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.

From neighborhood restaurants to innovative tech startups, small businesses continue to play a vital role in creating jobs, supporting communities, and inspiring innovation.
According to the U.S. Small Business Administration, small businesses account for millions of jobs nationwide and represent the backbone of local economies. Throughout May, organizations, chambers of commerce, and business leaders host networking events, educational workshops, and promotional campaigns to support entrepreneurs and encourage consumers to shop locally.
One of the highlights of the month is National Small Business Week, which honors outstanding entrepreneurs and business owners making a difference in their communities.
For consumers, Small Business Month is also a reminder that supporting local businesses helps strengthen neighborhoods and keeps communities thriving. Whether it’s dining at a local café, shopping at an independent store, or hiring a local service provider, every purchase can make an impact.

Cruise travel is having more than a moment. It’s having a decade.
(Tiffany Miller) The cruise industry is not waiting for travelers to come around. By most measures, they already have. A projected 21.7 million Americans are expected to cruise in 2026, a record high and a 4.5 percent increase over last year, according to AAA.
“Cruising has come a long way since The Love Boat,” said writer and travel expert Sarah Greaves-Gabbadon, aka JetSetSarah. “Pull up to the port, unpack once and have the world come to you.”
This April, more than 11,500 attendees and 650 exhibitors gathered at Seatrade Cruise Global to map out what comes next.
Dining as the main event
Food has always been part of the cruise experience. The question the industry is now asking is what happens when it becomes the point.
Cruise lines are placing greater emphasis on the dining experience, with destination-inspired menus, port-specific drinks and more immersive, multi-course experiences.
Royal Caribbean introduced the Empire Supper Club this year, pairing multi-course menus with craft cocktails and live music into a single evening.
Expedition cruising finds a new audience
Expedition cruising is one of the fastest-growing types of cruising, and major cruise lines are moving into it.
These itineraries go where other ships do not. Travelers kayak among glaciers, contribute to citizen science programmes and spend time in the field with naturalists and researchers, with programming built around science and conservation rather than port stops.
National Geographic-Lindblad Expeditions has operated in this space for decades, with programs including the Visiting Scientist Program, the Lindblad Expeditions-National Geographic Fund and the Grosvenor Teacher Fellowship.
Wellness expands across the ship
Wellness is no longer a spa deck. It is becoming a reason to book.
A few years ago, a thermal suite was a selling point. Now it is closer to a baseline expectation. Meditation spaces, sleep-focused staterooms and recovery lounges are following the same trajectory. A dedicated wellness pavilion debuted at this year’s show, a signal that the category has grown large enough to need its own floor space.
Cunard’s Wellness at Sea program runs across multiple days. Its three tracks (Relax, Energise and Recover) each combine fitness, spa and mindfulness elements. Shore excursions and destination-specific spa offerings carry the experience beyond the ship.
Ships as cultural hubs
Entertainment on cruise ships used to mean a stage show. Cruise lines are now producing content that doesn’t exist anywhere else.
Holland America Line partnered with The Verdon Fosse Legacy to debut “Fosse and Verdon, The Duet That Changed Broadway,” a live musical and multimedia tribute to the work of Bob Fosse and Gwen Verdon. The production marks the first international staging of their work at sea.
Onboard retail is moving in the same direction. More cruise lines are curating locally sourced goods and destination-specific products at port, the kind passengers could only find by actually being there.
The bigger picture
The passenger numbers tell one part of the story. What cruise lines are building inside that growth tells another.
“Today’s ships offer amenities that are at least as good as, and often more comprehensive than, those in resorts and hotels,” Greaves-Gabbadon said. “A cruise can be equally enjoyable for solos, families, honeymooners, groups and adventurers, and that versatility is a large part of their appeal.”
What the show floor made clear is that the industry is not waiting to be discovered. It is building toward the traveler it wants next.
