause colds, flu and COVID-19 are typically inhaled, the virus can attach more easily to these impaired, dried-out passages.
What you can do
The bottom line is that being wet and cold doesn’t make you sick. That being said, there are strategies to help prevent illness all year long:
- Avoid touching your face, something people do between nine and 23 times an hour.
- Stay hydrated. Eight glasses a day of water is a good goal, but that could be more or less depending on lifestyle and the size of the person.
- Eat a well-balanced diet. Dark green, leafy vegetables are rich in immune system-supporting vitamins, while eggs, fortified milk, salmon and tuna have vitamin D.
- Stay physically active, even during the winter.
- Get adequate sleep.
- Clean hard, high-touch surfaces in your home often.
- If your nose or throat gets dry in the winter, consider using a humidifier.
- Get your annual flu and COVID-19 vaccine.
Following these tips can ensure you have a healthy winter season.

Diva Fam Inc. Announces Voluntary Recall of True Sea Moss “Sea Moss Gel Superfood” Products Due to Possible Health Risk
Diva Fam Inc. is recalling all True Sea Moss Sea Moss Gel Superfood flavors nationwide due to missing pH/temperature records and potential botulism risk.
Diva Fam Inc.. announced a voluntary recall of all lots and flavors of its True Sea Moss brand Sea Moss Gel Superfood due to a lack of required regulatory authorization and temperature monitoring records for pH-controlled food products, according to a company statement released January 9, 2026.
The company said the recall applies to products manufactured prior to January 9, 2026. The manufacture date (MFD) is indicated on the can lid in MM/YYYY format.
Why the products are being recalled
Diva Fam said the recall is related to missing required regulatory authorization and temperature monitoring records for certain pH-controlled food products.

Botulism is a rare but serious illness that can affect the nervous system. Symptoms may include general weakness, dizziness, double vision, difficulty speaking or swallowing, and, in severe cases, difficulty breathing or muscle weakness.
Diva Fam said no illnesses or adverse health events have been reported in connection with the products subject to this recall to date.

A Legacy of Service: How family stories shape service
Legacy of Service: Discover how military service creates lasting family legacies across generations. Explore powerful veteran stories from the Veterans History Project, including Pearl Harbor survivors and Code Talkers, and learn how to preserve your family’s service history.
A Legacy of Service: How family stories shape service
(Family Features) Major historical events like war or military service make a lasting impact on family identity, values and traditions, often reverberating across multiple generations. Veterans frequently speak about their military units as if they were family, given the unbreakable bonds that develop between comrades. However, for some veterans, “brothers in arms” is more than a figurative turn of phrase. Throughout the 20th century, entire families felt the firsthand effects of war, with multiple generations serving. Brothers enlisted together. A father’s military legacy inspired his children to join up. Sweethearts met and married while in uniform. These stories not only illustrate the experiences of individual veterans but also provide an intimate glimpse into family legacies of military service. Consider the Veterans History Project, a program overseen by the Library of Congress, which collects and preserves the firsthand remembrances of U.S. military veterans and makes them accessible for future generations to better understand veterans’ service and sacrifice. These personal stories encompass original correspondence, memoirs, diaries, photographs and oral history interviews, all offering deeper insight into the long-term impact of military service. Veterans’ narratives are collected by volunteers, and anyone who served from World War I to today can submit their personal story, regardless of whether or not they saw combat. The collections frequently shed light on the importance of family in military experiences. Whether expressed through heartfelt letters home, enduring family legacies of service or the experience of serving alongside loved ones, these stories reflect profound connections.
Family Identity During the Cold War, Jennifer McNeill rose from Army Dental Assistant to Command Sergeant Major at the Army Eisenhower Medical Center in Fort Gordon, Georgia. Her collection includes a poignant photograph of her mother sharing images of her four military daughters in uniform, underscoring how family identity and military service are closely connected. Values Military service makes a lasting impression on veterans, shaping the experiences and the values that guide them through life. Ray Chavez is one such example. He was the oldest known Pearl Harbor survivor before his passing in 2018. For most of his life, he remained silent about his experiences, but in 1991, his daughter, Kathleen Chavez, who served in the U.S. Navy during Desert Storm, convinced him to return to Pearl Harbor. That trip marked the first time he spoke openly about his service. Kathleen shared their family’s deep military legacy in her oral history for the Veterans History Project. Traditions Across Generations Serving in the military is a deeply personal journey, but for many veterans, it’s an experience that transcends generations. Bill Toledo enlisted in the Marine Corps in October 1942 at the age of 18. Along with his uncle, Frank Toledo, and cousin, Preston Toledo, he served as a Code Talker transmitting military messages through secret codes. In his oral history, Bill vividly recalled both the challenges of combat during the invasion of Iwo Jima in February 1945, and the treasured moments spent with his uncle. These and many other family stories of military service and remembrance are available to the public at loc.gov/vets. Photo courtesy of Shutterstock (men looking at scrapbook)
